Answer:
150% change
Step-by-step explanation:
Formula for Percent change = C =[ (new - old)/ old ]* 100%
C = [ (25 in. - 10 in.) / 10 in. ] = [15/10 ] * 100% = 150 %
The mistake is in step 3:
I: −2m =−12 − 2n
II: 2m = 8 + 8n
the student set both right sides of the equations equal (−12 − 2n = 8 + 8n), but the left sides aren't equal: first equation has -2m, second has +2m so the signs of one of the equations must be inverted first
Answer:
I think the answer is 2. Hope this helps!
Answer:
Step-by-step explanation:
Because you can't do -x+1 so it would be (1,0) and then you have x^2 +3x-4 which is (-5,6)
