Domain = set of input value
Range = set of output values
<h3>#1</h3>
- Domain: -2 < x ≤ 2 or (-2, 2]
- Range: -4 < y ≤ 4 or (-4, 4]
<h3>#2</h3>
- Domain: -5 ≤ x ≤ 1 or [-5, 1]
- Range: -1 ≤ y ≤ 5 or [-1, 5]
<h3>#3</h3>
- Domain: -4 < x < 4 or (-4, 4)
- Range: -1 ≤ y < 3 or [-1, 3)
Answer:
x = 3
y= 12
Step-by-step explanation:
2x + 2y = 30
y - 4x = 0 /*2
2x + 2y = 30
2y - 8x = 0
-----------------
10x = 30
x = 3
y= 12
