I'm pretty sure that it would be 1/2 since it says 1/3 each whole, which in this case it would be 1/3 each hour.

Please help me with this math question!

The bases are both 2, so we would subtract the exponents. This is because the rule is

(a^b)/(a^c) = a^(b-c)

In this case,
a = 2
b = 3/4
c = 1/2

So this means
b - c = (3/4) - (1/2) = (3/4) - (2/4) = 1/4

After subtracting the exponents, the final exponent is 1/4

So the expression simplifies to 2^(1/4) which is the same as \sqrt[4]{2} (fourth root of 2)

Write an equation that is parallel to y=-5/2x-5
NeX [460]

       A parallel equation (when graphed) will have the same slope, but a different y-intercept.

       As long as you keep y = -\frac{5}{2}x + b, you can input anything for b to solve this question.

       Given:

y = -\frac{5}{2}x - 5

       Equation of a parallel line:

y = -\frac{5}{2}x + 6, y = -\frac{5}{2}x + 1,356, y = -\frac{5}{2}x - 8, etc

     Example answer you can use:

             y = -\frac{5}{2}x - 8
