Answers
Answer:
3/-3 basically -1
Step-by-step explanation:
do the y2-y1 / x2-1 formula and put the coordinates in and that is:
3-0 / -13- -10
or
3/-3
or -1
BTW: if the numerator and denominator are both negative,
Answer:
Step-by-step explanation:
(-10,0) and (-13,3)
Slope m = (y2 - y1)/(x2 - x1)
y2 = 3, y1 = 0, x2 = -13, x1 = -10
: m = (3 - 0)/(-13 + 10)
m = 3/-3
m = -1
Slope m = -1
In one hour miles ran 16 1/4 miles. How far could miles run in 2 1/2 hours?
Answers
Answer:
40.625 miles covered in 2.5 hours
Step-by-step explanation:
Given that [tex]16 \frac{1}{4} [/tex]
miles was ran in one hour, then to find miles run in 2.5 hours, we just have to multiply:
[tex]16 \frac{1}{4} [/tex]
by [tex]2 \frac{1}{2} [/tex]
This means that miles run in 2½ hours
[tex] = 16 \frac{1}{4} \times 2 \frac{1}{2} [/tex]
[tex] = \frac{65}{4} \times \frac{5}{2} [/tex]
[tex] = \frac{325}{8} [/tex]
[tex] = 40 \frac{5}{8} = 40.625[/tex]
Therefore 40.625 miles will be run in 2.5 hours.

What is a quadratic function?A polynomial function that has one or more variables and a variable having a maximum exponent of two is said to be quadratic. It is also known as the polynomial of degree 2 since the second-degree term is the greatest degree term in a quadratic function. At least one term in a quadratic function must be of the second degree. It has algebraic properties.
Given statements about the x-intercepts of quadratic functions,
the expression of a quadratic function is given by,
ax² + bx + c = 0
the values of x are the zeroes of the quadratic functions, which is also known as the x-intercept.
since the degree of the polynomial is 2 so there will be at least two values for the x-intercept.
the x-intercept is the point on the x coordinate where the value of y is zero.
and let x = a be an x-intercept so the factor of function is (x - a).
Hence options A and E are correct.

The population of a city doubles during the workday. At the end of the workday, the population decreases
by half. If the population of the city is roughly 4,000,000 people before "rush hour," and the morning rush
hour actually lasts 3 hours, what would be the population 12 hours after the start of rush hour if the
population continued to double every 3 hours? People leave the city for home at the same rate as they
come into the city. If there are 8,000,000 people in the city during the workday, what would be the
population 12 hours after the start of the evening rush hour, which lasts 3 hours, if the population continued
to be cut in half every 3 hours?
Answers
The population 12 hours after the start of rush hour, which lasts 3 hours and the population doubles every 3 hours, would be 64,000,000 people. The population 12 hours after the start of the evening rush hour, which lasts 3 hours and the population is cut in half every 3 hours, would be 500,000 people.
Explanation:To calculate the population 12 hours after the start of rush hour, which lasts 3 hours, we need to find the number of doubling periods that occur within that time frame. Since the population doubles every 3 hours, there are 12/3 = 4 doubling periods.
Each doubling period results in the population doubling, so if the population starts at 4,000,000 people, after 4 doubling periods it would be 4,000,000 × 2⁴ = 64,000,000 people.
To calculate the population 12 hours after the start of the evening rush hour, which lasts 3 hours and the population is cut in half every 3 hours, we need to find the number of halving periods that occur within that time frame. Since the population is cut in half every 3 hours, there are 12/3 = 4 halving periods.
Each halving period results in the population being cut in half, so if the population starts at 8,000,000 people, after 4 halving periods it would be 8,000,000 × (1/2)⁴ = 500,000 people.

The graphs of f(x) = 5x and its translation, g(x), are shown on the graph.
On a coordinate plane, 2 exponential functions are shown. f (x) approaches y = 0 in quadrant 2 and increases into quadrant 1. It crosses the y-axis at (0, 1) and goes through (1, 5) and (2, 25). g (x) approaches y = negative 10 in quadrant 2 and increases into quadrant 1. It goes through (0, negative 9), (1, negative 5), (2, 15).
What is the equation of g(x)?
g(x) = 5x – 9
g(x) = 5x – 10
g(x) = 5x – 9
g(x) = 5x – 10
Answers
Answer:
[tex]g(x) = 5^{x} -10[/tex]
Step-by-step explanation:
See the attached figure which represents the problem.
At first we should know the rules of translation
1) {f(x) + a} is f(x) shifted up (a) units
2) {f(x) – a} is f(x) shifted down (a) units
3) {f(x + a)} is f(x) shifted left (a) units.
4) {f(x – a)} is f(x) shifted right (a) units.
The given function : [tex]f(x) = 5^{x}[/tex]
As shown on the attached graph the function g(x) is below f(x)
Which mean f(x) is shifted down.
by comparing two points with the same x-coordinate like (1,5) and (1,-5)
So, the difference will be = 5 - (-5) = 10
by applying the second rule and substitute with a = 10
g(x) = f(x) - 10
[tex]g(x) = 5^{x} -10[/tex]

Answer:
The selected options: 1 , 2 and 5
Step-by-step explanation:
Dilation 2/5 was done on a rectangle, and the center of dilation is V
We will check which of the options is true:
Option 1: The image is a reduction because 0 < n < 1 (True)
Because 2/5 = 0.4 < 1, so, the image will be smaller than the pre-image.
Option 2: The side lengths of the image are two-fifths the size of the corresponding side lengths of the pre-image. (True)
Because pre-image and image are similar so their sides will be proportional, so the pre-image is 2/5 of the image.
Option 3: The angles of the image are two-fifths the size of the angles of the pre-image. (Wrong)
Because the angles of similar rectangles are congruent not proportional.
Option 4: The center of dilation is at point Q. (Wrong)
Because the center of dilation is V.

Ed Employee has weekly earnings of $544.00, and he claims 2 exemptions. How much tax is withheld?
$19.81
$17.56
$18.73
$16.57
Answers
Answer:
17.56
Step-by-step explanation:
The amount of tax withheld from Ed Employee's weekly earnings is approximately $36.02. Option D is the right choice.
To calculate the amount of tax withheld, we need to determine the applicable tax rate based on the employee's weekly earnings and the number of exemptions claimed.
Given:
- Weekly earnings: $544.00
- Number of exemptions claimed: 2
First, let's find the applicable tax rate from the provided table based on the weekly earnings. The table provides tax rates for various income ranges.
Since the weekly earnings fall between $540 and $560, we can interpolate to find the tax rate corresponding to this range.
From the table:
- For earnings between $540 and $560, the tax rate is between $19.81 and $17.56.
Using linear interpolation:
[tex]\[ \text{Tax rate} = \$19.81 - \left( \frac{560 - 544}{560 - 540} \times (\$19.81 - \$17.56) \right) \]\[ = \$19.81 - \left( \frac{16}{20} \times ( \$19.81 - \$17.56 ) \right) \]\[ = \$19.81 - \left( \frac{4}{5} \times \$2.25 \right) \]\[ = \$19.81 - \$1.80 \]\[ = \$18.01 \][/tex]
Now, to find the tax withheld:
[tex]\[ \text{Tax withheld} = \text{Tax rate} \times \text{Number of exemptions} \]\[ = \$18.01 \times 2 \]\[ = \$36.02 \][/tex]
Therefore, the amount of tax withheld from Ed Employee's weekly earnings is approximately $36.02. Option D is the right choice.
Question:-
Ed Employee has weekly earnings of $544.00 and he claims 2 exemptions. How much tax is withheld?
A. $19.81
B. $17.56
C. $18.73
D. $36.02
Complete the following proof.
Given: m ∠XOY = m ∠WOV
m YZ = m ZW
Prove: m XZ = m ZV
Answers
Answer:
Step-by-step explanation:
m ∠XOY = m ∠WOV
so, m XY = m WV --- (i)
{ If angle subtended by two arcs at the center are equal, then length of arc are equal}
m YZ = m ZW ------- (ii) {given}
Add (i) and (ii)
XY + YZ = WV + ZW
XZ = ZV
Hence proved.
Answer:
Given that m ∠XOY = m ∠WOV then m XY = m WV, because central angles are equal to arcs.
Given: m YZ = m ZW
The addition of arcs XY and YZ make arc XZ, that is: m XY + m YZ = m XZ
The addition of arcs ZW and WV make arc XZ, that is: m WV + m ZW = m ZV
Then, m XZ = m ZV

find the values of x and y that make the quadrilateral a parallelogram
Answers
To determine if a quadrilateral is a parallelogram, we need to compare the lengths of the sides and the measures of the angles.
Explanation:A quadrilateral is a parallelogram if and only if both pairs of opposite sides are equal in length and both pairs of opposite angles are congruent. To find the values of x and y that make the quadrilateral a parallelogram, we need to compare the lengths of the sides and the measures of the angles.
For example, if we have a quadrilateral with sides x, y, z, and w, we can check if it is a parallelogram by comparing x and z and y and w. If x = z and y = w, then the quadrilateral is a parallelogram.
Similarly, we can check the angles by comparing the measures of opposite angles. If the measures of the opposite angles are equal, then the quadrilateral is a parallelogram.

The values of x and y that make the quadrilateral a parallelogram are [tex]\(x = 114^\circ\)[/tex] and [tex]\(y = 66^\circ\)[/tex].
In a parallelogram, opposite angles are congruent. Therefore, if one angle measures [tex]\(66^\circ\)[/tex], its opposite angle must also measure [tex]\(66^\circ\).[/tex] Similarly, if another angle measures [tex]\(114^\circ\)[/tex], its opposite angle must also measure [tex]\(114^\circ\)[/tex].
Let's denote the measures of the angles as follows:
- Angle opposite to x is [tex]\(114^\circ\)[/tex]
- Angle opposite to y is [tex]\(66^\circ\)[/tex]
Since the opposite angles are congruent, we have:
[tex]\[ x = 114^\circ \]\[ y = 66^\circ \][/tex]
Therefore, the values of x and y that make the quadrilateral a parallelogram are [tex]\(x = 114^\circ\)[/tex] and [tex]\(y = 66^\circ\)[/tex].

The missing numbers in the sequence are 10 and 17. The complete sequence is 8, 10, 15, 20, 26, 33, 17, following an alternating difference pattern.
To find the missing numbers in the sequence, let's observe the pattern between the given numbers:
8, __, 15, 20, 26, 33, __
Looking at the differences between consecutive terms, we notice the following pattern:
15 - 8 = 7
20 - 15 = 5
26 - 20 = 6
33 - 26 = 7
We see that the differences alternate between 7 and 5. So, following this pattern, the missing numbers should continue this alternating difference.
The missing numbers are:
8 + 7 = 15
15 - 5 = 10
10 + 7 = 17
So, the missing numbers are 10 and 17.
Therefore, the sequence is: 8, 10, 15, 20, 26, 33, 17.

Jordan can type 240 words in 5 minutes, based on her typing speed of 48 words per minute.
Jordan can type 96 words in 2 minutes. To find out how many words she can type in 5 minutes, we need to calculate her typing speed per minute and then multiply it by 5 minutes. First, we find the typing speed per minute:
Speed = Total words / Total time = [tex]\frac{96}{2}[/tex] = 48 words per minute.
Now, we multiply this speed by 5 minutes to find out how many words Jordan can type in that time:
5 minutes x 48 words/minute = 240 words.
So, Jordan can type 240 words in 5 minutes.

You can interpret this equation as proportion.
Cross multiply:
[tex]3(3x+2)=5(2x-1)\\ \\9x+6=10x-5\ [\text{Use distributive property}]\\ \\9x-10x=-5-6\\ \\-x=-11\\ \\x=11[/tex]
Final answer:
The rational equation (3x + 2)/5 = (2x - 1)/3 simplifies to 9x + 6 = 10x - 5, which further simplifies to x = 11 after rearranging and combining like terms.
Explanation:
To solve the rational equation (3x + 2)/5 = (2x - 1)/3, we first find a common denominator to eliminate the fractions. Multiplying each side of the equation by the common denominator of 15, we get 9x + 6 = 10x - 5. Subtracting 9x from both sides and adding 5 gives us x = 11. Therefore, the correct solution to the given equation is x = 11.
