Because -2 times -2 is 4 and 2 x 2 is 4 as well. So you cant have -4.
But if you have cube root of -8, you can do -2 as -2 x -2 gives you 4, if you x this by -2 you get -8
Answer:
16 miles an hour
Step-by-step explanation:
40 / 2.5 = unit rate
16.875=ab^3 (divided by what follows)
7.5=ab^1 gives you:
2.25=b^2
b=1.5 now we can solve for a...
7.5=a(1.5^1), a=5 so the function is:
y=5(1.5^x)
