Answer:
y - w + x
Step-by-step explanation:
y = w + v - x
or y - w + x = w + v - x - w + x [adding x and subtracting w from both sides]
or y - w + x = v
Therefore, v = y - w + x
Answer:
There are no restrictions on x, so the domain is (-∞,∞)
When x = 2, 5|x - 2| = 0, so the range is [4,∞)
Step-by-step explanation:
Answer:
x = -5
Step-by-step explanation:
0.2x-8=0.4x-7
First, add 8 to both sides.
0.2x-8+8=0.4x-7+8
0.2x=0.4x-1
Next, subtract 0.4x from both sides.
0.2x-0.4x=0.4x-1-0.4x
-0.2x=1
Divide both sides by -0.2:
-0.2x/-0.2=1/-0.2
x=-5
