Answer:
r = 7
Step-by-step explanation:
To solve this, we can plug in a pair of x and y values and solve for r.
y = rx | Plug in a pair
42 = r*6 | Now divide both sides by 6
7 = r.
We can test this by plugging in r with a pair.
y = (7)x
77 = 7*11, 77 = 77, This equation is correct.
Answer:
0
Negative
Un-defined
Things you need to know:
Any line parallel to the x axis is 0
any line parallel to the y axis is infinite/un-defined
Any line that is slanted in that way shown in the picture is negative vice versa the other way it is slanted will be positive.
The driver's tip was $1.45 because the trip cost $8.55 (2.25+1.5+1.5+1.5+1.5+ 0.3) and Eric gave the driver $10 so to find how much the driver got tipped, you need to subtract 8.55 from 10 so $10 - $ 8.55 = $1.45
A. because when you face an equality, you need to have a negative and positive answer.
