Answer:
C , 6/15
Step-by-step explanation:
Hope it helps !!:)
Area =l×w
15.4=7×w
15.4/7=7/7w
2.2=w
Therefore the length of the height or width is 2.2ft
You can see the side conditions for the function. We read the x CANNOT be 4. See it?
We evaluate the bottom piece at x = 4. Let's do that.
f(x) = -2x
Let x be 4.
f(4) = -2(4)
f(4) = -8
What about the other piece?
Evaluate the top piece at x = 2.
Let's do that.
f(x) = 3x
Let x be 2.
f(2) = 3(2)
f(2) = 6
Answer: Choice D
Did you follow? It is a piecewise function. Solve it one piece at a time keeping each side condition in mind along the way.
Answer: 13 units is the distance between the points.
The answer is D, 21 to 140
21 to 140 can be written as
So if you multiply
by
, you get
.
