Answer: 6 = 6
Step-by-step explanation:
The sum of 5 times a number and -8:
5x - 8 = y
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).
Answer:
15
Step-by-step explanation:
5x + 2 = 77
5x = 77 - 2
5x = 75
5x/5 = 75/5
x = 15
