For each of the following, decide if the expression is "always countable", "always uncountable", "sometimes countable, sometimes uncountable". for the "always" cases, prove your claim. for the "sometimes" case, provide two examples – one where the expression is countable, and one where the expression is uncountable.

17 1/3

step-by-step explanation:

(-5,-28)

i graphed to on desmos.

its the second choice.

step-by-step explanation:

the elements in the range will be 7 less than the elements in the domain.

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
