Answer:

y = 2 - 5/4x

or

y = 2 - 1.25x

Step-by-step explanation:

Slope-intercept form is y=mx+b, where m=slope and b=y-intercept. Let's make this equation look more like that by isolating y on one side.

5x + 4y = 8

Subtract 5x from both sides.

4y = 8 - 5x

Divide both sides by 4.

y = 8/4 - 5/4x

y = 2 - 5/4x

Y=-5x/4+2 so the slope is -5x/4 and the y intercept is 2.

Answer:

a) $86.11

b) $467.33

Step-by-step explanation:

no. of gallons saved 'n' per year

n = (10000/33) - (10000/36)

n = 2500/99

Amount saved = 3.41×n = 3.41×2500/99

= $86.11

b) over 5 years:

86.11( 1 + (1.041) + (1.041)² + (1.041)³ + (1.041)⁴ )

= 86.11(5.427157431)

= $467.33

<u>Given</u>:

The given equations are -6 x+4 y=22 and y=11-4 x

We need to determine the pair of numbers that is a member to the system of equations.

<u>Pair of numbers:</u>

The pair of numbers can be determined by solving the system of equations.

Let us use the substitution method to solve the equations.

Substituting y=11-4 x in the equation -6 x+4 y=22, we have;

-6 x+4 (11-4x)=22

  -6 x+44-16x=22

             44-22x=22

                  -22x=-22

                        x=1

Thus, the value of x is 1.

Substituting x = 1 in the equation y=11-4 x, we get;

y=11-4(1)

y=11-4

y=7

Thus, the value of y is 7.

Hence, the pair of numbers that is a member of both the equations are (1,7)
