Answer:

x = 120, y = 160

Step-by-step explanation:

I like to use the elimination strategy in this type of problem.

You need to get one of the terms on the right side of the equation equal to and opposite another term on the right side of the other equation. For example, I'm going to make the y term of the first equation equal and opposite the y term of the second equation by multiplying the entire first equation by -1.5.

-1.5 * (x + y) = (280) * -1.5

2.5x + 1.5y = 540

The new equations are (only the first one changed):

-1.5x - 1.5y = -420

2.5x + 1.5y = 540

-----------------------------------

x = 120

Then plug this back into one of the equations.

(120) + y = 280

y = 160

You can check by plugging these into the other equation to make sure they are correct.

So, adding a negative number is the same as subtracting.

4-3+5-2

Then if you want, you can use the associative property.
(4-3)+(5-2)
1+3

Graph the system of equations on graph paper.
MrRa [10]
Ths system of equations is

<span>8x+6y=48 ..............>y = 48/6 -8x/6
2x−3y=−6 ..............>y = 6/3 + 2x/3

If we use a graphic tool, we can easily check the solution, 
which is (x,y) = (3,4)

The ordered pair lies in Quadrant I

What is the polynomial function of lowest degree with lead coefficient 1 and roots 1 and 1 + i?
astra-53 [7]

x³ - 3x² + 4x - 2

complex roots occur in conjugate pairs

1 + i is a root then so is 1 - i

the factors of the polynomial are therefore

f(x) = (x - 1 )(x - (1 + i))(x - (1 - i))

     = (x - 1 )(x² - 2x + 2 ) ( expand factors and simplify )

     = x³ - 3x² + 4x - 2
