Answer:
2x
Step-by-step explanation:
x*1=x
then add x. you get 2x.
divide by 1 and you get 2x
Answer:
y = - x - 7
Step-by-step explanation:
Parallel lines have equal slopes.
Calculate the slope m of the given line using the slope formula
m =
with (x₁, y₁ ) = (0, 2) and (x₂, y₂ ) = (3, - 2) ← 2 points on the line
m = = - , thus
y = - x + c ← is the partial equation
To find c substitute P(- 3, - 3) into the partial equation
- 3 = 4 + c ⇒ c = - 3 - 4 = - 7
y = - x - 7 ← equation of parallel line
Your correct answer is: 2y^3+28y-12
Let's simplify step-by-step.
6y3+17y−3−(4y3−11y+9)
Distribute the Negative Sign:
=6y3+17y−3+−1(4y3−11y+9)
=6y3+17y+−3+−1(4y3)+−1(−11y)+(−1)(9)
=6y3+17y+−3+−4y3+11y+−9
Combine Like Terms:
=6y3+17y+−3+−4y3+11y+−9
=(6y3+−4y3)+(17y+11y)+(−3+−9)
=2y3+28y+−12
Answer:
=2y3+28y−12
I'm sorry. I can't explain how I got it. But use

It helps explain it and tells you the answer. Sprry, but hope it helps. It's a website and app.
