Answer:
x = -9
Step-by-step explanation:
6x + 6 = 3x – 21
Subtract 3x from each side
6x-3x + 6 = 3x-3x – 21
3x+6 = -21
Subtract 6 from each side
3x+6-6 = -21-6
3x = -27
Divide by 3
3x/3 = -27/3
x = -9
Step-by-step explanation:
Use a Table of Values to Graph the Equation y =3x+1. y=3x+1 y = 3 x + 1. Substitute −2 - 2 for x x and find the result for y y . y=3(−2)+1 y

To find the range we need to find the vertex of the parabola which is at (-b/2a , y)
-b/2a would be 2/2 = 1 ... so find the y value at x = 1
12 - 2(1) - 15 = 1-17 = -16
So the vertex is at (1,-16)
Since the parabola opens upward from that point the minimum value of the range is y = -16
The range would include the point -16 so it is actually
R = [-16,infinity)
