Elena-2011 [213]

Answer:

It will cost $700 to play the entire schedule.

Step-by-step explanation:

Given : $N(x)=x^2-x$

To Find : A softball league has 5 teams, each of which play the others twice. If the league pays $35 per game, how much will it cost to play the entire schedule?

Solution:

Equation for total no. of games when all the teams play each other twice is $N(x)=x^2-x$

Now we are given that A softball league has 5 teams, each of which play the others twice.

So, Substitute x = 5 in the given equation

$N(x)=5^2-5$

$N(x)=20$

So, The total no. of games = 20

Cost for 1 game = $35

So, cost for 20 games = $35 \times 20 = 700$

Hence it will cost $700 to play the entire schedule.

2x + 2 y = -2<br> 3x - 2y = 12

Serggg [28]

Answer:

x=2 and y=-6 aka. (2,-6) which is the point of intersection

Step-by-step explanation:

Use elimination to cancel out y by adding the equations:

5x=10

x=2

Plug x=2 into one of the equations and find y:

2(5)+2y=-2

10+2y=-2

2y=-12

y=-6

Therefore, x=2 and y=-6

(−3p2+5p−2)+(−p2−8p−15)=

Blizzard [7]

Answer:

Step-by-step explanation:

When you distribute a positive sign to a parentheses, you essentially change nothing. So, you can drop all of the parentheses for this entire equation. Now combine like terms.

$-4p^2-3p-17$

$-1(4p^2+3p+17)$
