Answer:
Can you put a picture of the table? I don’t know how to do the math if you don’t show the table
Step-by-step explanation:
Take into account that in general, a linear function can be written as follow:
where m is the slope of the line and b the y-coordinate of the y-intercept.
In this case, you have that m=1/5 and b=-3, then, the line equation is:
In order to graph the line, proceed as follow:
Use two values of x to replace into the equation for y, for instance, use 0 and 5:
The previous results mean that (0,-3) and (5,-2) are two points on the line.
Place the previous points on the coordinate system, and draw a straight line which crosses these points:
The red line is the graph of the given function.
Answer: State that y = 430-x, and substitute it into the second equation 6x +4.5(430-x)= 2175.
Solve for x. Then plug in what you get for x into the x+y=430 equation and solve for y. Your number of adult tickets should equal 160, and your number of child tickets should equal 270.
Step-by-step explanation:
Subtract 4 from 9 because parentheses first.

Considering the period of the cosine function, it is found that it takes 40 seconds for the wheel to complete one turn.
<h3>What is the period of the cosine function?</h3>
The cosine function is defined by:
f(x) = acos(bx + c) + d.
For the period, we have to look at coefficient b, and the period is:
P = 2π/|B|
For this problem, the function is given by:
h(x) = 15 cos(π/20)
Hence B = π/20, and the period is:
P = 2π/|B| = 2π/(π/20) = 2 x 20 = 40 seconds.
Hence it takes 40 seconds for the wheel to complete one turn.
