10x -15y=45
9x+15y= 12

19x= 57
x= 3

3(3)+5y= 4

9 + 5y = 4
5y = -5
y = -1

(3,-1)

What is the interquartile range of 77 88 92 81 86 84 86 83 and how do you get it thx plz help

puteri [66]

To find the IQR you first need to write it in numerical order

77, 81, 83, 84, 86, 86, 88, 92

IQR is just Q3 - Q1

Q1 is the middle of the first have, since it has an even set of 4 numbers in the first half you need to take the average of the two middle ones.. which is 82

Q3 done the same process would be 87.

87 - 82 = 5

IQR = 5

Graph y< 1/3 c + 1/2

castortr0y [4]

<h3>The Graph you need above </h3>

<h3>Step-by-step explaination : </h3>

<h3>Combine 1/3and x.</h3>

y<x/3+1/2

<h3>Use the slope-intercept form to find the slope and y-intercept.</h3><h3 />

Slope: 1/3

y-intercept: 1/2

<h3>Graph a dashed line, then shade the area below the boundary line since y is less</h3><h3>than x/3+1/2.</h3>

Anser number 6 for me so i kan get a better grade

Arlecino [84]

Answer:

Rita is left with approximately $\$ 4$

Step-by-step explanation:

Given:

Price for trousers= $\$ 19.39$

Price for shirt = $\$ 27.88$

Price for headscarf = $\$ 8.62$

Total Money she Spent = Price for trousers + Price for shirt + Price for headscarf = $\$ 19.39 + \$ 27.88+ \$ 8.62 = \$55.89$

Total Money she had before = $\$60$

∴Total Money left = Total Money she had - Total Money she spent = $\$60 - \$55.89 = \$4.11$

Rounding to nearest whole number ≈ $\$4$

Estefani‘s house is at point E (3,-2) and Jasmin’s house is at point J (-5,3). Jasmin’s house is the Mid-point of Estefani’s hou

iren [92.7K]

The formula for midpoint is

( $\frac{x_{1}+x_{2}}{2}$ , $\frac{y_{1}+y_{2}}{2}$ )

Look at the image below to see the line segment of Estefani's (A), Jasmin's (M), and Preston's (B) houses. Keep in mind that the segment shown below is not accurate in regards to how the line segment formed by Estefani's, Jasmin's, and Preston's houses. It is simply there so you can picture the segment better.

In this case:

$x_{1} =3\\x_{2} =unknown\\y_{1} =-2\\y_{2} =unknown$

^^^Plug in these number into the formula given above...

( $\frac{3+x}{2}$ , $\frac{-2 + y}{2}$ )

To find what x is (a coordinate of Preston's house) you must take the x-value part of the midpoint equation ( $\frac{3+x}{2}$ ) and set it equal to the x-value of the midpoint (-5). Then you must solve for x:

$\frac{3+x}{2}$ = -5

3 + x = -5 * 2

3 + x = -10

x = -10 - 3

x = -13

To find what y is (a coordinate of Preston's house) you must take the y-value part of the midpoint equation( $\frac{-2 + y}{2}$ ) and set it equal to the y-value of the midpoint (3). Then you must solve for y:

$\frac{-2 + y}{2}$ = 3

-2 + y = 3 * 2

-2 + y = 6

y = 6 + 2

y = 8

The coordinate of Preston's house is:

(-13, 8)

Hope this helped!
