Answer:

y = -2444.4444x+19000

Step-by-step explanation:

Pick two points along the line to find the slope

(0, 19000) and (4.5, 8000)

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

        = (8000-19000)/(4.5-0)

         =-11000/4.5

           = -2444.44444444

We know the y intercept (where it crosses the y axis  (x=0))  (0, 19000)

We can write an equation using y = mx+b

y = -2444.4444x+19000

Using 2 points: (0,19,000) and (3.25, 11,000)


First find the slope by putting the change in Y over the change in X:

Slope = ( 19000 - 11000) / (0 - 3.25)

Slope = -2462.54


The Y intercept is the 1st Y value = 19,000


The equation becomes: y = -2461.54x + 19000

during one month the orangevale parks and recreation district spent $5720 for various activities. they spent $1430 on mommy and
AysviL [449]

To solve this problem, we must figure out what percent of the total spending was spent on mommy and baby exercise programs. To figure this out, we should divide how much was spent on the mommy and baby exercise by the total amount spent on the district activities.

$1430/$5720 = 0.25

This is a percentage, or a portion out of 100, which means we must multiply this decimal by 100 to find its equivalent percentage.

0.25 * 100 = 25

Therefore, your answer is 25% of the total spending was spent on mommy and baby exercise programs.

Hope this helps!

Solve and check 8-(6-8x) =4x+4
navik [9.2K]
Greetings!

"Solve and check 8-(6-8x)=4x+4"...

Solve for x<span>:
</span>8-(6-8x)=4x+4
Remove the Parenthesis.
8-6-8x=4x+4
Simplify.
2-8x=4x+4
Add -4 to both sides.
(2-8x)+(-4)=(4x+4)+(-4)
Simplify.
-2-8x=4x
Add 8x to both sides.
(-2-8x)+8x=(4x)+8x
Simplify.
-2=12x
Divide both sides by 12.
(-2)/12=(12x)/12
Simplify.
-0.166666667=x

The answer is: <em>x=-0.166666667

</em>Hope this helps.

Answer:

hello your question is incomplete attached below is a the complete question

answer : n = 5

Step-by-step explanation:

lets consider N to be 5

To prove that the least number 'n' = 5

we will represent this information in a graph as vertex

Black edge = Friends

Blue edge = not Friends

From the attached diagram any  vertex contains 0,1,2,3,4 black lines and 4,3,2,1,0 blue lines

attached below is an explanation related to the choice of n = 5

considering n = 5 is satisfied by the explanation given
