Answer:

y =(5,0,-3,-4,-3,0,5)

Step-by-step explanation:

To get y you have to replace the different number of x in the equation

For example,  

To x=-1

y=x^2-4x

y=(-1)2-4*(-1)=

y=5

to x=0

y=x^2-4x

y=0^2-4*0

y=0

The table will be:

x y

-1 5

0 0

1 -3

2 -4

3 -3

4 0

5 5

F(x) = x + 6 , find the ordered pair when x = -2.
ss7ja [257]

Answer:  \textsf{Option A, (-2, 4)}

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

Given:  \textsf{f(x) = x + 6}

Find:  \textsf{f(-2)}

Solution:  We need to plug in the value -2 into every variable x that we have in the expression and simplify to get the solution.

<u>Plug in the values</u>

  • \textsf{f(x) = x + 6}
  • \textsf{f(-2) = -2 + 6}

<u>Simplify</u>

  • <u />\textsf{f(-2) = -2 + 6}
  • \textsf{f(-2) = 4}

Therefore, the ordered pair that would match would have a x-coordinate of -2 and a y-coordinate of 4 producing (-2, 4) which matches option A.

Using the side-splitter theorem, which segment length would complete the proportion? startfraction g h over h e endfraction = st
iren2701 [21]

The ratio of gh over he is equal to the ratio of gj over jf. Then the correct option is C.

<h3>What is the triangle?</h3>

Triangle is a polygon that has three sides and three angles. The sum of the angle of the triangle is 180 degrees.

We know that the side-splitter theorem states that two triangles are similar if their corresponding angle is equal and the ratio of the corresponding will be the same.

\rm \dfrac{gh}{he} = \dfrac{gj}{jh}

More about the triangle link is given below.

3/4(n+3)=9 how do I find n
katrin [286]
It's one of the ways to count it:

3/4 (n + 3) = 9
3/4n + 3/4 * 3 = 9
3/4n + 9/4 = 9
3/4n + 2 1/4 = 9     / - 2 1/4 (both sides)
3/4n = 6 3/4     / : 3/4 (both sides)
n = 9
