What is the slope of the line 2x – 5y = 12 ?

2x−5y=12

y = 2/5x + −12/5

Answer is x = 5/2y + 6 because....

First,  Add 5y to both sides.

2x − 5y + 5y = 12 + 5y

Then, Divide both sides by 2.

Therefor, your answer is going to be x = 5/2y + 6

2/5

Step-by-step explanation:

We are given the following equation of a line and we are to tell the slope of the line:

We know that the standard equation of a line is given by:

where m is the slope of the line.

So re-writing the given equation in the standard form:

Therefore, 2/5 is the slope of the line.

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

or

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:

  ⇒

then, the solutions are: or
