brett is joining a new gym. he can join power plus or heavy hulk. at power plus, it will cost $34.14 per month, plus a sign-up fee of $20.00. at heavy hulk, it will cost $34.39, plus a sign-up fee of $32.50. right now, heavy hulk is cutting their sign-up fee in half for new members. if brett signs up at a gym today, after how many months will the cost of the memberships be the same?

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation

twenty-six miles over two gallons because the proportion for the original 13 miles to one gallon would be written 13/1 and, doing the same thing to the top and bottom, i multiplied by 2 and got 26/2

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function

the square root of 16 is 4.

4*4 = 16
