Zack is purchasing a bag of apples. the cost of apples is proportional to the weight of the apples in pounds as shown on the graph.

which statements are true about the cost of the apples?

select each correct answer.

4 lb of apples will cost zack $10.

10 lb of apples will cost zack t $4.

1 lb of apples will cost zack $2.50.

2.5 lb of apples will cost zack $1.
graph titled cost of apples. the vertical axis is labeled weight in pounds. the horizontal axis is labeled cost in dollars. the horizontal x axis ranges from 0 to 10 in increments of 0.5. the vertical y axis ranges from 0 to 10 in increments of 0.5. a line passes through the origin and the points begin ordered pair 1 comma 2.50 end ordered pair and begin ordered pair 4 comma 10 end ordered pair.

Below are selected answers which are correct

10 lb of apples will cost Zack  $4.

1 lb of apples will cost Zack $2.50.

Step-by-step explanation:

Given:

Graph titled is Cost of Apples.

The cost of apples is proportional to the weight of the apples in pounds as shown on the graph.

Here the horizontal axis is labelled in cost in dollars.

And vertical axis is labelled weight in pounds,

Both axis range are from (0-10) with and increment of 0.5

The points given are (1,2.5) and (4,10),

from above points we get can say the equation will become;

when x = 1 y= 2.5 and when x=4 y = 10.

Hence we can say that,

10 lb of apples will cost Zack  $4.

1 lb of apples will cost Zack $2.50.

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
