Answer:

I'll assume "S2x+3y=-12" is actually 2x+3y=-12 and that the question is to solve for x and y.

x = -(9/5)

y = -(14/5)

Step-by-step explanation:

2x+3y=-12

4x-4y=4

---

2x+3y=-12

8x+12y=-48  [Multiply the 1st equation by 4]

12x-12y=12   [Multiply the second equation by 3]

20x = -36     [Now we can add the two equations to remoce the y term]

x = -(36/20)  

x = -(9/5)       [The value for x]

====

2x+3y=-12        [Take either equation and s=use x=-(9/5) to find y]

2(-9/5)+3y=-12  

-(18/5) + 3y = -12

+ 3y = -12 + (18/5)

y = -4 + (6/5)

y = -(20/5)+(6/5)

y = -(14/5)          [This is the value of y that will work for both equations]

These equations both have the point (-9/5, -14/5) in common:  they intersect here.

This problem can also be solved by graphing each equation and finding the point they inersect on the graph (attached).

Answer:

Fourth Quadrant

Step-by-step explanation:

a>0 = a is a positive number = +y

b<0 = b is a negative number = -x

[-b,-a] = [-(-x), -(+y)] = [x, -y]

[positive, negative] is on the fourth quadrant

Answer:

9 puppies

Step-by-step explanation:

12*0.75=9

75% remains

Answer:

9

Step-by-step explanation:

Number of puppies before adoption = 12

[tex]Number \ of \ puppies \ adopted = \dfrac{25}{100}*12 = \dfrac{1}{4}*12 = 3[/tex]

Number of puppies that remain = 12 - 3 = 9

Answer:

X = -1 & and for some additional information Y = -5

Step-by-step explanation:

6 x (-1) = (-6)

5 x (-5) = (-25)

(-6) - (-25) = (-31)

_____________

5 x (-1) = (-5)

3 x (-5) = (-15)

(-5) + (-15) = 10

Answer:

  x = -1

Step-by-step explanation:

Rashid may have used elimination to solve the problem, but we can use any method we like to find the correct value of x. One method we like is graphing. The attached graph shows the solution is (x, y) = (-1, 5), so we know Rashid found ...

  x = -1

__

If we go down Rashid's path, we multiply the first equation by 3 and add that to the second equation multiplied by 5. (This choice of multipliers results in a positive coefficient for x.)

  3(6x -5y) +5(5x +3y) = 3(-31) +5(10)

  18x -15y +25x +15y = -93 +50 . . . . . . eliminate parentheses

  43x = -43 . . . . . . . . . . . . . . . . . simplify

  x = -1 . . . . . . . . . . . . . . . . . divide by 43

Answer:

$49,592.50

Step-by-step explanation:

First, to find the total fee of application you times 910 by $1.75 which will give you

910 × 1.75 = 1592.5

Then you add 48,000 with 1,592.5

which will give you an answer of

48,000 + 1,592.5 = $49,592.50

Answer:

(x,-y): (2,-2)

Step-by-step explanation:

M=(x+x)/2,(y+y)/2

Given (1,4)=

[tex] \frac{3x - 4}{2} [/tex]

This implies:

[tex]1 = \frac{3x - 4}{2} [/tex]

[tex]3x - 4 = 2 \\ 3x = 2 + 4 \\ \frac{3x }{3} = \frac{6}{3} \\ x = 2[/tex]

In a similar way,

[tex]4 = \frac{ - 2 + 5y}{2} \\ - 2 + 5y = 8 \\ 5y = 10 \\ y = 2[/tex]

The question demanded (x,-y)

Hence(2,-2) is the answer

Answer:

2/3

Step-by-step explanation:

Answer:

Let's solve by eliminating x. Since 18 is the lowest common multiple , let's multiply the first equation by 3 and the second by -2.

18x−21y=24

−18x+10y=−2

Add the two equations.

−11y=22

Divide by -11 to isolate y.

y=−2

Substitute y=−2 into either of the 2 equations, I'll just use the second one.

9x+10=1

9x=−9

x=−1
