= 3(4a^2 + 4a - 3) - 4a^2 + 28
= 12a^2 + 12a - 9 - 4a^2 + 28
= 8a^2 + 12a + 19
= 4a(2a + 3) + 19
Answer:
x = - 3
Step-by-step explanation:
6x + 12 = - 6
6x = - 18
x = - 3
7.1+m
Or if you needed to add a variable to be the answer it would be 7.1+m=x
Answer:
Step-by-step explanation:
<u>The line has a positive slope and negative y-intercept.</u>
This is only matched by a choice C
Answer:
y = 2x - 9
Step-by-step explanation:
y= mx + b
plug in slope
y = 2x + b
plug in points
1 = 2 (5) + b
simplify
1 = 10 + b
subtract 10 each side
-9 = b
plug in to original equation
y=2x - 9
