Answer:
The right answer is : f(-4)=5
Combine like terms:
subtract x from both sides to get
2x+5=14
subtract 5
2x=9
isolate x:
divide 2 from both sides to isolate x
x=9/2
that's your final answer. unless your teacher wants you to put it in decimal form in which all you do is divide 9÷2.

It's a rotation
Answer:
C
Step-by-step explanation:
The solution is the dot where the two equations meet, so that's why I compared them. You can also see it in the graph itself.
Answer:
x = 1
Step-by-step explanation:
2x + 8 = 4x + 6
<em>subtract 6 from both sides of the equation</em>
2x + 8 - 6 = 4x + 6 - 6
2x + 2 = 4x
<em>subtract 2x from both sides of the equation</em>
2x - 2x + 2 = 4x - 2x
2 = 4x - 2x
2 = 2x
<em>divide both sides of the equation by 2</em>
2/2 = 2x/2
1 = x
