Which graph represents the following system of inequalities?<br> y &gt; 2x - 5<br> y &lt;-3x
NARA [144]

Answer:

The graph i the attached figure

Step-by-step explanation:

we have

y > 2x-5 ----> inequality A

The solution of the inequality A is the shaded area above the dotted line y=2x-5

The slope of the dotted line is positive

The x- intercept of the dotted line is the point (2.5,0)

The y- intercept of the dotted line is the point (0,-5)

y < -3x -----> inequality B

The solution of the inequality B is the shaded area below the dotted line y=-3x

The slope of the dotted line is negative

The x- intercept of the dotted line is the point (0,0)

The y- intercept of the dotted line is the point (0,0)

The solution of the system of inequalities is the shaded area between the two dotted lines

see the attached figure

Go to a clothing store with
olga2289 [7]

Answer:

original price $75

discount $18.75

sale price $56.25

Step-by-step explanation:

I found a pair of dress pants for $75.

Since the discount is 25%, then the discount is

25% of $75 = 0.25 × $75 = $18.75

The sale price is the original price, $75, minus the discount, $18.75.

$75 - $18.75 = $56.25
