A) $5: How much per DVD

     x:# of DVDs he gets

        +25:Shipping fee

     ≤: He has a max of 125 he can spend an equivalence of or less but no more.  125 can be on the left end of a greater than or equal to the equation as well.

B)5x+25 ≤125

Answers

3t<-15 solve for t

divide both sides by 3
3t/3 < -15/3

Simplify
t < -5

Anser is 
a. t<-5
If 3t < -15 all you need to do is divide by 3 on both sides, 

t < -5

always makes you always go from the x to the y axis!! sorry if this didn’t help much

Answer:

Follow the lines

Step-by-step explanation:

Follow what the lines go with what the table has.

To make this really easy, find the slope of the line

To do this you find an easy point.

Ex. x=3 and y= 150

then take it into a slope y-intersept formula

y= mx

150= 3x

50 = x

so for every time x goes up one interval, y increases at a rate of 50.

And for y, do the opposite, for every 50 y, x goes up 1.

By following this linear path, you should really beable to solve the graph on the right. (If you need to, use a calculator for dividing the y numbers by 50 to get x)

y= 50x is ur slope/formula

(Ill leave the rest for you to answer with this data above ;) )
