$\frac{x}{4} = -8$

Multiply 4 from both sides

$\frac{x}{4} *4=-8*4$

Simplify

$x = -32$

What is the probability that Jim, Bruce, Valerie, and Simon are selected in that order

irinina [24]

The first person can be chosen in 4 different ways.

The second person can be chosen in 3 different ways.

The third person can be chosen in 2 ways

The last person can only be chosen in 1 way.

4 * 3 * 2 * 1

there are 24 different ways that this can be done.

There is only 1 correct order.

The answer is 1/24 ways. 1/24 = 0.04166666

One positive number is 1/5 of another number the difference of the two numbers is 72 find the numbers

SpyIntel [72]

Let x be the lowest positive number Then the other number = 5x.

So 5x - x = 72

4x = 72

x = 18

So the numbers are 18 and 90 answer

Find the perimeter of the polygon with the given vertices. C(4, -1), D(4,−5), E(2,−3)

Aleksandr [31]

Answer:

8 units

Step-by-step explanation:

find the distance of the lines through coordinates given

distance formula: $\sqrt{(x_{1}-x_{2})+(y_{1} -y_{2} ) }$

i) CD= $\sqrt{(4-4)^2 +(-1+5)^2}$

CD= $\sqrt{0+4^2}$

CD=4 units

ii) DE= $\sqrt{(4-2)^{2}+(-5+3)^2 }$

DE= $\sqrt{(2)^2+(-2)^2}$

DE= $\sqrt{8}$

DE= 2 units

iii) ED= $\sqrt{(2-4)^2+(-3+1)^2}$

ED= $\sqrt{(-2)^2+(-2)^2}$

ED= $\sqrt{8}$

ED= 2 units

perimeter of polygon= 2 units+ 2 units+ 4 units

=8 units

KA AGAIN ( 2 pdfs)<br> correct answers only

Reil [10]

Answer:

Step-by-step explanation:

To find the constant of proportionality between y and x, divide $\frac{y}{x}$ for all given values of the chart. If you get the same number, then that is the constant. If they are all different numbers, then one does not exist for that function.

Using the method above, you should get:

Chart A = 2/5

Chart B = 1/5 (Correct Answer!)

Chart C = N/A

Hope this helps!
