The answer is y=-4x-13. first you need to find b (the y-intercept). to do that you plug in the values to y=mx+b so it is -5=-4(-2)+b. when you solve for b you get -13. then you write y=mx+bas you normally would so you would get y=-4x-13. hope this helped :)

This table shows a proportional relationship between the number of cups of sugar and flour used for a recipe.
inna [77]

To find the answer for one cup of flour, divide the cups of sugar by the cups of flour. Here’s how it works.

Since we want the proportion for 1 cup of flour, we divide it by itself to get 1.

Thus, we need to have equal sides, so we divide the number of cups of sugar by the amount the cups of flour divided by.

So: 2.5/7.5=1/3

1 cup of flour is proportional to 1/3 cups of sugar.

Hope this helps!

Step-by-step explanation:

Hello,

2(a+b+c)=(a+b)+(b+c)+(c+a)=4+5+7=16\\\\\text{*** divide by 2 both sides ***}\\\\(a+b+c)=\dfrac{16}{2}=8 \ \ \text{ so...}\\\\(a+b+c)^2=8^2=\large \boxed{64}

Hope this helps.
