Answer:
2.195
Step-by-step explanation:
Use a calculator
P = -23 + 0.13y
For y = 350:
p = -23 + 0.13(350) = -23 + 45.5 = 22.5
For y = 400:
p = -23 + 0.13(400) = -23 + 52 = 29
For y = 450:
p = -23 + 0.13(450) = -23 + 58.5 = 35.5
If I am reading the question correctly it would come out to -6x+42 First do all the addition and squaring, then factor in that negative. You come out to -2x^3 +2x^3-4x-2x+25+5+9+3. The x^3's cancel, the -x's add to -6x, then all that other adds to 42.
9.74 because if you do 604 divided by 62 you will get 9.74 and if you do 9.74 and multiply it by 62 you will get 604<span />
