Another way to ask this question: where the x-value of function g equals 12, what's the y-value?
remember that function notation is like so: f(x), g(x), h(x)... so the number in the parentheses is an x-value from the function.
look through your points and find the one that represents an x-value of 12. (12, 19) is the point, and 19 is your output--so, g(12) = 19.
$5. Subtract the cost of the magazine, $3, from the total cost, $28. Now you have $25 then you divide it by the amount of notebooks you have.
2(2d+4)=-3(d+2)
4d+8=-3d-6
4d+3d=-6-8
7d=-14
d=-14/7
d=-2
STEP 1) 7x+10x+12x= 232 STEP 2) 29x = 232 STEP 3) divide 232 by 29 STEP 4) x=8 STEP 5) 7 times 8 = 56, 10 times 8 = 80, 12 times 8 = 96. the highest score was a 96
