1 answer:
Artemon [7]3 years ago
3 0

Answer:

c

Step-by-step explanation:

There is 6 students in the 8hr zone.

Gosh, do I have to explain?  A is a, c is c!

4+6+6+6.5+6.5+6.5+6.5+7+7+7+7+7.5+7.5+7.5+8+8+8+8+8+8.5=141.

141÷20=7.05. So, no, it is not b.

I want only question number 3
zmey [24]

Answer:

Computers R Us has a better price because it cost less at the same production rate.

Step-by-step explanation: to graph y=23.5x you just plug in numbers. If x = 1, 23.5 (1), which equals y. Now you can keep doing this to get up to 4. You may use a calculator if youd like.

What is the domain of the function graphed below?
I am Lyosha [343]

Answer:

x < 7

Step-by-step explanation:

the domain is the number range or interval of x the function is defined for to generate a y-value.

the graph shows that the y-values continue with x-values to the right up to but not including 7 (the empty dot says "excluding"). and with x- values to the left to negative infinity.

x=-1 is not a problem, because while for the left part of the function it is not included, but for the right part it is.

so, it is fully defined for all x < 7.
