9. Deanne works in a shoe factory. She packs pairs of tennis shoes and pairs of boots in
boxes to ship to shoe stores. The tennis shoes
weigh 2 pounds and boots weigh 5 pounds.
Each box can weigh a total of 50 pounds.

( explanations are mucho appreciated:) )

a. Assuming x represents the number of pairs
of tennis shoes and y represents the
number of pairs of boots, write an equation
to represent the situation.

b. What is the x-intercept, and what does it
represent?

c. What is the y-intercept, and what does it
represent?

a. 2x+5y=50

b. (25,0), the number of tennis shoes needed to weigh 50 pounds.

c.(0,10), the number of boots needed to weigh 50 pounds.

Step-by-step explanation:

a. Weight times number is what we are looking for to add up to the total weight of the shoes

b. set to y to 0

c.  set x to 0

it is x=-4

step-by-step explanation:

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
