m∠A + m∠B = 90, since the angles are complementary.
The question also tells us that m∠A = (2x + 10) and m∠B = (-x + 55)
So, all we have to do is input the angle's values into the first equation:
(2x+10) + (-x+55) = 90
Simplify:
x + 65 = 90
x = 25
Input the variable into the angles:
m∠A = 2(25) + 10 = 50 + 10 = <u>60°</u>
m∠B = -25 + 55 = <u>30°</u>

Answer:
The answer is D ⇒ -4log(-x + 4)
Step-by-step explanation:
From the graph we chose the point of x-intercept (3 , 0)
∵ f(x) = -4log(-x + 4)
∴f(3) = -4log(-3 + 4) = -4log(1)
∵ log(1) = 0
∴f(3) = 0
If x = 0
∴ f(0) = -4log(0 + 4) = -4log4 = -2.40 ⇒ same value on the graph
∴ The answer is (D)
Answer:
It would be the first option: Last week, Rosemary walked at a faster pace.
Step-by-step explanation:
Last week, the speed was d=3h, as for this week, her speed was d=2.5h.
No one knows how many hours she walked this week so we cannot say that she walked a greater distance.
