Answer:
x ≤ 10,625
Step-by-step explanation:
$8500 must be less than or equal to 80% of the blue book value
We can write the following inequality:-
0.80x ≤ 8500
x ≤ 10,625 where x is the blue book value

Answer:
B
Step-by-step explanation:
Interior angles of a triangle = 180°
3x°+3x+10°+4x-30°=180°
10x°-20°=180°
10x°=180°+20°
10x°= 200°
10x°/10=200°/10
x°=20°

Answer:
A = 7 and C = 2
Step-by-step explanation:
the constant C represents the average value of the wave. To find its value, we need to calculate the average between the y-coordinates of the highest and the lowest point.
The highest point has y = 9, and the lowest point has y = -5, so we have:
C = (9 - 5)/2 = 4/2 = 2
The value of A represents the increase in the amplitude of the wave.
For A = 1, the amplitude is 2 (lowest point = average - 1, highest point = average + 1)
So, in this case, the amplitude is the difference in the y-coordinates of the highest and the lowest point, and A is equal half the amplitude:
A = (9 - (-5)) / 2 = (9 + 5)/2 = 14/2 = 7
