-5=3/4x-2 solve for x and please show your work!

Nookie1986 [14]

-5 = $\frac{3}{4} x$ - 2 equals x = -4.

First, simplify $\frac{3}{4} x$ to $\frac{3x}{4}$ . / Your problem should look like: -5 = $\frac{3x}{4}$ - 2.
Second, multiply both sides by 4. / Your problem should look like: -20 = 3x -8.
Third, add 8 to both sides. / Your problem should look like: -20 + 8 = 3x.
Fourth, simplify -20 + 8 to -12. / Your problem should look like: -12 = 3x.
Fifth, divide both sides by 3. / Your problem should look like: $- \frac{12}{3}$ = x.
Sixth, simplify $\frac{12}{3}$ to 4. / Your problem should look like: -4 = x.
Seventh, switch sides. / Your problem should look like: x = -4, which is your answer.

1.) p^2+14p-38=0<br> what the vertex?

Lelu [443]

Answer:

vertex = (- 7, - 87)

Step-by-step explanation:

given a parabola in standard form : ax² + bx + c : a ≠ 0

Then the x- coordinate of the vertex is

$x_{vertex}$ = - $\frac{b}{2a}$
