The first thing we must do for this case is to find the relationship between the variables.

We have then:

AB = DC\\4y - 2 = 2y + 6

From here, we clear the value of "Y":

4y - 2y = 6 + 2\\2y = 8

y = \frac{8}{2}\\y = 4

On the other hand we have:

AD = BC\\3x - 1 = 2x + 2

From here, we clear the value of "x":

3x - 2x = 2 + 1\\x = 3

Then, replacing values we have:

AB = DC = 4y - 2 = 4 (4) - 2 = 16 - 2 = 14\\AB = DC = 14

On the other hand:

AD = BC = 2x + 2 = 2 (3) + 2 = 6 + 2 = 8\\AD = BC = 8

Finally, the perimeter is given by:

P = AB + DC + AD + BC

Substituting values we have:

P = 14 + 14 + 8 + 8\\P = 44

Answer:

the perimeter of ABCD is:

44 units

Which of the following sets of values correctly completes the T chart for the equation Y =|3x+1|. -5,1,7
Ivahew [28]

Option C:

5, 1, 7

Solution:

Given equation:

y = |3x + 1|

In the chart, x values are given as –2, 0, 2.

To find the value of y for the corresponding x given.

Substitute x  = –2 in the equation of y.

y = |3(–2) + 1|

  = |–6 + 1|

  = |–5|   (Absolute value of a negative number is positive)

y = 5

Substitute x  = 0 in the equation of y.

y = |3(0) + 1|

  = |0 + 1|

  = |1|

y = 1

Substitute x  = 2 in the equation of y.

y = |3(2) + 1|

  = |6 + 1|

  = |7|   (Absolute value of a negative number is positive)

y = 7

Option C is the correct answer.

The values of y are 5, 1, 7.

The answer image of the table is attached below.
