Answer:
1. (1,10) 2. (2,-3) 3. (3,3)
Here to solve the equation we need to plug in the value y as given. -5x+2(7x)=9. -5x+14x=9. 9x=9. X=1.
Answer: Your answer is 0 (F.O.I.L) first. outer. inner. last. Or you could use what my teacher calls the magic box
Step-by-step explanation:
So for the boxes you multiply for example the top left box you multiply the 9 above it and the 9 to the left or like the top right box you multiply the -9 above it and the 9 on the outside of the box to the left
the answer is (f/g)(x) = 2(x^2 - 7) + 1
= 2x^2 - 14 + 1
= 2x^2 - 13
Answer: A.4Runner cost more for $11.02
B.Cost of fuel for Elentra: 3.75*3.59=$13.46
Cost of fuel for 4Runner : 6.818*3.59=$24.48
Step-by-step explanation:
A.Find how many gallons 4Runner spends on 150 mile trip.
use proportion
22:1=150:x
22x=150
x=150/22
x=6.818 gallons
Cost of fuel for 4Runner : 6.818*3.59=$24.48
Calculation for Elentra:
40:1=150:x
40x=150
x=150/40
x=3.75 gallons
Cost of fuel for Elentra: 3.75*3.59=$13.46
Cost of fule for 4Runner-Cost of fuel for Elentra=24.48-13.46=$11.02
4Runner cost more for $11.02
B.Cost of fuel for Elentra: 3.75*3.59=$13.46
Cost of fuel for 4Runner : 6.818*3.59=$24.48
