1. 7x-4y= -8 and x+2y= 14 solution as (x,y) pls help!!

Answer:

(2 2/9, 12 5/9)

Step-by-step explanation:

multiply both sides of x+2y=14 by 2: 2x+4y=28

Add 7x-4y=-8 and 2x+4y=28: 9x=20

x=20/9

Plug in 20/9 into x+2y=14: 20/9+2y=14

2y=11 7/9

y= 11 14/9

y= 12 5/9

Answer:

29,-14

Can someone help me with these questions. (Answer 1 or answer them all I don't care.)

The Hydro water department has a monthly service charge of $13.90 and a volume charge of $1.45 for every 100 cubic feet of water.

The total monthly cost is equal to the service charge plus the charge for the volume used during the month. If we let x represent the number of cubic feet of water (in hundreds) and y represent the total monthly cost, then we have:
total monthly cost = volume charge + service charge
y = 1.45x + 13.90

If the Johnson family used 200 ft3 more water this month than last month, then they can expect
A. an increase in their water bill of $2.90.

B. an increase in their water bill of $27.80.

C. a decrease in their water bill of $2.90.

D. a decrease in their water bill of $27.80.
