On a scale 3 cm is 8 miles. If the actual distance is 28 miles, how many cm is this on the scale?

10.5

Step-by-step explanation:

10.5 cm

Step-by-step explanation:

First, the unit rate is .375 cm, because 3/8 = .375, so to find your answer you need to do .375 x 28 which = 10.5 cm.

Hope this helps!

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.

i did it myself and i got 4.2 (b) hope its right
