Define a function. Describe what the vertical line test is used for. Describe a real life situation that can be represented by a
Marrrta [24]
A function is a relationship with a quantity (number). For example, if you made a table, and had one side be 1 2 3 4 5 (X axis) and then the y axis (other side) be 5, 10, 15, 20, 25, the function (rule) would be y= x5. The vertical line test is used to see if a graph has a function or not, so if it creates a vertical line on a graph, it has a function.
A real life situation would be miles per hour, so, for the x axis (hours) it said 1, and for the y axis (miles) it would be 60, this means in a duration of 1 hour you went 60 miles. Well, lets say you went 2 hours driving, the miles would be 120. 
For 3 hours, it would be 180. The function here is y= x60!

9-x/5=3. Solve for x
kari74 [83]

Answer:

\boxed{\boxed{\sf x=-6}}

Step-by-step explanation:

\sf \cfrac{9-x}{5}=3

\sf \cfrac{5\left(9-x\right)}{5}=3\times \:5

\sf 9-x=15

\sf 9-x-9=15-9

\sf -x=6

\sf \cfrac{-x}{-1}=\cfrac{6}{-1}

\sf x=-6
