It’s y=3x

All the other ones, have a y-intercept, therefore it will not start at the origin (0,0)

In order for an equation to be proportional, the equation does not need a y-intercept, it only needs a constant.

Hope this helped! If any questions, feel free to ask! :)

multiply the numbers.

4 x 6 + y = 20

move constant (24) to the right side and change its sign.

24 + y = 20

calculate the difference and you get the answer.

y = 20 - 24

y = -4

So the value of y is -4.

Answer:

The scale factor of the dilation is 2

Step-by-step explanation:

KLMN ~ STUV

$\frac{ST}{KL} = \frac{TU}{LM} =\frac{UV}{MN} =\frac{VS}{NK} =\frac{12}{6} = 2$

The scale factor of the dilation is 2

Answer:

170 m³

Step-by-step explanation:

To solve this type of problem, assume you have two solids joined together to make the shape you have up there. This will enable you find the volume of each, then sum both volume together to get your answer.

Let's solve for the volume as follows.

If we divide the solid into 2, what we have is 2 cuboid: the first having dimensions of:

length (l) = 6m,

width (w) = 2m,

height (h) = 8m

Volume of the first cuboid = $l*w*h = 6*2*8 = 86 m^3$
