The product is: 3/2-5/4 = (6-5)/4 = 1/4
Answer:
(-60/11,111/11)
Step-by-step explanation:
Solving simultaneously, 4x - 3y=6
-3(6x + y=42)
then it becomes, 4x - 3y=6
-18x - 3y= 126 subtracting the two equations,
22x= -120, x= -60/11 and y = 111/11
Answer:
Step-by-step explanation:
8x+9/x^2-13x+42
Write 8
x as a fraction with denominator 1
8x+9/x^2-13x+42
then we multipuly 8x/1 by x^2/x^2
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
