Stores X, Y, and Z each sell a certain item that has a given list price. Stores X and Y are located in a state with a 5 percent

hram777 [196]

Answer:

B. x=y

Step-by-step explanation:

A 5% tax charge is equivalent to multiply the current price by 1.05. On the other hand, a 5% discount is equivalent to substrace the current the 5% of it, so in the end, you multiply the current price by 0.95.

For X we should multiply first by 0.95, then by 1.05

For Y we multiply first by 1.05, then by 0.95

Hence, if L = price list, we have

x = L*0.95*1.05 = 0.9975L
y = L*1.05*0.95 = 0.9975L
z = L

As a result, x=y<z. Option B is correct.

Note that applying discount first or charging taxes first doesnt matter because the order of the factors doesnt ater the product.

Please actually answer and not just take my points and answer quick this is timed

Arte-miy333 [17]

Answer:

Part A) The graph in the attached figure (see the explanation)

Part B) The ordered pair is not included in the solution area for the system (see the explanation)

Step-by-step explanation:

Part A) we have

$y$ ----> inequality A

The solution of the inequality A is the shaded area below the dashed line $y=4x-8$

The slope of the dashed line is positive

The y-intercept of the dashed line is (0,-8)

The x-intercept of the dashed line is (2,0)

$y\geq -\frac{5}{2}x+5$ ----> inequality B

The solution of the inequality B is the shaded area above the solid line $y=-\frac{5}{2}x+5$

The slope of the solid line is negative

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

The x-intercept of the solid line is (2,0)

The solution of the system of inequalities is the shaded area between the dashed line and the solid line

see the attached figure

Part B) is the point (5, -8) Included in the solution area for the system?

we know that

If a ordered pair is a solution of the system of inequalities, then the ordered pair must satisfy both inequalities

Substitute the value of x=5, y=-8 in each inequality and then analyze the results

<em>Inequality A</em>

$-8$

$-8$ ----> is true

so

the ordered pair satisfy inequality A

<em>Inequality B</em>

$-8\geq -\frac{5}{2}(5)+5$

$-8\geq -7.5$ ---> is not true

so

the ordered pair not satisfy the inequality B

therefore

The ordered pair is not included in the solution area for the system
