Answer:
No
Step-by-step explanation:
No, it's not a function as it fails the vertical line test
Solve the equation and it will add up to -6 so
3×-7=-21
-21-10=-31
-31+25=-6
Answer:
x = 30
Step-by-step explanation:
The interior angles of a triangle must always add up to 180.
2x + 2x + 3x - 30 = 180
Add 30 to both sides to seperate variables.
2x + 2x + 3x = 210
Combine like terms.
7x = 210
Divide by 7 to isolate x.
x = 30
