Answer:

Step-by-step explanation:
Given
The attached graph
Required
Determine the line equation
First, list out two points from the graph


Next, calculate the slope (m)




The equation in slope intercept form is:

This gives:


Open bracket

Answer:
7 dogs
Step-by-step explanation:
$30/3 = how many dollars per dog
$10 per dog he washes
$70/$10 = 7, he washes 7 dogs
21+45+70=136
136+(2+x)=180
First subtract 136 from both sides
(2+x)=44=M<ROS
Subtract 2 from both sides
x=42
Answer:
Yes and no, there are many different ways to put it ;)
Answer:
Choice A.
Step-by-step explanation:
Apply the vertical line test.
If a vertical line intersects 2 or more points on the graph, the relation is not a function.
If all vertical lines intersect at most 1 point on the graph, the relation is a function.
Any vertical line in Choice A. intersects 1 single point. Choice A. is a function.
There are vertical lines that would intersect 2 points of the graph in Choices B., C., and D., so they are not functions.
