E(x) = A(x) - S(x) = 2400x + 40x^2 - (250x + 500) = 2400x + 40x^2 - 250x - 500 = 40x^2 + 2150x - 500
Ashton's expenses for 3 years E(3) = 40(3)^2 + 2150(3) - 500 = 40(9) + 6450 - 500 = 360 + 5950 = $6,310
Answer:
i would make a number line up to 10. the with a hollow dot on -4 have a line facing left
It really does not matter, I tend to solve for x first simply because it comes before y, but you do whatever is easier for you.
Answer:
f(2a−1)=7a−13
7(2a−1) − 13
14a − 7 − 13
14a − 20
Step-by-step explanation:
replace a with f(2a − 1)
distribute the bracket
combine -7 and -13 because they are the like terms here.
