What is the solution of the system of equations y=5.69x+25 y=9.49x+6

Given :

A system of equations y = 5.69x + 25 and y = 9.49x + 6.

To Find :

The solution of the system of equation.

Solution :

Subtracting equation 2 by 1, we get :

y - y = ( 9.49x + 6 ) - ( 5.69x + 25 )

0 = 3.8x - 19

x = 5

Putting value of x in equation 1, we get :

y = (5.69×5) + 25

y = 53.45

Therefore, the solution of the system of equations is ( 5, 53.45 ).

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
