The Jackson High School gymnastics team sells calendars for their annual fundraiser. The function rule below describes the amoun

t of money the team can raise, where y is the total amount in dollars, and x is the number of calendars sold.
y=3x+28

Use the function rule to find the corresponding range values when the indicated number of calendars is sold. Show your work for finding each range value.

a. 50 calendars
b. 75 calendars
c. 90 calendars
d. Create a table of values that includes the x- and y-values for parts a-c. Write a sentence to explain what the range represents for this function.

Answer:

Part A:

Since the slopes of the lines are not equal, the pair of equations for lines A and B will have one solution.

Part B:

(3 ,5 ) is the solution to the equations of lines A and B.

Step-by-step explanation:

Part A:

We are required to determine the number of solutions that the pair of equations for lines A and B have. To do this, we shall determine the slope of each line;

A straight line labeled A joins the ordered pair 2, 6 with the ordered pair 6, 2. The slope is defined as;

(change in y) / (change in x)

The slope of line A is thus;

(2 - 6)/(6 - 2) = -1

A straight line B joins the ordered pair 0, 3 with the ordered pair 4.5, 6.

On the other hand, the slope of line B is;

(6 - 3) / (4.5 - 0) = 2/3

Since the slopes of the lines are not equal, the pair of equations for lines A and B will have one solution.

Part B:

What is the solution to the equations of lines A and B?

We first need to determine the equation of each line;

Line A, the slope was found to be -1 and the line passes through (2,6)

The equation of the line in slope intercept form is;

y = -x + c

6 = -2 + c

c = 8

y = -x + 8

On the other hand, the slope of line B was found to be 2/3 and the line passes through (0,3). Therefore, we have;

y = 2/3x + c

3 = 2/3 (0) + c

c= 3

y = (2/3)x + 3

The graph of these two lines is shown in the attachment below. The lines intersect at (3 ,5 ) which is the solution to the equations of lines A and B.

The graphical solution to a system of linear equations is given by the point of intersection of the two lines representing each equation.

Assume that a spherical cell, with a diameter of 18 μm, has spherical mitochondria, each with a diameter of 0.18 μm. If mitochon
laiz [17]

Since the linear dimension of the mitochondria is 10^-2 times that of the cell, the volume as a proportion of cell volume will be (10^-2)^3 = 10^-6. In order to make up 0.134 of the cell volume, there must be

(1.34×10^-1)/(10^-6) = 1.34×10^5

mitochondria in the cell.

There are about 134,000 mitochondria.
