The number of pets per household for Mrs. Anderson's Class and Mrs. Murphy's Class are shown in the dot plots. Which of these three statements appear to be true?
A) I only
B) I and III
C) II and III
D) III only

I think B) I and III

A. Only I.

Step-by-step explanation:

Mrs. Murphy's class has more pets that Mrs. Anderson's class.

This is shown on the graph, is you count up the dots closely, then, you will see that Mrs. Murphy's class has more pets than Mrs. Anderson's class.

hope this helps.

I am terribly sorry if I am wrong.

(0,-3) see attached graph

step-by-step explanation:

a. to solve the system, graph the two equations.

x = y+3 becomes y=x-3 has m=1/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move up 1 unit and 1 unit to the right. plot a point and connect.

y=-4x+3 has m =-4/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move down four units and to the right 1 unit. plot a point and connect.

the solution is the point (x,y) where the two lines intersect. by the graph below it is (0,-3).

b. to solve by substitution, substitute y = -4x-3 into x= y+3

x= (-4x-3) +3

x=-4x

5x=0

x=0

now substitute x = 0 back in to find y.

y= -4(0)-3

y=0-3

y=-3

solution is (0,-3)

c. use elimination by adding the equations together.

x-y=3

4x+y=-3

5x=0

x=0

then substitute into one equation to find y.

y=-4(0)-3

y=-3

mean, 40.6
