Answer:
8 hours
Step-by-step explanation:
6x+20=68
subtract 20 from both sides
6x=48
divide 6 both sides
x=8

What is a sinusoidal wave?
Alternatively called a sine wave is a type of wave that shows a repetitive pattern or oscillation, it normally starts from a low point moves to the next point which is usually higher than the previous and repeats itself as the whole process continues
You would graph the two lines. Then use Y=mX+b
10=5/4(4)+b 5/4 is the slope or distance between the two lines.
solve for b
10=5+b
-5
5=b
Y=5/4X+5 would be your answer

Answer:
Step-by-step explanation:
The model equation: y = mx + b
First, we should find the slope. The equation is

The numbers in the equation stand for the y or x variable from either the first or second point. So, we plug in the numbers and get,

=
= 
What we have right now is y = 1/2x + b. To solve for b (the y-intercept), we have to take one of the points and plug in the x and y variables. If we take the first point, the equation becomes,
3 = 1/2(4) + b
3 = 2 + b
b = 3 - 2
b = 1
The final equation is,
y =
x + 1
