Answer:

x = - 3 and x = 1

Step-by-step explanation:

4x - 2 - 2x = x - 5, that is

2x - 2 = x - 5 ( subtract x from both sides )

x - 2 = - 5 ( add 2 to both sides )

x = - 3

----------------------------------------

- (x + 3) = 2x - 6 ← distribute left side

- x - 3 = 2x - 6 ( subtract 2x from both sides )

- 3x - 3 = - 6 ( add 3 to both sides )

- 3x = - 3 ( divide both sides by - 3 )

x = 1

Answer:

1) Combine like terms

2) $\sqrt[3]{x} =3$

3) cube both sides of the equation

4) $4\sqrt[3]{27} +8\sqrt[3]{27}=36$

5) 4(3) + 8(3) = 36

Step-by-step explanation:

1) Combine like terms

2) $\sqrt[3]{x} =3$

3) cube both sides of the equation

4) $4\sqrt[3]{27} +8\sqrt[3]{27}=36$

5) 4(3) + 8(3) = 36

What is the midpoint of (-23,-14) and (-18,2)

zloy xaker [14]

Given two coordinates point 1 as (-23,-14) and point 2 as(-18,2).

To find the midpoint we would use the formula below;

$\text{midpoint(x,y)}=(\frac{x_1+x_2_{}_{}}{2},\frac{y_1+y_2}{2})$

Where x1=-23, x2=-18, y1=-14, y2=2

We would substitute the values into the midpoint formula.

$\begin{gathered} \text{midpoint =(}\frac{-23-18}{2},\frac{-14+2}{2}) \\ =(-\frac{41}{2},-6) \end{gathered}$

Therefore, the answer is

$\text{midpoint}=(-\frac{41}{2},-6)$
