Margaret [11]

Answer: they can rent the room for less than 6 hours.

Step-by-step explanation:

Let x represent the possible amounts of time in which they can rent the room.

There is a reservation fee of $47 and an additional hourly fee of $7.40. This means that the total cost of renting the room for x hours would be

47 + 7.4x

The math club wants to spend less than $91.40 on renting the room. This would be expressed as

47 + 7.4x < 91.4

7.4x < 91.4 - 47

7.4x < 44.4

x < 44.4/7.4

x < 6

In (r,theta), the value of theta can be negative.<br>True or False
Marizza181 [45]

(r,theta) represents polar coordinate .

And in (r,theta), there is neither any restriction on r nor on theta. It means both r and theta can either be positive or negative .

For e.g. (2,30 degree), (2,-30 degree) both are correct .

So the given statement is true .

PLZ Answer ASAP!!!
Sliva [168]

Answer:

D. x = 3

Step-by-step explanation:

The only way we could get a line of symmetry through this figure is to use a vertical line.  The only way to get symmetry would be to put the vertical line though the point x = 3.  When we do that, we can see that the end points of the base are both one unit away from the line of symmetry.  The end points I'm talking about are the points at the coordinates (2, 4), and (4, 4)
