Answer:
The x-intercept is the ordered pair (9,0)
Step-by-step explanation:
we know that
The x-intercept is the value of x when the value of y is equal to zero
so
The x-intercept is a ordered pair with a y-coordinate equal to zero
therefore
In this problem
The x-intercept is the ordered pair (9,0)
The x-intercept from the list of ordered pairs (8,10), (3,-4), (0,8), (4,-3), (9,0) is 9, as it is the x-value of the pair where the y-coordinate is zero.
Explanation:To find the x-intercept from a list of ordered pairs, you need to look for the pair where the y-coordinate is zero. The x-intercept is the x-value in this pair.
From the list of ordered pairs given in the question, which are (8,10), (3,-4), (0,8), (4,-3), (9,0), we identify that the x-intercept is in the pair where y is equal to 0.
Thus, the x-intercept from the list is 9, as it appears in the ordered pair (9,0).

a) Write an equation for the amount of money (m) Scott has after a number of hours babysitting (h).
b) After how many hours of babysitting will Scott have $51.00?
(a) m=6h+15 can be used to find the total amount of money for h hours of babysitting.
(b) After 6 hours of babysitting, Scott will have $51.00
Step-by-step explanation:
Given,
Amount Scott has = $15.00
Per hour amount of babysitting = $6.00
a) Write an equation for the amount of money (m) Scott has after a number of hours babysitting (h).
Total amount of money = m
Number of hours babysitting = h
Total amount of money = Per hour earning from babysitting*Number of hours + Amount Scott has
[tex]m=6h+15[/tex]
m=6h+15 can be used to find the total amount of money for h hours of babysitting.
b) After how many hours of babysitting will Scott have $51.00?
Putting m = 51
[tex]51=6h+15\\51-15=6h\\36=6h\\6h=36[/tex]
Dividing both sides by 6
[tex]\frac{6h}{6}=\frac{36}{6}\\h=6[/tex]

If x/a = 4, a/y = 6, a2 = 9 and ab2 = −8 then x + 2y = ?
Select one:
A. −10
B. −15
C. −5
D. −13
Answer:
-13
Step-by-step explanation:
We are given:
[tex]\frac{x}{a}=4[/tex]
[tex]\frac{a}{y}=6[/tex]
[tex]a^2=9[/tex]
[tex]ab^2=-8[/tex]
Since [tex]ab^2=-8[/tex] then [tex]a[/tex] has to be negative.
Solving [tex]a^2=9[/tex] therefore gives [tex]a=-3[/tex].
(Note: [tex](-3)^2=(-3)(-3)=9[/tex].)
[tex]\frac{x}{a}=4[/tex] and [tex]a=-3[/tex] gives us:
[tex]\frac{x}{-3}=4[/tex].
Multiplying both sides by -3 gives: [tex]x=-12[/tex].
[tex]\frac{a}{y}=6[/tex] and [tex]a=-3[/tex] gives us:
[tex]\frac{-3}{y}=6[/tex].
Multiplying both sides by [tex]y[/tex] gives: [tex]-3=6y[/tex].
Divide both sides by 6 gives: [tex]\frac{-3}{6}=y[/tex].
Simplifying this gives us [tex]\frac{-1}{2}=y[/tex].
Now we are asked to find the numerical value for [tex]x+2y[/tex].

A(one-third, 0)
B(3, infinity)
C(negative infinity, 3)
D(negative infinity, positive infinity)
Answer:
Option B is the required answer.Step-by-step explanation:
As per the given question, [tex]u(x) = -2x^{2}[/tex] and [tex]v(x) = \frac{1}{x}[/tex].
Hence, (u circle v) (x) = u{v(x)} = [tex]\frac{-2}{x^{2} }[/tex]
The range of the function, (u circle v) (x) means the set of the values of x so that we will be able to get a proper finite, countable and exact value of the function.
For the above function, (u circle v) (x) we can not get a proper value of the function for x = 0.
Hence, the options A, C, D can not be the range of the function, since it contains 0.
The range of the given function will be the option B, since it does not contain the value 0.

Answer:
e) Shamika= 224 balloon, Crystal= 112 balloon, Aliya= 114 Balloon.
f) We know,Crystal sold "b" balloon
Aliya sold (b+2) balloon
Shamika sold 2b balloon.
As per data given in question part c that each balloon cost $2 and Total cost of balloon is $900.
Now, solving to find how much each student sold balloon at school´s winter dance.
As we know total cost is $900 and each balloon cost is $2.
∴ Total cost= [tex]Total\ quantity \times cost\ of\ each\ unit[/tex]
Total quantity= [tex]{b+(2+b)+2b}[/tex]
∴ [tex]\$ 900= {b+(2+b)+2b}\times \$ 2[/tex]
Once we solve, we will get the value of b as 112 balloon, which is the number of balloon sold by Crystal.
Substituting the value of b in the equation of Aliya and Shamika, we will get the number of balloon sold by them.
Which is 114 and 224 respectively.
Step-by-step explanation:
Given: Crystal sold "b" balloon
Aliya sold (b+2) balloon
Shamika sold 2b balloon.
As per data given in question part c that each balloon cost $2 and Total cost of balloon is $900.
Now, solving to find how much each student sold balloon at school´s winter dance.
As we know total cost is $900 and each balloon cost is $2.
∴ Total cost= [tex]Total\ quantity \times cost\ of\ each\ unit[/tex]
Total quantity= [tex]{b+(2+b)+2b}[/tex]
∴ [tex]\$ 900= {b+(2+b)+2b}\times \$ 2[/tex]
Opening the parenthesis.
⇒[tex]\$ 900= (b+2+b+2b)\times \$ 2[/tex]
⇒[tex]\$ 900= 2+4b \times 2[/tex]
Dividing both side by 2
⇒ [tex]\$ 450= 2+4b[/tex]
Subtracting both side by 2
⇒ [tex]\$ 448= 4b[/tex]
Cross multiplying
∴[tex]b= \frac{448}{4} = 112[/tex]
∴ b= 112.
Hence, we can say Crystal have sold 112 balloons.
Next subtituting the value of "b" in the equation for Aliya and Shamika to get number of balloon they have sold.
We know, Aliya sold b+2 balloons
∴ Aliya sold= [tex]112+2= 114\ balloon[/tex]
Aliya sold 114 balloon.
We know, Shamika sold 2b balloons
∴[tex]2\times 112= 224 balloon.[/tex]
Shamika sold 224 balloon.

Orlando worked $6/h one week and $7/h the next week. He worked 5 more hours the second week than the first and earned $347 for the 2 weeks of work. How many hours did he work each week?
Answer:
24 hours in first week and 29 hours in second week.
Step-by-step explanation:
Given: Orlando work at $6/h in first week and at $7/h in second week.
Total earning is $347 in both weeks.
Let the number of hours Orlando work in first week be`x` hours
∴ working hours in second week is (x+5) hours
Now, solving to find the number of working hours.
⇒ Total earning= earning in first week+earning in second week.
⇒ [tex]\$ 347= x\times 6+(x+5)\times 7[/tex]
Opening the parenthesis and solving it.
⇒ [tex]\$ 347= 6x+7x+35[/tex]
Subtracting both side by 35
⇒ [tex]312= 13x[/tex]
∴ x= [tex]\frac{312}{13} = 24\ h[/tex]
∴ Working hours in first week is 24 hours
Working hours in second week is [tex]24+5= 29\ h[/tex]
Zahra runs an 800 meter race at a constant speed. Which graph shows her distance from the finish line during the race?
Answer:
The graph is attached below.
Step-by-step explanation:
Given:
Zahra runs a 800-meter race at a constant speed.
Race starts from the finish line.
Finish line is at a distance of 800 m from the starting point.
Time is plotted on the x axis and Distance is plotted on the y axis.
So, the graph must start from the [tex]800^{th}[/tex] mark on the y axis when time is 0.
Now, the speed is constant which means that the slope of the line of distance versus time is a straight line because,
Speed [tex]=\frac{Distance}{TIme}[/tex].
Now, the graph should have the following properties:
1. Starting point of the graph should be (0, 800).
2. Final point of the graph should be (t, 0).
3. Slope should be constant everywhere. So, the graph must be a straight line.
Thus, the graph is a line joining the points (0, 800) and (t, 0) as shown below.

what is the value of sin0 given that (-6,-8) is a point on the terminal side of 0
Answer:
[tex]sin \theta =\frac{-8}{10} =-\frac{4}{5}[/tex]
Step-by-step explanation:
For this case we have a point given (-6,-8) and we know that this point is terminal side of 0
We can assume that the length of th opposite side is given by:
b=-8 and the length for the adjacent side would be a=-6
And we can find the hypothenuse on this way:
[tex] c= \sqrt{a^2 +b^2}=\sqrt{(-6)^2 +(-8)^2}=10[/tex]
From the definition of sin we know this:
[tex]sin O =\frac{opposite}{hypothenuse}[/tex]
And if we replace we got this:
[tex]sin \theta =\frac{-8}{10} =-\frac{4}{5}[/tex]
We can aslo find the cos with the following identity:
[tex]cos^2 \theta + sin^2 \theta = 1[/tex]
And then:
[tex]cos \theta = \pm \sqrt{1-sin^2 \theta}=\pm \sqrt{1- (-4/5)^2}=\pm \frac{3}{5}[/tex]
But since both corrdinates are negative we are on the 3 quadrant and then [tex]cos \theta= -\frac{3}{5}[/tex]
A baseball team played 154 regular season games. The ratio of the number of games they won to the number of games they lost was 5/2. How many games did they win?
Answer:
Number of games won = 110
Step-by-step explanation:
Given:
Total games played = 154
The ratio of number of games won to number of games lost = [tex]\frac{5}{2}[/tex]
Solution:
Let the number of games won be = [tex]5x[/tex]
Thus, number of games lost = [tex]2x[/tex]
The total games played can be given as = [tex]5x+2x=7x[/tex]
Thus, we have:
[tex]7x=154[/tex]
Dividing both sides by 7.
[tex]\frac{7x}{7}=\frac{154}{7}[/tex]
∴ [tex]x=22[/tex]
So, number of games won = [tex]5\times 22 = 110[/tex]

Eric and his wife are each starting a saving plan. Eric will initially set aside $50 and then add $30.65 every week to the savings. The amount A (in dollars) saved this way is given by the function A=50+30.65N, where N is the number of weeks he has been saving.
His wife will not set an initial amount aside but will add $55.85 to the savings every week. The amount B (in dollars) saved using this plan is given by the function B= 55.85N.
Let T be the total amount in dollars saved using both plans combined. Write and equation relation T to N. Simplify your answer as much as possible
Answer:
T=50+86.49N

you just have to combine A and B.
Total (T)=A(50+30.65N)+B(55.85N) thank just open the prentices and add 30.65N and 55.85N=86.49N. so total is initial savings+ weekly savings by both.
3. If f(x)= 3x+ 2 , what is the equation for f^-1(x)
Answer:
option 3 ⇒ f⁻¹(x) = [tex]\frac{x^{2} -2 }{3} [/tex]
Step-by-step explanation:
Given F(x) = [tex]\sqrt{3x+2}[/tex]
let y = f(x)
y = [tex]\sqrt{3x+2}[/tex] ⇒ squaring the both sides
y² = 3x + 2 ⇒ subtract 2 from both sides
y² - 2 = 3x ⇒ divide both sides by 3
[tex]\frac{y^{2} -2 }{3} = x[/tex]
replace the location of x and y
∴ y = [tex]\frac{x^{2} -2 }{3} [/tex]
So, y will be f⁻¹(x)
∴ f⁻¹(x) = [tex]\frac{x^{2} -2 }{3} [/tex]

To the nearest degree, what us the angle measure if the angle formed with the positive x-axis and the equation given below
Y=5/4 (x)
The measure of the angle formed with the positive x-axis and the equation of the given line is 51° to the nearest degree
Step-by-step explanation:
The formula to find the angle between the positive part of x-axis and a line y = m x + b is tan(Ф) = m, where
Ф is the angle between the line and the positive part of x-axism is the slope of the line∵ The equation of the line is [tex]y=\frac{5}{4}x[/tex]
∵ The form of the equation of a line is y = m x + b
∴ m = [tex]\frac{5}{4}[/tex] and b = 0
∵ Ф is the angle between the line and the positive part of x-axis
∵ tan(Ф) = m
∴ tan(Ф) = [tex]\frac{5}{4}[/tex]
- To find Ф use the inverse function of tan ( [tex]tan^{-1}[/tex]
∵ Ф = [tex]tan^{-1}(\frac{5}{4})[/tex]
∴ Ф = 51.34°
- Round it to the nearest degree
∴ Ф = 51°
The measure of the angle formed with the positive x-axis and the equation of the given line is 51° to the nearest degree

Step-by-step explanation:
Since ΔEFG ~ ΔABC, they are proportionately related. Each of the corresponding sides differ by the scale factor, which shows how much bigger or smaller the new triangle is from the original triangle.
Purple = original triangle, triangle 1
Pink = new triangle, triangle 2
Find the scale factor, "k". It will be a fraction because the triangle gets smaller.
k = FG/BC = 2/3
The scale factor can be used to find a side, the height or the area of the new triangle.
Use the scale factor squared to find the area.
A₂ = (A₁)(k²)
= (18 ft²)(2/3)²
= 7.999...ft²
= 8 ft²
if the number of square centimetire on the surface of a sphear is equal to the number of cubic centimetres in its volume what is the diameter of the sphere
Answer:
The diameter of the sphere is 6 centimeters
Step-by-step explanation:
we know that
The surface area of a sphere is
[tex]SA=4\pi r^{2}[/tex]
The volume of the sphere is
[tex]V=\frac{4}{3}\pi r^{3}[/tex]
Equate both formulas
[tex]\frac{4}{3}\pi r^{3}=4\pi r^{2}[/tex]
Simplify
[tex]\frac{1}{3}r^{3}=r^{2}[/tex]
[tex]\frac{r^3}{r^2}=3[/tex]
[tex]r=3\ cm[/tex]
Remember that the diameter is two times the radius
so
[tex]D=2r=2(3)=6\ cm[/tex]
therefore
The diameter of the sphere is 6 centimeters
Final answer:
The diameter of a sphere where the surface area equals the volume is 1.5 cm.
Explanation:
To find the diameter of a sphere where the surface area in square centimeters is equal to the volume in cubic centimeters, we use the formulae for the surface area and volume of a sphere:
Surface Area (SA) = 4πr²Volume (V) = 4/3πr³Since the surface area is equal to the volume (SA = V), we can set the equations equal to each other and solve for the radius (r):
4πr² = 4/3πr³r³/r² = 3/4r = 3/4Now that we have the radius, we can find the diameter, which is twice the radius:
Diameter (d) = 2r = 2 × (3/4) = 3/2 cm or 1.5 cm

Now, the volume of the small unit cubes of side lengths of [tex]\frac{1}{2}[/tex] feet will be [tex](\frac{1}{2})^{3} = \frac{1}{8}[/tex] cubic feet.
So, the number of small cubes required to fill the large cube will be [tex](\frac{45}{4} \div \frac{1}{8}) = 90[/tex]. (Answer)

Answer:
x = 31°
Step-by-step explanation:
Since, CB ║ FG and AB is a transverse, so ∠ BAG = ∠ ABC = 28° {Alternate angles}
Now, ∠ CAG = 90° = ∠ CAD + ∠ BAG
⇒ ∠ CAD = 90° - 28° = 62°
From, Δ ADE, ∠ ADE + ∠ DEA + ∠ EAD = 180°
⇒ ∠ ADE = 180° - 62° - 3x = 118° - 3x.
Now, ADB being a straight line, so ∠ ADE + ∠ EDC + ∠ CDB = 180°
⇒ 118 - 3x + x + 4x = 180
⇒ 2x = 62
⇒ x = 31° (Answer)
