Answer:
5, 9
Step-by-step explanation:
let
x= first number
y = second number
x- y= 4( equation 1)
xy=45( equation 2)
From equation 1
x= 4+y( equation 3)
put equation 3 into equation 2
( 4+y)y=45
4y+y^2=45
( y-5)(y+9)=0
y=5,-9
Then put y=5 into equation 3
x=9
Hey there! :)
Answer:
f(-2) = -148.
Step-by-step explanation:
To calculate f(-2), simplify substitute -2 for x in the equation. Therefore:
f(x) = 4x³ -12x² + 40x + 12
Becomes:
f(-2) = 4(-2)³ - 12(-2)² + 40(-2) + 12
Simplify:
f(-2) = 4(-8) - 12(4) - 80 + 12
f(-2) = -32 - 48 -80 + 12
Finally, you get:
f(-2) = -148.
