What is the answer to y=2x-9

Sorry to break it to you, but...

That's a line equation my dude. There's no answer.

x=4.5 y=0

Step-by-step explanation:

For the x coordinate set y to zero for the y coordinate set x to zero. Example:

0=2x-9

9=2x

4.5=x

answer: 4  

the square root of 16 is 4. it is a very simple mathematic concept. a square root when a number multiplied by itself will result in a number. here, the number 16 comes when 4 is multiplied by 4. hence the square root of 16 is 4. you can always figure out a square root by the inverse operation of squaring.  

all you should have to do is insert 1 where the c is, representing that one car is sold.

f(c) = 250c + 500

f(1) = 250(1) + 500

f(1) = 250 + 500

f(1) = 750

he earns $750 for each car sold.

hope this you! have a happy , here's a turkey!
