Given the point and it''s image, determine the scale factor. A (3, 6) A'' (4.5, 9) G'' (3, 6) G (1.5, 3) B (2, 5) B'' (1, 2.5).

Put the value of the letters with " over the original
So for A we have 3 in the front and 4.5 for A"
4.5/3 = 1.5
We can check if this is actually the scale factor but using the other numbers
The second numbers for A and A" are 6 and 9
6 * 1.5 = 9
So for point A it is 1.5
Use the same thing for G. That gives you 2
For B, you get 0.5
So the scale factors are 1.5, 2, and 0.5

Given the line below.

Grace [21]

Answer:

$y+2=(x+2)$

Step-by-step explanation:

<u><em>The picture of the question in the attached figure</em></u>

step 1

Find the slope

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

we have

(-2,-2) and (2,2)

substitute the values

$m=\frac{2+2}{2+2}=1$

step 2

Find the equation of the line in point slope form

$y-y1=m(x-x1)$

we have

$m=1\\(x1,y1)=(-2,-2)$

substitute

$y-(-2)=(1)(x-(-2))$

$y+2=(x+2)$

Jose works as a salesperson at an electronics store and sells phones and phone accessories. Jose earns a $9 commission for every

Yanka [14]

Answer:

Let p be the number of phones sold and a be the number of accessory sold.

9p + 4a = 253

a - p = 8

Step-by-step explanation:

He gets $9 for every phone and $4 for every accessory, so you can write this as

9p + 4a

Then he made a total of $253 do the new equation is

9p + 4a = 253

We are also given that he sold 8 more accessories than phones. So we can write this as

a = p + 8

rearrange that so that all the variables are to one side.

a - p = 8

Now you have the two equations needed to solve the for the variable. The question didn't ask me to solve for the variable so I'll leave it here.

Margaret [11]

Answer:

y-18=-6(x+3)

Step-by-step explanation:

y-y1=m(x-x1)

m=-6

y-18=-6(x-(-3))

y-18=-6(x+3)
