The graph shows the relationship between pounds of dog food and total cost, in dollars, for the dog food.
Which statement(s) about the graph is/are true?
A Point(0, 0) shows the cost is so for 0 pound of dog food
B. Point (1.05) shows the cost is $1 for 0.5 pound of dog food
C. Point (2, 1) shows that 2 pounds of dog food cost $1.
D. Point (42) shows the cost is $4 for 2 pounds of dog food
E Point (10.5) shows that 10 pounds of dog food costs $5.

answer: ♡♡♡♡♡♡♡♡♡♡

step-by-step explanation:

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."

"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.
