Answer:

The answer to your question is (3, 0)

Step-by-step explanation:

Data

              4x  +  2y  = 12                 Equation l

                x  -    y   = 3                   Equation ll

Process

To solve this problem use the elimination method

1.- Multiply equation ll by 2

              4x  +  2y  =  12

              2x  -  2y  =    6

              6x      0   = 18

2.- Solve for x

                        6x = 18

                          x = 18/6

                          x = 3

3.- Substitute x in equation ll to find y

                3  -  y  = 3

-Solve for y

                    -y = 3 - 3

                     y = 0

4.- Write the solution

                   (3, 0)

How do you write y=-4x^2-16x-14 in vertex form??
GREYUIT [131]

y= -4x² - 16x - 14


Take the coefficient of x² as the common factor

y = - 4(x² + 4x + 7/2)


Add (b/2)² to complete the square

y = - 4( x² + 4x + 2² - 2² + 7/2)


Complete the square

y = -4( (x + 2)² - 1/2)


Remove the bracket

y = -4(x + 2)² + 2


Answer: y = -4(x + 2)² + 2

What would be the answer to this
daser333 [38]
To solve, lets convert the number so that they both have the similar exponents.

2*10^{-24} =20000*10^{-28} &#10;&#10;

in comparing 20,000*10^-28 and 9*10^-28, we can see that one is nearly 2,000 times bigger than the other

20,000/9=2222

Answer= C

3+x=x^2+3x Rewrite the equation by completing the square. What are the solutions to the equation?
Luda [366]

Answer:

hope this helps

Step-by-step explanation:

3+x=x²+3x

Simply the equations.

= x+3=x²+3x

Subtract x²+3x from both sides.

x+3−(x²+3x)=x2+3x−(x²+3x)

−x2−2x+3=0

Factor left side of equation.

(−x+1)(x+3)=0

−x+1=0 or x+3=0

Answer:

x=1 or x=−3
