Answer:
3x+8
Step-by-step explanation:
First, distribute the 2 across the parenthesis.
10-3v+9v=28
Combine like terms on the left.
10+6v=28
Start to get the numbers on the right and the v alone on the left by moving the 10 to the right.
6v=28-10
6v=18
Divide to get the v alone.
v=3
Hope that helps.
For slope m and point (x₁, y₁), the point-slope equation of the line can be written as
y -y₁ = m(x -x₁)
You have m = -4 and (x₁, y₁) = (4, -9), so the equation of your line is
D. y+9 = -4(x-4)
I. H o p e It. R I g h t.
(x - 9) (x-3)

Answer: Choice C. (2x - 6i)(x + 3i)</h3>
Work Shown:
2x^2 + 18
2(x^2 + 9)
2(x - 3i)(x + 3i) .... see note below
(2x - 6i)(x + 3i)
Note: I used the rule that a^2 + b^2 = (a - bi)(a + bi). I recommend FOILing out the right hand side to confirm the equation is true. You'll use the idea that i^2 = -1.
