Y = 4x + 4
-8x + 3y = 5
-8x + 3(4x + 4) = 5
-8x + 12x + 12 = 5
-8x + 12x = 5 - 12
4x = -7
x = -7/4
y = 4x + 4
y = 4(-7/4) + 4
y = -7 + 4
y = -3
solution is (-7/4,-3)
Answer:
D
Step-by-step explanation:
The graph above is your graph.
As <em>x</em><em> </em>increase, <em>y</em> decreases
As <em>x</em> decrease, <em>y</em> increases.
However, there is a small portion of the graph where both <em>x</em><em> </em>and <em>y</em><em> </em><em>were</em><em> </em><em>positive</em><em>.</em><em> </em>
But I'm guessing it should be D.
<span>3x+6+5x+4=90
Combine like terms
8x + 10=90
Subtract 10 from both sides
8x=80
Divide 8 on both sides
Final Answer: x= 10</span>
