I'm not totally sure, but it might be y= x/7.
Answer:
Angle UST= 180
Step-by-step explanation:
Im not so sure but angle U= 25 degrees+ angle S=95 degrees+ angle T=60 degrees. Dont rely on me too much I'm only a middle school kid that got put in a highschool course for some apparent reason.
Answer:
Part A) The graph in the attached figure
Part B) 
Step-by-step explanation:
Let
y------> the price of gas
x-----> the volume of gas purchase
we know that
The relationship between the cost of gas and the volume purchase represent a direct variation and remember that a relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form 
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
In this problem the constant of proportionality k is equal to

and the y-intercept b is equal to zero because the line passes through the origin

therefore
the linear equation is


using a graphing tool
see the attached figure
Answer:
No
Step-by-step explanation:
I think C is the correct answer because the slope is not proportional however they are all around 2000. So multiply 2000 by 42 and you get 84,000. Which is about 81,000.
