2x + 5 =7
Subtracting 5 from both sides
= 2x +5-5 = 7-5
=2x = 2
= x = 2/2
=x = 1
You multiply each point by 1/2 or 0.5 so if you have point A which is at (15,-3) it would become (7.5,-1.5) and you graph it there
He would buy 5 because 5 cd's cost 50 dollars and the shipping and handling is an extra 4$
Step-by-step explanation:
step 1. I assume i is imaginary
step 2. i^2 = -1, i^3 = -i, i^4 = 1, i^5 = I. . . . and so on
step 3. i - 1 - i + 1 + i - 1 - i + 1 + i - 1
step 4. the result is i - 1.
