Answers

Answer:

$y\geq x-2$

$x+2y<4$

Step-by-step explanation:

step 1

Find the equation of the first inequality

Find the equation of the first solid line

we have the ordered pairs

(0,-2) and (2,0)

Find the slope

The formula to calculate the slope between two points is equal to

$m=(y2-y1)/(x2-x1)$

substitute the values

$m=(0+2)/(2-0)$

$m=(2)/(2)$

$m=1$

The equation in slope intercept form is equal to

$y=mx+b$

we have

$m=1$

$b=-2$ ---> the y-intercept is given

substitute

$y=x-2$

Remember that

Everything to the left of the solid line is shaded

The inequality is

$y\geq x-2$

step 2

Find the equation of the second inequality

Find the equation of the second dashed line

we have the ordered pairs

(0,2) and (4,0)

Find the slope

The formula to calculate the slope between two points is equal to

$m=(y2-y1)/(x2-x1)$

substitute the values

$m=(0-2)/(4-0)$

$m=(-2)/(4)$

$m=-(1)/(2)$

The equation in slope intercept form is equal to

$y=mx+b$

we have

$m=-(1)/(2)$

$b=2$ ---> the y-intercept is given

substitute

$y=-(1)/(2)x+2$

Remember that

Everything below and to the left of the line is shaded

The inequality is

$y<-(1)/(2)x+2$

Rewrite

Multiply by 2 both sides

$2y<-x+4$

$x+2y<4$

therefore

The system of inequalities is

$y\geq x-2$

$x+2y<4$

Step-by-step explanation:

The owner of a sporting goods store has decided upon a 50-percent markup on all apparel. How much will the store charge for bicycle shorts it purchased from the wholesaler for $10 each? What did the store pay for running shoes that are selling for $75?

Answers

Based on the amount of markup, the store:

Will charge $15 for the bicycle shorts
Paid $50 for the running shoes

If the store bought the shorts for $10 and marks it up by 50%, the amount it will sell it is:

= Cost of shorts x ( 1 + markup)

= 10 x ( 1 + 50%)

= 10 x 1.5

= $15

If the store purchased shoes for $75, the cost would have been:

75 = Cost x ( 1 + 50%)

Cost = 75 / 1.5

Cost = $50

In conclusion, the store will sell the shorts for $15 and bought the shoes for $50.

Answer:

$15, $50

Step-by-step explanation:

Given:

The owner of a sporting goods store has decided upon a 50-percent markup on all apparel.

Question asked:

How much will the store charge for bicycle shorts it purchased from the wholesaler for $10 each?

What did the store pay for running shoes that are selling for $75?

Solution:

Cost price of bicycle shorts = $10

Mark up amount = 50% of $10

= $(50)/(100) *10=(500)/(100) =5$

Selling price of bicycle shorts = Cost price + Mark up amount

= $10 + $5 = $15

Thus, the store will charge $15 for bicycle shorts.

Selling price of running shoes = $75

Cost price of running shoes = ?

Let Cost price of running shoes = $x$

Mark up amount = 50% of Cost price

$=(50)/(100) * x=(1)/(2) * x=(x)/(2)$

Selling price of running shoes = Cost price + Mark up amount

$75=x+(x)/(2) \n \n 75=(2* x+1* x)/(2) \n \n 75=(2x+x)/(2) \n \n 75=(3x)/(2) \n \n By\ cross\ multiplication\n \n 3x=75*2\n \n 3x=150\n \n By\ dividing\ both\ sides\ by\ 3\n \n x=50$

Thus, the store paid $50 for running shoes that are selling for $75.

Amelia measured the elementary school and made a scale drawing. The scale of the drawing was 11 millimeters : 4 meters. If the schoolyard is 484 millimeters long in the drawing, how long is the actual schoolyard?

Answers

Answer: 176m

Step-by-step explanation:

First we have to convert the meters in the scale to millimeters

4m = 4*1000mm

Now we got the scale 11:4000

11x = 4000 * 484
x= (4000*484)/11
x = 4000 * 44
x = 176000mm = 176m

176 meters
Ex: In the drawing 484 millimeters so 44x11 millimeters: 176

Answers

Answer:2

Step-by-step

7-(-1)/5-1=8/4 =2

Answer:

Step-by-step explanation:

The equation for slope is y2 - y1 / x2 - x1. So 7 - -1 / 5 - 1 equals 8 / 4. 8 / 4 is 2.
