Oh how fun, functions!! You substitute f(-2) into your starting function so it will look like this:
f(x)=2(5x+7)
f(x)=10x+14
f(-2)=10(-2)+14
f(-2)=(-20)+14
f(-2)=(-6)
divide by negative 2 on each side to find f:
f=3
Hope this helped!!
The ratio is (saturated fat) : (total fat) -----
6 grams : 9 grams -----
Divide both sides by 3 -----
6/3 grams : 9/3 grams -----
2 grams : 3 grams -----
2:3 is the ratio -----
You can also represent it in fraction form : 2/3
Y= 2/3x + b
12= 2/3(9) + b
12= 6 + b
6 =b
Anwer: y= 2/3x + 6
