187.775

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).

Step-by-step explanation:

Step 1: find the names of the two sides we know

triangle showing Opposite, Adjacent and Hypotenuse

Adjacent is adjacent to the angle,

Opposite is opposite the angle,

and the longest side is the Hypotenuse.

Example: in our ladder example we know the length of:

the side Opposite the angle "x", which is 2.5

the longest side, called the Hypotenuse, which is 5

Step 2: now use the first letters of those two sides (Opposite and Hypotenuse) and the phrase "SOHCAHTOA" to find which one of Sine, Cosine or Tangent to use:

SOH...

Sine: sin(θ) = Opposite / Hypotenuse

...CAH...

Cosine: cos(θ) = Adjacent / Hypotenuse

...TOA

Tangent: tan(θ) = Opposite / Adjacent

In our example that is Opposite and Hypotenuse, and that gives us “SOHcahtoa”, which tells us we need to use Sine.

Step 3: Put our values into the Sine equation:

Sin (x) = Opposite / Hypotenuse = 2.5 / 5 = 0.5

Step 4: Now solve that equation!

sin(x) = 0.5

Next (trust me for the moment) we can re-arrange that into this:

x = sin-1(0.5)

And then get our calculator, key in 0.5 and use the sin-1 button to get the answer:

x = 30°

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:

Angle ABE = 58

Step-by-step explanation:

This would fulfill the AAA theorem, or 3 angles needing to be congruent. We got 58 by subtracting 89 and 62 from 180, then multiplying that answer by 2 (because it occupies both triangles).

Answer:

local governments have the most power

Step-by-step explanation:

I hope this is right, but federalism gives more power to the state, so local governments could potentially have more power.

Answer:

i believe it is option one: power and authority are concentrated in the central government and can take away people’s rights

Step-by-step explanation: well i mean its true the governments are corrupted and are slowly taking away our rights

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

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:

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
