When you have an equation that has variables and you know the value of those variables, just plug it it. So plugging the vaules we get
Just evaluating we get 4

1. Graph the function . Draw a chart to show at least four ordered pairs that are on the graph.
2 answers:
Simple...
you have:
Graph is attached.
Some ordered on this line are-->>
Using x y
(-4,-0.5)
(-3,-0.667)
(-2,-1)
(1,2)
(3,0.667)
(4,0.5)
Thus, your answer.

To sketch a given function, it is necessary that you must know it's domain first. Domain :- values of x for which function ( y) is defined. Here for x= 0, y is not defined so domain of this function is R- {0}. This graph is rectangular hyperbola. Other than this hope you are able to understand clearly... It's a bit messy.

Answer:
Step-by-step explanation:
To start calculating, we first need to make some proof.
Firstly, since AB = AC, we know that ΔABC is isosceles, which means that ∠ABC = ∠ACB.
Now, looking only to ΔBDE and ΔCDF, we can see that they are similar, because the two of its angles are congruent:
∠BED=∠CFD
∠DBE=∠DCF
To make it easier to visualize which are the corresponding vertexes, we can draw them like this:
And we need to remember that BC is 24, so:
BD+CD=24
Since the triangles are similar, their corresponding sides have constant ratio, which we can calculate from the corresponding sides DE and CF:
This ratio is the same for the other corresponding sides, so we can apply that for BD and CD:
Thus, the measure of CF is approximately 13, alternative D.
