Answer:
x=40°
Step-by-step explanation:
(x-5)+(x+15)=90°
2x+10=90
2x=80
x=40°
Answer:
5x + 30
Step-by-step explanation:
5(5+x)
=(5)(6) + (5)(x)
=30 + 5x or 5x + 30
Answer:
domain = {x|xER}
range = {y|y≥0,yER}
Step-by-step explanation:
|x| means the absolute value which in this case is the distance from 0. On a graph this function would look like a v and would mean it would have infinite x-values since it is opening upwards in both directions.
For the range the vertex of this function is (0,0), if the x-coordinate were 0 the y-coordinate would be 0 because the absolute distance from 0 is 0. for another x-coordinate say -2 the absolute distance from 0 is 2 meaning the y-value is 0 since y=|x|, making the coordinate (-2,2) meaning the range is every y value must be above 0 since there is no way for the y-value to be negative
