How would you solve x + 3y = 18 -3x - 12y = -75 showing all of the work
VikaD [51]

Answer:

x = -3, y = 7.

Step-by-step explanation:

 x + 3y = 18  

-3x -  12y = -75

Multiply the first equation by 3:

3x + 9y = 54

Adding the last 2 equations to eliminate x:

-3y = -21

y = 7.

Substitute y = 7 into the first equation:

x + 3(7) = 18

x + 21 = 18

x = 18 - 21

x = -3.

Write an equation of the line that has a slope of 2 and goes through (4, -1).
maxonik [38]

Answer:

y = 2x - 9

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 2, thus

y = 2x + c ← is the partial equation

To find c substitute (4, - 1) into the partial equation

- 1 = 8 + c ⇒ c = - 1 - 8 = - 9

y = 2x - 9 ← equation of line

There is a 3 out of 20 chance that you can win a game. How many "wins" would you predict if you played the game 50 times?
Virty [35]

Answer:

7.5

Step-by-step explanation:

The probability of winning = 3 out of 20 ;

P(winning) = 3/20

Predicted Number of winnings if game is played 50 times ;

P(winning) * number of games played

(3 /20) * 50

0.15 * 50

= 7.5

Predicted Number of winnings = 7.5

nalin [4]
First you make an equation and establish a variable.
x=amount of hours the DJs will charge the same amount
100+21x=150+15x
Now you solve for x and that will get you your answer.
100+21x=150+15x
-21x -21x
100=150-6x
-150 -150
-50=-6x
8.3333...=x
You can round the answer to $8.33
Hope I helped.
