Answer:
Step-by-step explanation:
Essentially, begin by flipping the x and y terms:
x = (1 - 2y)^2 + 5
Then, solve for y:

Because we know there is only 1 y-value for any given x-value, the inverse of the given function is also a function.
Answer:
Yup, 27 is correct!
Step-by-step explanation:
5(7)-8
= 35 - 8
= 27
2 1/2 yds = 2.5 x 36 = 90 inches...what she started with
2 ft 8 in = 2(12) + 8 = 32 inches...what she had left
90 - x = 32
90 - 32 = x
x = 58 inches....so she used 58 inches
Simplifying it would make it 3/4b^2. I can't write it down the correct way, but it's three over four times b squared. Unless it's a square root, then things would be different.
1 ton = 2000 ponds
Multiply: 2000x30=?
2000x30=60000
Hope that helped:)
