Discrete domains and continuous domains are both sets. However a discrete domain contains a finite number of elements and continuous can contain and infinite number of elements.
Answer:
y = -2x - 8
Step-by-step explanation:
We want to find the slope-intercept form of this equation. Slope-intercept form is denoted by: y = mx + b, where m is the slope and b is the y-intercept.
We already know that the slope is -2, so that means m = -2.
We also know the y-intercept (or the point where the line crosses the y-axis) is (0, -8), which means b = -8.
Thus, our equation is: y = -2x - 8.

Answer:
3d - 4f
Step-by-step explanation:
(12d + 28f) - 5f - (27f + 9d)
12d + 28f - 5f - 27f - 9d
(12-9)d + (28-5-27)f
3d - 4f

Answer:
<em>The speed of a boat in still water is 6 miles per hour. </em>
Step-by-step explanation:
t = 
(upstream)
t = 
(downstream)
=
40 ( s - 2 ) = 20 ( s + 2 )
40s - 80 = 20s + 40
20s = 120
s = 6 mi / h
<em>The speed of a boat in still water is 6 miles per hour.</em>
