Answer: 22, 38

               3, 7

               8, 12

<u>Step-by-step explanation:</u>

It is given that the PERIMETER is BETWEEN 22 and 38

-->          22 < P < 38

Perimeter = 2w + 2L

It is given that L = w + 5

Substitute P with 2w + 2L and substitute L with w + 5

                22 <  2w + 2(w + 5) < 38

                 22 < 2w + 2w + 10 < 38    

                  12 <          4w        < 28    

-->               3 <          w          < 7          

Since L = w + 5, then w = L - 5

Substitute P with 2w + 2L and substitute w with L - 5

                22 <  2(L - 5) + 2L < 38

                 22 < 2L + 2L - 10 < 38    

                 32 <          4L        < 48    

-->               8 <            L        < 12

Which table represents a linear function?
mart [117]
Well, a linear function is proportional, a straight line (on a graph). And the numbers must not have the same answer. For instance, if the X input is 5, and the Y output is 7. And then another X input is 5, and the Y output is 8, that's non-linear.

So, the Answer would be the third graph. This is because the X values are steadily increasing, and so are the Y values. 

For the X and Y values, for each time X increases by 1, Y increases by -8. This is, linear because both sides are constantly and evenly increasing.

Y = 6x - 4<br> y = -x + 3
likoan [24]

Answer:

  (1, 2)

Step-by-step explanation:

Subtract the second equation from the first:

  (y) -(y) = (6x -4) -(-x +3)

  0 = 7x -7 . . . . .  simplify

  0 = x - 1 . . . . . . divide by 7

  1 = x . . . . . . . . . add 1

  y = -1 +3 = 2 . . . substitute into the second equation

The solution is (x, y) = (1, 2).
