Which graph shows the correct solution for y=-3 x-y=8
Answer:
"Third graph" in the attached picture.
Step-by-step explanation:
The correct graph would be the "intersection" of the lines:
y = -3, and
x - y = 8
We know, y = -3 is a horizontal line at y = -3 and the next is a line. By looking at the first equation, we can eliminate 2 graphs and thus find the correct graph.
y = -3 is a horizontal line at y = -3, the first graph has the line y = 3, so we can eliminate this even without looking at the graph of 2nd equation.
The second graph has a vertical line, no horizontal, so we can eliminate this choice as well.
The third graph has y = -3 (horizontal line at y = -3) and thus this is the correct choice. Also, x - y = 8 means y = x -8, which is the other graph shown.
correct answer is the "third graph".
Answer: last option.
Step-by-step explanation:
The equation of the line in slope-intercept form is:
[tex]y=mx+b[/tex]
Where m is the slope and b the intersection with the y-axis.
The line [tex]y=-3[/tex] is a line with slope 0 that cut the y-axis at (0,-3)
Solve for y from the second equation:
[tex]x-y=8\\x-8=y[/tex]
The line [tex]y=x-8[/tex] is a line with slope 1 that cut the y-axis at (0,-8)
You can identify these lines in the last graph, where the point of intersection between them is the solution of the system of equations.
a carpenter agrees to work under the condition that she is to be paid $55 every day she works and she must pay $66 every day she does not work. at the end of 30 days, she finds she has earned 77$. how many days did she work?
Answer:
17 days
Step-by-step explanation:
For each day she works, she earns +55 and each day she DOES NOT work she earns -66. Total 30 days.
Let number of days she works be x
thus, number of days she DOES NOT work is 30 - x
We can setup an equation as:
55(x) + -66(30-x) = 77
This means, she works x days for 55 each and 30 - x days getting -66 each, totalling 77.
We can solve for x to find number of days she worked. Work shown below:
[tex]55(x) + -66(30-x) = 77\\55x-66(30)+66x=77\\121x -1980 = 77\\121x = 77+1980\\121x = 2057\\x=\frac{2057}{121}\\x=17[/tex]
Thus, she worked 17 days

The Earth completely rotates on its axis once every 24 hours.
A) How long does it take for it to rotate 310 degrees?
B) How long does it take to rotate 5 radians?
C) The diameter of the Earth is approximately 7920 miles. How far will a point on the equator rotate in 2 hours?
Show all work. Give answers to the nearest hundredth. Include the units in your response.
Answer:
A)
62/3 = 20.67 hours
B)
60.00 hours
C)
2074.29 miles
Step-by-step explanation:
If we assume the earth is a perfect circle, then in a complete rotation the earth covers 360 degrees or 2π radians.
A)
In 24 hours the earth rotates through an angle of 360 degrees. We are required to determine the duration it takes to rotate through 310 degrees. Let x be the duration it takes the earth to rotate through 310 degrees, then the following proportions hold;
(24/360) = (x/310)
solving for x;
x = (24/360) * 310 = 62/3 = 20.67 hours
B)
In 24 hours the earth rotates through an angle of 2π radians. We are required to determine the duration it takes to rotate through 5π radians. Let x be the duration it takes the earth to rotate through 5π radians, then the following proportions hold;
(24/2π radians) = (x/5π radians)
Solving for x;
x = (24/2π radians)*5π radians = 60 hours
C)
If the diameter of the earth is 7920 miles, then in 24 hours a point on the equator will rotate through a distance equal to the circumference of the Earth. Using the formula for the circumference of a circle we have;
circumference = 2*π*R = π*D
= 7920π miles
Therefore, the speed of the earth is approximately;
(7920π miles)/(24 hours) = 330π miles/hr
The distance covered by a point in 2 hours will thus be;
330π * 2 = 660π miles = 2074.29 miles

Marlon built a ramp to put in front of the curb near his driveway so he could get to the sidewalk more easily from the street on his bike.
If the ramp includes the flat piece as well as the angled piece and is made entirely out of concrete, what is the total amount of concrete in the ramp?
768in^3
936in^3
984in^3
1,080in^3
Answer: Last option.
Step-by-step explanation:
The total amount of concrete in the ramp ([tex]V_t[/tex]) will be the sum of the volume of the rectangular prism ([tex]V_{rp}[/tex]) and the volume of the triangular prism ([tex]V_{tp}[/tex])
[tex]V_t=V_{rp}+V_{tp}[/tex]
The formulas are:
[tex]V_{rp}=lwh[/tex]
Where "l" is the lenght, "w" is the width and "h" is the height.
[tex]V_{tp}=\frac{bhl}{2}[/tex]
Where "l" is the lenght, "b" is the base and "h" is the height.
Substituting, we get:
[tex]V_t=V_{rp}+V_{tp}\\\\V_t=lwh+\frac{bhl}{2}\\\\V_t=(18in)(6in)(6in)+\frac{(8in)(6in)(18in)}{2}\\\\V_t=1,080in^3[/tex]

Answer:
first choice: (x, y) ------> (x + 3, y - 2)
Step-by-step explanation:
The x-coordinate started as 4. Then it became 7. To change from 4 to 7, you add 3. The rule for x is to add 3.
The y-coordinate started as -8. Then it became -10. To go from -8 to -10, you subtract 2. The rule for y is to subtract 2.
Look at the choices, and pick the one that adds 3 to x and subtract 2 from y.
The answer is the first choice: (x, y) ------> (x + 3, y - 2)

Therefore the correct answer is option D. 2700 units²
If sin x = -3/5 and x is in quadrant 3, then tan2x
Answer:
i think it should be tan2x = 24/7, i hope i am not wrong
Step-by-step explanation:
If sin x = -3/5 and x is in quadrant 3, then tan 2x = 24/7.
How to estimate the value of tan 2x?
Given:
[tex]$Sin x = \frac{-3}{5}[/tex]
To estimate cos x by identity
[tex]$Cos^{2} x=1-Sin^{2} x[/tex]
[tex]$Cos^{2} x =1-\frac{9}{25}[/tex]
[tex]$=\frac{16}{25}[/tex]
cos x = ±(4/5)
Since x exists in Quadrant III, then cos x exists negative.
tan x = Sin x/Cos x
= (−35)/(−54) = 3/4
By using the trigonometric identity, we get
tan 2x = 2 tan x / [tex]$1-tan^{2} x[/tex]
tan 2x = (6/4) / (1−9/16)
= (6/4)(16/7)
= 24/7
Therefore, tan 2x = 24/7.

The chord is bisected as shown by the perpendicular lines and right angle, so both segments are 6.
Draw a radius from the center to the end of the chord to create a right triangle. 8 and 6 are the legs, use pythagorean theorem to find the length of the segment you drew because its the hypotenuse.
8^2+6^2=x^2
64+36
100
square root of 100 is 10
So, 10 is the length of the segment. Both the x segment and the 10 segment are radii because they are draw from the center to a point on the circle.
They are equal.
x=10
ANSWER
10
EXPLANATION
The value of x is the radius of the circle.
The radius of the circle is also the hypotenuse of the right triangle formed by the chord, the radius and the segment bisecting the chord through the center.
We apply the Pythagoras Theorem to obtain:

Together, a chair, a table, and a lamp cost $562. The chair costs 4 times as much as the lamp, and the table costs $23 less than the chair. Calculate the cost of the chair, the table, and the lamp.
Answer:
The cost of chair is [tex]\$260[/tex]
The cost of a lamp is [tex]\$65[/tex]
The cost of a table is [tex]\$237[/tex]
Step-by-step explanation:
Let
x----> the cost of chair

Explain the steps used to convert a temperature from Celsius to Fahrenheit.
For this case we have that by definition, to move from Celsius to Fahrenheit we must apply the following formula:
[tex]F = \frac {9} {5} C + 32[/tex]
Example, we want to convert 45 degrees Celsius to Fahrenheit:
[tex]F = \frac {9} {5} (45) +32\\F = 9 * 9 + 32\\F = 81 + 32\\F = 113[/tex]
Thus, 45 degrees Celsius equals 113 degrees Fahrenheit.
ANswer:[tex]F = \frac {9} {5} C + 32[/tex]
For anyone who still needs this:
1. Multiply your Celsius measurement by 9/5 (or 1.8)

Assignment 01.11 Estimating
Step 1- Read the passage Who was Leonardo da Vinci?
Who was Leonardo da Vinci?
Leonardo da Vinci trained as a painter during the Renaissance and became a true master of the craft. His amazing powers of observation and skill as an illustrator enabled him to notice and recreate the effects he saw in nature, and added a special liveliness to all of his portraits. Curious as well as observant, he constantly tried to explain what he saw, and described many experiments to test his ideas. Because he wrote down and sketched so many of his observations in his notebooks, we know that he was among the very first to take a scientific approach towards understanding how our world works and how we see it. He had a keen eye and quick mind that led him to make important scientific discoveries, yet he never published his ideas. He was a gentle vegetarian who loved animals and despised war, yet he worked as a military engineer to invent advanced and deadly weapons. He was one of the greatest painters of the Italian Renaissance, yet he left only a handful of completed paintings.

Q1. 168 words from sixth sentence.
Q2. 171 words from line 3.
Q3. 177 words from the first three sentences.
Q4. Method 3.
Step-by-step explanation:
Question 1.
The paragraph has seven sentences.
I chose the sixth sentence ("gentle vegetarian"). It contains 24 words.
7 sentences × (24 words/1 sentence) = 168 words
Question 2.
The passage contains 19 lines.
I chose line 3 ("amazing powers"). It contains nine words.
19 lines × (9 words/1 line) = 171 words.
Question 3.
I chose the first three lines. They contain 28 words.
Words per line = 28 words/3 lines = 9.33 words per line
Total words = 19 lines × (9.33 words/1 line) = 177 words
Question 4
The passage contains 176 words. Method 3 comes closest to the actual number of words.

In a triangle, the measure of the first angle is three times the measure of the second angle. The measure of the third angle is 70 degrees more than the measure of the second angle. Use the fact that the sum of the measures of the three angles of a triangle is 180 degrees to find the measure of each angle.
The measure of the first angle is _____
Answer:
66
Step-by-step explanation:
x is the second angle
3x is the first angle
x+70 is the third angle
x+3x+x+70=180
5x = 110
x= 22
first angle: 3x = 3*22 = 66
Answer:
Second angle: 22°
And the other angles are:
First angle: 66°
Third angle: 92°
Step-by-step explanation:
Let be:
[tex]x[/tex] the measure of the second angle.
[tex]3x[/tex] the measure of the first angle.
[tex](x+70)[/tex]: the measure of the third angle.
Then, knowing that the sum of the interior angles of a triangle is 180 degrees, you can write this expression and solve for "x",to calculate the measure of the second angle:
[tex]x+3x+(x+70)=180\\5x+70=180\\5x=180-70\\\\x=\frac{110}{5}\\\\x=22\°[/tex]
You can also know that:
First angle:
[tex]3x=2(22\°)=66\°[/tex]
Third angle:
[tex]x+70\°=22\°+70\°=92\°[/tex]
A machine is set up to cut metal strips of varying lengths and widths based on the time (t) in minutes. The change in length is given by the function `l(t) = t^2 - sqrt(t)`, and the change in width is given by `w(t) = t^2 - 2t^(1/2)`. Which function gives the change in area of the metal strips? A. `a(t) = t^4 + 2t` B. `a(t) = t^4 + 2t + 3t^(5/2)` C. `a(t) = t^4 - 3t^(5/2) + 2t` D. `a(t) = t^4 + 2t - 2t^(1/2) + sqrt(t)`
Answer:
The change of area A(t) = t^4 - 3t^(5/2) + 2t ⇒ answer C
Step-by-step explanation:
* Lets study the problem
- The metal strip is in a shape of rectangle
- The change in length l(t) = t² - √t
- The change is the width w(t) = t² - 2t^1/2
* We must find function gives the change of area
∵ The area of the rectangle = length × width
∴ The change of rate of area A(t) = l(t) × w(t)
- We can write the √t in exponential form t^1/2
∴ l(t) = t² - t^1/2
∵ w(t) = t² - 2t^1/2
∵ A = l × w
∴ A(t) = l(t) × w(t)
∴ [tex]A(t)=(t^{2}-t^{\frac{1}{2}})(t^{2}-2t^{\frac{1}{2}})[/tex]⇒use the foil method
∴ [tex]A(t)=(t^{2})(t^{2})+(t^{2})(-2t^{\frac{1}{2}})+(-t^{\frac{1}{2}})(t^{2})+(-t^{\frac{1}{2}})(-2t^{\frac{1}{2}})[/tex]
- If we multiply two same numbers have exponents, then we add
the power of them
∴ [tex]A(t)=(t^{2+2})-2t^{2+\frac{1}{2}}-t^{\frac{1}{2}+2}+2t^{\frac{1}{2}+\frac{1}{2}}[/tex]
∴ [tex]A(t)=t^{4}-2t^{\frac{5}{2}}-t^{\frac{5}{2}}+2t[/tex]
* Now lets add the like terms
∴ [tex]A(t)=t^{4}-3t^{\frac{5}{2}}+2t[/tex]
* The change of area A(t) = t^4 - 3t^(5/2) + 2t

A density curve for all the possible ages between 0 years 50 years is in the shape of a triangle,what is the height of the triangle
Answer: The answer is 0.04
Step-by-step explanation:
To determine the height of a triangle-shaped density curve spanning from 0 to 50 years, we use the fact that the area under the density curve must equal 1. The equation (50 * height) / 2 = 1 allows us to solve for the height, which is 0.04 on the probability density scale.
Explanation:To determine the height of the triangle representing a density curve for possible ages, we need some information about the properties of that triangle and density curves in general. A density curve shows how the proportion of a particular measurement (in this case, ages) is spread out over a range. The area under a density curve must equal 1 (or 100%) since it represents the total probability distribution.
In this scenario, we have a triangle as a density curve stretching from 0 to 50 years, which suggests that 0 and 50 are the bounds of our variable (age). The base of the triangle spans these 50 years. If we assume a right-angled triangle for simplicity's sake (which isn't specified in the question but is a common assumption), then the area of the triangle, which represents the probability, would be (base * height) / 2.
To ensure that the total area under the curve equals 1, we set up the following equation: (50 * height) / 2 = 1. Solving this equation for height gives us height = 2 / 50, which simplifies to height = 0.04. Therefore, the height of the density triangle is 0.04 on whatever scale is being used for probability density (e.g., per year).
