The answer would be 1,053
2x-5y =-5
14x+5y=-5
---------------
16x = -10
x = -10/16
x = -.626
2x-5y = -5
2(-.625) -5y = -5
-1.25 - 5y = -5
-5y = -3.75
y = .75
Choice A is approximately -.6 and .8 the others are not going to be close
3750(0.20)=$750
1/5 as a percent is 20% and as a fraction it is 0.20
the upside down T is always perpendicular so the answer is b. :)
Using Substitute method:
Replace y value of equation 2 into equation 1:
4x + (x+6) = 1
Solve for x:
4x + x + 6 = 1
5x = 1 - 6
5x = -5
x = -5/5
x = -1
Pick any of the two equation, replace x with it's value -1 and solve for y:
y = (-1) + 6
y = -1 + 6
y = 5
Solution: (-1, 5)
