Answer:
Step-by-step explanation:
since we can see that the lines are parallel
and we can see that the both are interior angles and when we sum up both angles we get 180
2x - 5 + 45 = 180
2x + 40 =180
2x = 180 - 40
2x =140
x = 140/2
x = 70
Answer:
It would be constant.
Step-by-step explanation:
Since there is no x value, the line will have no slope and just be horizontal about y= -2.
Answer:

in a graph the x value at the y intercept is 0
is a typical decay function
if x = 0 thus
= 1
so at 0 the function value would be A

Step-by-step explanation:
DrH = DrT + 0.019
DrE = DrH - 0.020
DrH is the most and DrE is the least
