I'm assuming the given function is f(x) = 15x^2 + 10x.

If so, then,

f(x) = 15x^2 + 10x
f(x) = 15*(x)^2 + 10*(x)
f(-1) = 15*(-1)^2 + 10*(-1) ... note how x is replaced with -1
f(-1) = 15*(1) + 10*(-1)
f(-1) = 15 - 10
f(-1) = 5

Therefore the answer is 5

Solve the following equation given x=-2 and y=8

Naya [18.7K]

the answer would be 3 because 8 + (-2) is the same as subtraction so you would get 6 from that and dividing it by 2 would make it 3, I hope this helps
