Answer:
Step-by-step explanation:
(g-f)(x) = 9x³ - 4x² + 10x - 55 - [ 4x³ +3x² - 5x + 20]
To remove the parenthesis, take - inside, multiply f(x) by -1
= 9x³ - 4x² + 10x - 55 - 4x³ - 3x² + 5x - 20
Now, bring like terms together,
= 9x³ - 4x³ - 4x² - 3x² + 10x + 5x - 55 - 20
= 5x³ - 7x² + 15x - 75

Step-by-step explanation:
Let's solve for y.
9x+6y=27
Step 1: Add -9x to both sides.
9x+6y+−9x=27+−9x
6y=−9x+27
Step 2: Divide both sides by 6.
6y
/6=−9x+27
