What points are solutions to the equation 3x-4y-8=12

ikadub [295]

Answer:

x = 6.67

Step-by-step explanation:

Rewrite the equation:

-4y = -3x +20

y = $\frac{3}{4} x-5$

Find where y = 0

0 = $\frac{3}{4} x -5$

5 = $\frac{3}{4} x$

x = 6.67

Hope it helps! (:

Explain why the graph of the equation g(x) = -(x + 1 ) - 3 would be a parabola opening downward.

sashaice [31]

Answer: Because the a-value is negative.

<u>Step-by-step explanation:</u>

The vertex form of a quadratic equation is: y = a(x - h)² + k where

"a" is the vertical stretch
-a is a reflection over the x-axis
h is the horizontal shift (positive = right, negative = left)
k is the vertical shift (positive = up, negative = down)

Given: g(x) = - (x + 1)² - 3

↓

a= -1

Since the a-value is negative, the parabola will be reflected over the x-axis which will change the curve from (U-shaped) to (∩-shaped).
