Angles B and D are congruent so:
(360-112-74)/2=87°
Answer:
D. y = 12.5x + 15
Step-by-step explanation:
Using the values provided in the table, the only equation that would be valid would be the following...
y = 12.5x + 15
That is because if we substitute any value provided in the table for x , this equation will correctly output the y value shown in the table for the attached x-value. For example, in the table 5 nights (x = 5) should have a total cost of 77.5 (y = 77.5)... Therefore, if we substitute 5 for x in the function it should give us 77.5 which it does.
y = 12.5(5) + 15
y = 62.5 + 15
y = 77.5
I could explain it, but you have to ask me, other than that the answer is 5(x+7)(9x-4).
Answer:
x= 11, -15
Step-by-step explanation:
(4x + 5) + x^2 +1 0) = 180
x^2 + 4x + 15 = 180
x^2 + 4x + 15 - 180 = 0
x^2 + 4x - 165 = 0
x = 11, -15
