Answer:

(11/4) is the slope

Step-by-step explanation:

1) Subtract the second y value (-9) by the first y value (2) in the coordinates. This equals 11.

2) Then, subtract the second x value (-3) by the first x value (1) in the coordinates. This equals 4.

3) Divide the answer you get for step one by the answer for step 2 and that's your slope. 11/4

Step-by-step explanation:

Hey there!

The given points are; (1,2) and (-3,-9).

Use slope formula for finding the slope.

$slope(m) = \frac{y2 - y1}{x2 - x1}$

Put all values.

$m = \frac{ - 9 - 2}{ - 3 - 1}$

Simplify it.

$m = \frac{ - 11}{ - 4}$

Therefore, the slope is m= 11/4.

Hope it helps...

Suppose you like to keep a jar of change on your desk. Currently, the jar contains the following: 22 Pennies 27 Dimes 9 Nickels

kap26 [50]

Answer:

$P(Penny\ and\ Dime) = \frac{9}{116}$

Step-by-step explanation:

Given

$Pennies = 22$

$Dimes = 27$

$Nickels = 9$

$Quarters = 30$

Required

$P(Penny\ and\ Dime)$

This is calculated as:

$P(Penny\ and\ Dime) = P(Penny) * P(Dime)$

Since it is a selection without replacement, the computation is:

$P(Penny\ and\ Dime) = \frac{Penny}{Total} * \frac{Dime}{Total-1}$

So, we have:

$P(Penny\ and\ Dime) = \frac{22}{22+27+9+30} * \frac{Dime}{22+27+9+30-1}$

$P(Penny\ and\ Dime) = \frac{22}{88} * \frac{27}{87}$

$P(Penny\ and\ Dime) = \frac{1}{4} * \frac{9}{29}$

$P(Penny\ and\ Dime) = \frac{9}{116}$

Your class goes to an amusement park. admission is $10 for each student and $15 for each chaperone. the total cost is $380. ther

andrey2020 [161]

You would multiply the students by the price (12*10=120) then multiply chaperones by price (6*15=90) then add both prices together to get 210. Then you would subtract 210 from 380 to get how many boys are in the class. 380-210=170. Since each student cost 10 so you would divide 170/10=17. There would be 17 boys in your class.

maria buys 8 1/3 pounds of beef to make tacos for a party .She uses 5/9 pound of beef for each toco. how many tacos can maria ma

Olin [163]

Just do 8 1/3 divided by 5/9 or

25/3 / 5/9

25/3 * 9/5 = 5/1 * 3/1 = 15

So 15 tacos

* = times

/ = divided by
