The opposite of -8 is 0 and the absolute value in 8
Step-by-step explanation:
Answer: 
<u>Step-by-step explanation:</u>
y = A cos (Bx - C) + D
- A (amplitude) = max - D
- B = Period/2π ---> Period is the distance from max to next max
- C = B · Phase Shift ---> Phase shift is distance from y-axis to max
- D (vertical shift) = (max + min)/2
D = (max + min)/2 = (3 - 11)/3 = -4
A = max - D = 3 - (-4) = 7
Period = 9π/4 - π/4 = 8π/4 = 2π
B = Period/2π = 2π/2π = 1
Phase Shift = π/4 - 0 = π/4
C = B · Phase Shift = 1 · π/4 = π/4
Equation:
y = 7 cos (1·x - π/4) + (-4)
Answer:
x = 3
Step-by-step explanation:
1. Plug 3 into g(x)
3 = -2x + 9
2. Subtract 9 on both sides
-6 = -2x
3. Divide by -2 on both sides to get x by itself
x = 3
I hope this helped :)
There’s a 30% difference between the percent of increase and percent of decrease. There is a 50% increase when it goes from 30 to 45. And a 20% decrease from 45 to 36.
