1. C. 7*1=7
2. B. 10x+0=10x
Its true you are doing it to both side. If you only one side, then the inequality would not be true. Subtract is like adding the negative . number, so you still would have to do it to both side of the inequality so the inequality is true,
Answer: -3
Explanation: In this problem, we're given the function f(x) = 2x + 1 and we're asked to find f(-2).
To find f(-2) or the value of the function or the value of the function when <em>x = -2</em>, we simply substitute -2 in for <em>x</em> in our function.
So we have f(-2) = 2(-2) + 1 or -4 + 1 which equals -3.
So f(-2) or the value of the function when x = -3 is -3.
Answer: x = 17
Step-by-step explanation:
2+x = 2x-15
subtract x on both sides
2 = x -15
add 15 to both sides
17 = x
------------------
17+2 = 2(17)-15
19 = 34 -15
19 = 19
