Help PLEASEEE!!! Given that AC=30, AB=5x-21, BC=3y+4, CD=2x-3, and DA=4x+1, find the indicated variables for each question. Find the value of x, y, z.

x = 6

y = 7

z = 23

Step-by-step explanation:

ÀC = z + 7

30 = z + 7

30 - 7 = z

z = 23

2x - 3 = 5x - 21

21 - 3 = 5x -2x

18 = 3x

x = 18÷3

x = 6

4x + 1 = 3y + 4

4(6) + 1 = 3y + 4

25 = 3y + 4

3y = 25 - 4

y = 21 ÷ 3

y = 7

please mark as brainliest i appreciate so much

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
