Answer:
X=-2
Step-by-step explanation:
4x-4=-12
Add 4 on both sides
+4 +4
4x=-8
Divide by 4 on both sides
÷4 ÷4
X=-2
The domain is (-infinity, +infinity)
The range is (5, +infinity)
Answer:
67 degrees
Step-by-step explanation:
All angles in a triangle add up to 180 degrees. So...
23 + x + 90 = 180
113 + x = 180
x = 67 degrees
5n + 4 = 39
5n = 39 -4
5n = 35
n = 35:5
n = 7
