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
1 hour = 70 miles
3 hours = 70 x 3
= 210 miles
The answer would be 210 miles.
Answer:
y= −1 + x/3
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Factorization: (x + 4)∧2=0
Solutions based on Factorization: x + 4 = 0 ⇒ X∨1 = X∨2 = -4
