Answer:
c) 72
Step-by-step explanation:
- the function f(x)=7x+2 represents the number of cars that drive by in x minutes
- x = 10
- f(10) = 7×10+2 = 70+2 = 72
This process is very simple. All you are doing is creating a table of values somewhere to help you graph this function. As you can see, the coordinates of
and
are all touched on this graph, letting you know that this information is accurate.

Answer:
Option C
The student's conclusion is correct because the solution to the system of equations
and
is 
Step-by-step explanation:
Let
x------> the cost of each burger
y-----> the cost of each sandwich
we know that
-----> equation A
----> equation B
Solve the system of equations
Multiply the equation B by 
----->
------> equation C
Adds equation A and equation C

Substitute the value of x in the equation B



The solution of the system of equations is the point 
so
The price of each burger is 
The price of each sandwich is 
Disagree. Even though it has no b it is still a line but a horizontal line. It will be at 7 on the y- intercept but horizontal.
