Alinear function that represents the number of video games purchased at an electronics store is compared to a different linear function that represents the amount of money the store made that day. describe the key features of the functions that are needed to determine if these lines intersect.

Let total number of video games purchased from electronics store = m

 So,→ x=m,or y=m, Represents linear equation which represents number of video games purchased.(1)

For purchasing, m video games ,let amount of money spent is given by

     →y=mx, x is amount of money spent on buying a single video game.

                         (2)

Equating (1) and (2)

→One line is Passing through origin and another line cuts either x axis at (m,0) or y axis at point (0,m).

So, there will be one point of Intersection of these two intersecting lines.

If all variables represent real numbers you can graph the equation by plotting enough points to recognize a pattern and then connect the points to include all points.

Step-by-step explanation:

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
