Answer:
-10
Step-by-step explanation:
Assuming that x-2=-5, we can subtitute it into the equation as follows:
(-5)^2 + 5(-5) - 10, we start off with the exponent according to the order of operations resulting in:
25 + 5(-5) -15, then we do the multiplication next:
25 + (5 * -5 = -25) so:
25 + -25 - 10, the 25s cancel each other out and your left with:
0 - 10 which equals -10
5(7y + 2)
Distribute (multiply) the 2 to the numbers in the parentheses.
35y + 10
Answer:
the answer to the question is y=x+2.
When the 10 is to a negative power you move the decimal to the left. in this case its 5 spots. i believe your answer is .00005003
