Solve the equation for both -1 and 1 first.
50(1/2)^-1 = 100
50(1/2)^1 = 25
Now subtract the two answers and divide by 2 ( -1 to 1 is 2)
75/2 = 37.5
Because the answer got smaller from -1 to 1, the change would be negative.
The rate of change would be -37.5
W + y + v + 88 = 180
22 + y + 43 + 88 = 180
y = 27
Answer:
Hi there!
The answer to this question is: 6x+3
Step-by-step explanation:
Step 1: combine alike terms
in the equation there are two numbers that end with x: 8x and -2x
you simply add them together to get 6x
Step 2: combine numbers
in this equations there are two numbers: 7 and -4
you simply add them together to get 3
Then your final answer should be 6x+3
