Find a a pair of numbers of both 4y-4x=48 and y= x-11
stich3 [128]

Answer:

There is no solution because the slopes of the line are the same.

Step-by-step explanation:

4y - 4x = 48

    + 4x    + 4x        Add 4x to both sides

4y = 4x + 48          Divide both sides by 4

y = x + 12

Now set both equations equal to each other since they equal y

x + 12 = x - 11

-x         - x           Subtract x from both sides

12 ≠ -11                No Solution

What is X I need help i dont know how to do this
Anit [1.1K]

Answer:

x = 75

Step-by-step explanation:

Triangle BDH

The angle must add to 180 degrees

36+ 39 + DHB = 180

75 + DHB = 180

DBH = 180-75

DHB = 105

DBH + x = 180 since it is a straight line

105+ x = 180

x = 75
