Answer:

Step-by-step explanation:

It is a bit ambiguous. I'm assuming that what they want you to do is to substitute

y = 140

x = 4  

Into the two equations that went into making the answer of 4 come up

y = 30x + 20

y = 30*4 + 20

y = 120 + 20

y = 140 which is in agreement with your answer

==========

y = 15x + 80

y = 15*4 + 80

y = 60 + 80

y = 140

==============

Conclusion

both equations give the same answer. Both equations are correct.

Answer:

So both equations are true

Step-by-step explanation:

#4 was asking you to substitute x = 4 into both equations to see if it's the solution of the equations.

Substitute x = 4

Ritz equation

y = 30x  + 20

y = 30(4) + 20

y = 120 + 20

y = 140

Smits equation:

y = 15x + 80

y = 15(4) + 80

y = 60 + 80

y = 140

Both companies charged same price  $140 for 4 days

So both equations are true

Does this table represent a function? why or why not? x: 2 3 3 4 5 y: 1 4 3 2 5
gayaneshka [121]
Let's put the chart into ordered pairs:
(x, y)
(2,1)
(3,4)
(3,3)
(4,2)
(5,5)

In bold, we see that there are two y-values at x=3. This means that this relation fails the vertical line test (two points on the same verticle line). This is not a function. 

The answer options may be mis-written. 
The answer is no, because one x value corresponds to more than one y-value.
