Lydia graphed ALMN at the coordinates L (0,0), M (2, 2), and N (2,-1). She thinks ALMN is a right triangle. Is Lydia's assertion correct?
Yes, the slopes of LM and LN are opposite reciprocals.
No; the slopes of LM and LN are not opposite reciprocals.
Yes, the slopes of LM and LN are the same
No, the slopes of LM and LN are not the same.

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
