Answer:

x=-1

y=15

Step-by-step explanation:

This works because completing the square is essentially demonstrating what g(x) - where g(x) in this case = x^2 - would have to be translated by to give the function you have.

So by completing the square you have shown that the function you've been given has been shifted to the left by -1, stretched by a factor of 2 along the y axis and shifted up by 15.

What's 6 1/3 + 5 1/2 + 4 1/4=

Art [367]

Answer:

16 1/12

Step-by-step explanation:

The LCD of 6 1/3 + 5 1/2 + 4 1/4 is 12; 12 is evenly divisible by 3, 2 and 4.

We can rewrite this expression as:

6 + 5 + 4 + 1/3 + 1/2 + 1/4, or

15 +4/12 + 6/12 + 3/12, or

15 + 13/12, or

16 1/12

Solve using substitution x = 3y + 1 2x + 4y = 12

Free_Kalibri [48]

Answer:

x = 4

y = 1

Step-by-step explanation:

x = 3y + 1 (Multiply everything by -2)

2x + 4y = 12 (Transfer 4y to the right of the = sign)

2x = -4y + 12

-2x = -6y - 2

0 = -10y + 10

-10 = -10y

y = 1

x = 3y + 1

x = 3(1) + 1

x = 3 + 1

x = 4

Which statements are true from the graph ? Check all that apply:

Flura [38]

The statements that are true from the graph are:

The line is horizontal
The line goes through (4, 4 )
The y- values are all 4

<h3>Calculations and Parameters</h3>

Given the graph, we can note some things:

There is a line with a slope of zero.
This is a horizontal line parallel to the x-axis.
The equation of the line is y = c

c is the value of the y- coordinates the line passes through.

The line passes through (0, 4 ) with a y- coordinate of 4

Therefore, the equation of the line of y= 4
