Solve by the linear combination method (with or without multiplication) <br> 2x+3y= -17, 5x+2y = -4
Amiraneli [1.4K]
2x+3y= -17 
5x+2y= -4
You must cancel either the x or y out to solve so i'm going to cancel the x. 
-5(2x+3y= -17)
2(5x+2y= -4)
This simplifies to: 
-15x -15y=85
15x+4y= -8
The -15x and 15x cancel out leaving you: 
-15y=85 
4y= -8
You add them top numbers by the bottom and get: 
-11y=77
Then divide by -11 to get y by its self.
y= -7
Now that you know what y is just plug it in to either original problem. I will use the second one. 
5x + 2(-7) = -4
5x -14 = -4
5x = 10 
x = 2
So the answer is (2,-7) or x=2 and y=-7

(2x^3+9x^2+x-12)/(x+4) simplify
neonofarm [45]

Answer:

<h2>2 {x}^{2}  + x - 3</h2>

Step-by-step explanation:

\frac{2 {x}^{3}  + 9 {x}^{2}  + x - 12}{x + 4}

Write 9 {x}^{2} as a sum

\frac{2 {x}^{3}  - 2 {x}^{2} + 11 {x}^{2}   + x - 12}{x + 4}

Write X as a sum

\frac{2 {x}^{3}  - 2 {x}^{2} + 11 {x}^{2} - 11x + 12x - 12  }{x + 4}

Factor out 2 {x}^{2} from the expression

\frac{2 {x}^{2}(x - 1) + 11 {x}^{2} -  11x + 12x - 12  }{x  + 4}

Factor out 11x from the expression

\frac{2 {x}^{2} (x - 1) + 11x(x - 1) + 12x - 12}{x + 4}

Factor out 12 from the expression

\frac{2 {x}^{2}(x - 1) + 11(x - 1)  + 12(x - 1) }{x + 4}

Factor out X - 1 from the expression

\frac{(x - 1)(2  {x}^{2}   + 11x + 12)}{x + 4}

Write 11x as a sum

\frac{(x - 1)(2 {x}^{2}  + 8x + 3x + 12)}{x + 4}

Factor out 2x from the expression

\frac{(x - 1)(2x(x + 4) + 3x + 12)}{x + 4}

Factor out 3 from the expression

\frac{(x - 1)(2x(x + 4) + 3(x  + 4)}{x + 4}

Factor out X + 4 from the expression

\frac{(x - 1)(x + 4)(2x + 3)}{x + 4}

Reduce the fraction with X + 4

(x - 1)(2x + 3)

Multiply the parantheses

2 {x}^{2}  + 3x - 2x - 3

Collect like terms

2 {x}^{2}  + x - 3

Hope this helps...

Good luck on your assignment...

FIND THE AREA OF THE REGULAR POLYGON. ROUND TO THE NEAREST TENTH. <br><br> HELP IM CONFUSED!!
Alex17521 [72]

Answer:

half the diagonal is given as 7 yards, the full diagonal would be 7 x 2 = 14 yards.


The formula for the length of a side of a square using just the diagonal is:

Side = √2(d/2)

Side = √2 (14/2)

Side = √2(7)

Side = 9.9 yards.


The area of a square is S^2

Area = 9.9^2

Area = 98.01

Area = 98.0 Yards^2
