Solve the following system of equations. enter the y-coordinate of the solution. round your answer to the nearest tenth
5x+2y=7
-2x+6y=9

1.7

Step-by-step explanation:

( 5x + 2y = 7 ) 2

( - 2x + 6y = 9 ) 5

10x + 4y = 14

-10x + 30y = 45

34y = 59

y = 1.7

c. 6tan80

step-by-step explanation:

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
