Answer:

You have to graph and label the points

Step-by-step explanation:

3x-5 is just a straight line which is lesser than or equal to -1 so that is a closed circle

-2x+3 is another straight line which is (both open circle) which its domain is restricted from -1 to 4

2 is just a horizontal line starting at (closed circle) 4, it is greater than also.

If you don't understand the the constants (the numbers on their own) just a vertical translation.

If the cross either the x or y axis, you have to find that too, im pretty sure.

To find the y axis intercept, make x = 0 and solve for y

and to find the x axis intercept, make y = 0 and solve for x

We have 6 tents for 18 campers each tent holds 2 or 4 campers exactly how many of our tents hold 2

wolverine [178]

Answer:

3 tents hold 2 campers

Step-by-step explanation:

The given relations can be expressed as a single equation in the number of 2-camper tents.

Let x represent the number of 2-camper tents. Then the number of 4-camper tents is 6-x, and the total number of campers in tents is ...

2x +4(6 -x) = 18

-2x +24 = 18

-2x = -6 . . . . . . subtract 24

x = 3 . . . . . . . divide by -2

Exactly 3 tents hold 2 campers.

_____

<em>Additional comment</em>

The other 3 tents hold 4 campers.

Another way to consider this is to assume that all tents hold 2 campers, and then realize there are 18 -6×2 = 6 campers left over. If these are placed 2 per tent, then there will be 6/2 = 3 tents with 4 campers. The remaining 3 tents will have 2 campers.

Which expression is equivalent?

gregori [183]

The correct option is: Option (C) $log_3c - log_{3}9$

Explanation:
It is the property of log that if it contains the fraction, it can be expressed as the difference of the log of numerator and the log of denominator.

The general form is:
$log( \frac{x}{y} ) = log(x) - log(y)$

Hence the correct answer is $log_3c - log_{3}9$ .
