Is the ordered pair (1,-2) a solution to the equation 3x + 4y=-11

no

Step-by-step explanation:

if you plug it in...

3(1)+4(-2)=-11

4+-8=-11

4-8=-11

-12 does NOT equal -11

so the answer is no

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3

answer: 414,377,008

step-by-step explanation:

just multiply it
