The midline is the y value that runs straight through the middle of the wave.If you can picture the standard sine function graph. f(x) = Sin(x) reaches a maximum y = 1 and minimum y = -1 so the midline is y =0.
This equation is shifted up 6 so the midline is shifted up 6
y = 6 is equation for midline
The answer to the question is B.
Answer:
Step-by-step explanation:
<u>The perimeters are equal:</u>
<u>Solve for x:</u>
- 12x - 24 = 4x
- 12x - 4x = 24
- 8x = 24
- x = 3
Answer:
x = 21 / 228
Step-by-step explanation:
4x - 10y = - 3 -----> equation 1
112x + 5y = 12 -----> equation 2
Multiply 2 on both sides in the equation 2,
2 ( 112x + 5y = 12 )
224x + 10y = 24 -----> equation 3
Add equations 1 & 3,
4x - 10y = - 3
224x + 10y = 24
_____________
228x + 0 = 21
228x = 21
x = 21 / 228
