Answer:

- 1 = 16 + 3x - 1 \\ 3x = 16 - 1 + 1 \\  \frac{3x}{3} =  \frac{16}{3}  \\  x = 5.33

How to find the limit of that question

Factor the numerator using difference of cubes:
a^3 - b^3 = (a-b)(a^2 +ab+b^2)
a = x
b = 2

\frac{x^3 - 8}{x-2} = \frac{(x-2)(x^2 +2x+4)}{x-2} = x^2 +2x+4

Now you can evaluate limit as x=2.
\lim_{x \to 2} (x^2 +2x+4) = 2^2 +2(2)+4 = 12

“Stephen attempted to use the elimination method to solve the system of equations below but he made a mistake. What is it?
Sladkaya [172]

Answer:

second option

Step-by-step explanation:

x + y = 18 → (1)

4x - 3y = - 12 → (2)

Multiplying (1) by - 4 and adding to (2) will eliminate the x- term

- 4x - 4y = - 72 → (3)

add (2) and (3) term by term to eliminate x

0 - 7y = - 84

- 7y = - 84 ( divide both sides by - 7 )

y = 12

Substitute y = 12 into (1) and solve for x

x + 12 = 18 ( subtract 12 from both sides )

x = 6

solution is x = 6, y = 12
