Answer:
A: 5
B: 6
C: 3x^2 - 2x
D: 8
E: 22
Step-by-step explanation:
A: (-1)^2 + 4 = 5
B: (-4)^2 +4 = 16
2 x (-3) -4 = -10,
16-10=6
C: 3(x^2 + 4) = 3x^2 + 12
3x^2 + 12 -2x -4, simplify
3x^2 - 2x
D: g(3) = 2*3 -4 = 2
f(2) = 2^2 +4 = 8
E: f(3) = 3^2 + 4 = 13
g(13) = 2*13 - 4 = 22
Answer: x=3y+6
Explanation to solve:
You must move all terms not containing x to the right side of the equation!
Answer: Answer :Isolate the variable by dividing each side by factors that don't contain the variable.

Step-by-step explanation:
Answer:
34, 35, 36
Step-by-step explanation:
1st number = x
2nd number = x+1
3rd number = x+2
So the equation would be:
x+2(x+1)+(x+2)-7=133
x+2x+2+x+2-7=133
4x-3=133
4x=136
x=34
Answer:
0
Step-by-step explanation:
f(x) = y
To find f(2), it means to find the value of y when x = 2.
From the graph, when x = 2, the corresponding y-coordinate = 0.
Therefore,
f(2) = 0
