Answer:
D. add 4x to both sides

Explanation:
-9x = -4x + 5
+ 4x + 4x
-5x = 5

-4x and -4x are opposite terms, so they cancel each other out.
Once you add 4x to both sides, the variable term (-5x) is isolated on one side of the equation.

( -7v 4 - 5v ) - ( -5v 3 - 2v ) + ( -7v - 6v 4 - 4v 3 ) simplified

Answer:

-13v^4 + v^3 - 10v (if simplified)

Step-by-step explanation:

combine like terms

(-7v^4 - 5v) - (-5v^3 - 2v)+ ( - 7v - 6v^4 - 4v^3)

-7v^4 + -6v^4 = -13v^4

-5v^3 + -4v^3 = v^3 (the five becomes positive because of the negative sign infront of the parenthesis) Example: -(-5v^3) = +5v^3

-13v^4 + v^3 -5v -(-2v) -7v (now we have the -2 left alone in the parenthesis which means it becomes positive too) Example: -(-2v) = +2v

-5v +2v - 7v = -3v -7v = -10v

Answer: -13v^4 + v^3 - 10v

Midpoint Formula: $\displaystyle (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})$

Step-by-step explanation:

<u>Step 1: Define</u>

Point A(8, 2) → x₁ = 8, y₁ = 2

Point B(3, 8) → x₂ = 3, y₂ = 8

<u>Step 2: Find Midpoint</u>

Simply plug in your coordinates into the midpoint formula to find midpoint

Substitute in points [Midpoint Formula]: $\displaystyle (\frac{8+3}{2},\frac{2+8}{2})$
[Midpoint] [Fraction] Add: $\displaystyle (\frac{11}{2},\frac{10}{2})$
[Midpoint] Divide: $\displaystyle (\frac{11}{2},5)$
