Step-by-step explanation:
<A + < B = 90° { being complementary angles)
2x + 10° + 3x + 15° = 90°
5x = 90° - 15° - 10°
5x = 65°
x = 13°
Now
<B = 3x + 15° = 3 *13° + 15° = 54°
Hope it will help :)
Answer:
the constant in this expression is 9 because it is not a coefficient of any variable
I think the answer is r = 5/12
So a function in math is where a relationship or expression involving one or more variables.
So, It would be yes it's a function, -2=1 yes it is 1=2 yes it is, 3=3 yes it is, and 4 1/2 is a 4 and a five (: Hoped this helps you!
Good luck!
Just distribute -5
30u+15x-20
Don’t forget to change negative signs to positive signs if their multiplied by negatives
