The graph below shows a system of equations: Draw a line labeled y equals minus x plus 5 by joining the ordered pairs 0, 5 and 5

Montano1993 [528]

Answer:

The x-coordinate of the solution is x=3

Step-by-step explanation:

we have

$y=-x+5$ ------> equation A

$y=x-1$ ------> equation B

Solve the system of equations by substitution

Substitute equation B in equation A and solve for x

$x-1=-x+5$

$x+x=5+1$

$2x=6$

$x=3$

Find the value of y

$y=x-1$ ------> $y=3-1=2$

The solution of the system of equations is the point (3,2)

therefore

The x-coordinate of the solution is x=3

The Changs received a delivery of fuel oil totaling 35.00 gallons. The oil cost $3.05 per gallon. What did the Changs pay for th

Ede4ka [16]

Answer:

$106.75

Step-by-step explanation:

Since the cost of a gallon of oil cost $3.05, we are going to have the equation y = 3.05x, where x represents the number of gallons of oil.

Since the Changs have 35 gallons of oil, the equation would be;

3.05(35) = 106.75

The Changs paid $106.75 for the delivery.
