In the diagram, ARST-

antiseptic1488 [7]

Answer:

The scale factor is 4.5

Step-by-step explanation:

Scale factor from ∆RST to ∆XYZ = side length of ∆XYZ / corresponding side length of ∆RST

Thus:

XY corresponds to RS

XY = 45

RS = 10

Therefore:

Scale factor = 45/10 = 4.5

Scale factor from ∆RST to ∆XYZ = 4.5

Write a function rule for the table

Ghella [55]

Answer:

Step-by-step explanation:

Recall the slope is change of y over change of x which in this case the change in x is 1 while the change in y is 2 since the $y$ 's are going up by 2 while the $x$ 's are going up by 1.

So the slope is 2.

The one equation with slope 2 is D.

The answer is most likely D.

Let's check.

$f(x)=2x$

$y=2x$

$y=2(-3)=-6$ while $x=-3$ .

$y=2(-2)=-4$ while $x=-2$ .

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

$y=2(0)=0$ while $x=0$ .

Also notice the $x$ is doubled (multiplied by 2) to get $y$ .
