−5 ≤ x ≤ 20

all real numbers

x ≥ 0

Answers

y = 2x² + 30x + 200
y = 2(x² + 15x + 100)

x² = x*x
100 ⇒ 1 x 100 ; 2 x 50 ; 4 x 25 ; 5 x 20 ; 10 x 10

200 = 2x² + 30x + 200
0 = 2x² + 30x + 200 - 200
0 = 2x² + 30x + 0
0 = 2(x² + 15x + ?)

4x + 2y = 11
x - 2 = -2y
First you have to get a variable alone in one of the equations.

x - 2 = -2y
   +2    +2
--------------
x = -2y + 2
Next you substitute -2y +2 for x in the second equation.

4(-2y + 2) + 2y = 11
Distribute. 

-8y + 8 + 2y = 11
Combine like terms.

-6y + 8 = 11
Get the variable (y) by itself.

-6y + 8 = 11
       -8    -8
--------------------
-6y = 3
Finally get y by itself.

-6y = 3
-----   ------
-6      -6

Y = 0.5

Now to get x you plugin the answer for y.

x - 2 = -2y
x - 2 = -2(0.5)
x - 2 = -1
   +2     +2
x = 1

(1, 0.5) Is your ordered pair. :D

Answer: (x)/(2) + (31y)/(2)

Step-by-step explanation:

1) Combine multiplied terms into a single fraction.

(1)/(2) x + (31)/(2) ⋅ y

2) Multiply the equation by 1.

1x/2+ 31/2 ⋅ y

x/2 + 31/2 ⋅ y

3) Combine multiplied terms into a single fraction.

x/2 + 31/2 y

x/2 + 31y/2

4) Solution

x/2 + 31y/2
