Answer:
Understand that a function is a rule that assigns to each input exactly one output. The graph of a function is the set of ordered pairs consisting of an input and the corresponding output.
Step-by-step explanation:
D=dollars earned
T=time spent painting the fence.
(1,5) (2,10) (3,15)
D=5T
37 times 720 divided by 20 is 36 then you need gas to run the 5 other miles.
Simple....
3x-10(x+2)=13-7x
Just solve for x.....
3x-10x-20=13-7x
-7x-20=13-7x
+7x +7x
-20=13
NO SOLUTION.
Thus, your answer.
Hey there!
A perpendicular line's slope to another line is always the negative reciprocal of slope.
If our line has a slope of two, we first must find the reciprocal, which is 1/2. Then, we put a negative on it.
Therefore, our equation is y=-1/2x+b.
I hope that this helps! Have a great day!
