Step-by-step explanation:
<u>y</u> - <u>4</u> = -4
x - 6
y - 4 = -4x + 24
y = -4x + 24 + 4
y = -4x + 28
For
|a|>15
assume
a>15
a<-15
so
x+6>15
minus 6
x>9
x+6<-15
minu 6
x<-21
B is answer
Answer:
<em>(1, 7) </em>
Step-by-step explanation:
y = 3x + 4
y = 6x + 1
6x + 1 = 3x + 4 ⇒ x = 1
y = 3(1) + 4 = 7
<em>(1, 7)</em>
You could first solve for y, assuming x is 0, and y = 6. Then solve for x, and that means y = 4.
