Step-by-step explanation:

Translation

For the translation find the distance between corresponding points of A and A'. It is 5 units.

Dilation

We see the figures A' and A'' are symmetrical and the sides on the x-axis overlap. It means the center of dilation is the origin, the point (0, 0).

Find the scale factor by dividing the corresponding x- or y- coordinate of A'' to the one of A'.

Take points (-2, 0) of A' and (-3, 0) of A''.

The scale factor is:

what is the slope of (29,11) and (-3,-7)

Answers

Answer:

The slope is [tex]\frac{9}{16}[/tex]

Step-by-step explanation:

Hi there!

We are given the points (29, 11) and (-3, -7), and we want to find the slope of them.

The slope can be calculated from two points with the slope formula, which is [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points.

We have two points given, but let's label their values to avoid any confusion when we actually calculate:

[tex]x_1=29\\y_1=11\\x_2=-3\\y_2=-7[/tex]

Now substitute into the formula (m is the slope).

m=[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

m=[tex]\frac{-7-11}{-3-29}[/tex]

Subtract

m=[tex]\frac{-18}{-32}[/tex]

Reduce the fraction

m=[tex]\frac{9}{16}[/tex]

The slope is [tex]\frac{9}{16}[/tex]

6th grade students took a survey on their favorite subject.
The ratio of students whose favorite subject was Science to
students whose favorite subject was Math was 3:5. If 238
more students picked Math as their favorite subject, how many
students picked Science as their favorite subject?

Answers

Using a system of equations, it is found that 595 students picked Science as their favorite subject.

For our system, we suppose that x is the number of students that picked science, and y is the number of students that picked math.

Ratio of science to math of 3:5, thus:

[tex]\frac{x}{y} = \frac{3}{5}[/tex]

Then

[tex]5x = 3y[/tex]

[tex]x = \frac{3y}{5}[/tex]

238  more students picked Math as their favorite subject, thus:

[tex]y = 238 + x[/tex]

[tex]y - \frac{3y}{5} = 238[/tex]

[tex]\frac{2y}{5} = 238[/tex]

[tex]y = \frac{238(5)}{2}[/tex]

[tex]y = 595[/tex]

595 students picked Science as their favorite subject.

MULTIPLE CHOICE:

Jen and David owe $21,000 in loans for their two cars. The amount of the loan for Jen's car is $2,000 less than twice the amount of the loan for David's car. How much is each car loan? (Let j represent the amount of Jen's loan and let d represent the amount of David's loan.)


A. d + j = 21,000
2d − 2,000 = j


B. j + d = 21,000
2j − 2,000 = d



C. j + d = 21,000
2j + 23,000 = d


D. j + d = 2,000
2j − 21,000 = d


E. d + j = 2,000
2d − 21,000 = j

Answers

9514 1404 393

Answer:

  A. d + j = 21,000; 2d − 2,000 = j

  d = $7,666.67; j = $13,333.33

Step-by-step explanation:

The relationships given in the problem statement are ...

  d + j = 21,000 . . . . .  the total of the two loans is $21,000

  2d -2000 = j . . . . . . Jen's is $2000 less than twice David's

__

These equations can be solved by substituting for j:

  d +(2d -2000) = 21000

  3d = 23000 . . . . . . . . . . . add 2000, collect terms

  d = 23000/3 = 7666.67 . . . divide by the coefficient of d

  j = 21000 -d = 21000 -7666.67 = 13333.33

Jen's loan is $13,333.33; David's loan is $7,666.67.

A figure has been dilated from center O by a scale factor of r = 3/10 scale factor would magnify the dilated figure back to the original size?​

Answers

Answer: The new scale factor needs to be 10/3

Explanation:

Consider a line segment that is 10 units long. Apply the scale factor 3/10 to it, and now it's 3 units long because (3/10)*10 = 3.

To get it back to 10 units, we multiply by the scale factor 10/3 which is the reciprocal of the original scale factor. Note that (3/10)*(10/3) = 1. Those two scale factors multiply to 1 to indicate no change has been made overall.

Step-by-step explanation:

or, 2x - x = -1 -31 + X -1

The congruent angles each measure
pls help

Answers

Answer:

Each of the congruent angles is 34

Step-by-step explanation:

A = 112                               A is the given angle

A + x + x = 180                   A + x + x = 180 All triangles have 180 degrees  

112 + x + x = 180                 Combine

112 + 2x = 180                     Subtract 112 from both sides

112-112 + 2x = 180 - 112       Combine

2x = 68                                Divide both sides by 2

2x/2 = 68/2

x = 34

Move the decimal point in 407.26 three places to the left = 0.407283

Step-by-step explanation:

Answer:

3, left

Step-by-step explanation:

When you're dividing a number by any power of 10 that is a whole number (10, 100, 1000, etc.), you move the decimal point to the left as many times as there are zeroes in the digit.

Examples:

30.22 ÷ 100 = 0.3022

There are two zeroes in 100, so move the decimal point two spaces to the left.

568.9 ÷ 10000 = 0.05689

There are four zeroes in 10000, so move the decimal point four spaces to the left.

The given equation in the problem is 407.26 ÷ 1000, so you move the decimal point 3 spaces to the left to find the correct answer.
