Answer:

r = -1

Step-by-step explanation:

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

(r,7)=(x1,y1) and (3,4)=(x2-y2) and m=-3/5

so plug in...

(4-7)/(4-r)=-3/5

then solve for r which will get that r = -1

numerator: 4-7=-3

denominator: 4-r=5 -> 4-5=0+r -> -1=r

Neporo4naja [7]

Answer:

Using the info you just gave,

Basketball, 8 studentsfootball, 7 studentsSoccer 12 studentsother, 13 students

We can now figure out the percentage of students that did NOT select soccer.

First, you need to add all the students together.

8 + 7 + 12 + 13

You get 40 students all together.

Now, add together the students that DID NOT choose soccer.

7 + 8 + 13 = 29

That means that 28/40 of the students did not choose soccer.

Now, convert that to a percentage.

28/40 = 0.7

To make that into a percentage, multiply by 100

Thus, the percentage of students that did not select soccer is 70%.

Hope this helped!

Jerrica is selling calendars to raise money for a community group she belongs to. A basic calendar sells for $10 and a deluxe ca

Sidana [21]

The correct answer is option B.

Let the basic calendars be = x

Let the deluxe calendars be = y

Total calendars are = 72 , so equation becomes:

$x+y=72$ .............(1)

Cost of 1 basic calendar = $10

So, cost of all basic calendars will be = 10x

Cost if 1 deluxe calendar = $15

So, cost of all deluxe calendars = 15y

As given, the number of deluxe calendars must be greater than or equal to 3 times the number of basic calendars, the equation becomes

y=3x ...............(2)

Putting the value of y from (2) in (1)

$x+y=72$

$x+3x=72$

$4x=72$

x=18

As, y=3x

y= $3\times18=54$

So we have 18 basic calendars and 54 deluxe calendars.

Cost of 18 basic calendars will be= $18\times10=180$

Cost of 54 deluxe calendars will be = $54\times15=810$

So total amount is = $990

Hence, the maximum revenue is $990.
