Asystem of equations has 1 solution. if 4x - y = 5 is one of the equations, which could be the other equation?
y=-4x+5
y = 4x-5
2y = 8x - 10
-2y = -8x - 10

Answer

y=-4x+5

Step-by-step explanation:

The given equation is

In slope intercept form,

We want a second equation that will form a system with unique solution with the given equation.

To achieve this the second equation must not have a slope of 4.

The first equation, y=-4x+5 has a slope of -4 which is not equal to 4.

Hence the correct answer is y=-4x+5

We can see that the remaining options have a slope of 4 when simplified.

Second option: y = 4x-5

Third option:2y = 8x - 10----->y=4x-5

Fourth option: -2y = -8x - 10----->y=4x+10

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
