Answer:
6x = 9
Step-by-step explanation:
4x-5y = 12
2x+5y = -3
Add the equations together
4x-5y = 12
2x+5y = -3
-------------------
6x + 0y = 9
6x = 9
1

Add 2 to both sides:

Divide both sides by -4 (this is negative, so we have to swap the inequality sign):

2

Expand the left hand side:

Add 8 and y to both sides:

Divide both sides by 3

3-4
Nothing different from 1 and 2, apply the same logic (expand sides, gather constant and non-constant terms together, solve for the variable) and you will solve them
D: {0, 1, 2, 3}
R: {−3, −2, 2, 5}
The relation is a function.
That's the answer.
Answer:
longer parallel sides are 150ft each with 4 shorter sides at 25ft each making a rectangle and 3 identical sections.
Step-by-step explanation:
150 + 150 = 300
4 ×25 = 100
300+100=400
