+ use t for the number of hours the meeting room is rented
+ college charges a reservation fee of $47 and an additional fee of $5.40 per hour.So we have 47+ 5.40t
+ and the film club wants to spend less than $74.00 on renting the meeting room.So we need 47+ 5.40t<74
or 5.40t< 74-47
and 5.40t<27 we have t< 27:5.40=5
So the possible amounts of time for which they could rent the meeting room less than 5 hours

What is the equation of the line that passes through the point (5, -6) and has a slope of 3/5

Marysya12 [62]

Answer:

y = 3/5x + -9

or y = 3/5x - 9

Step-by-step explanation:

Since you are already given the slope for this equation all you have to do is plug in the ordered pair in this equation: y = mx+b

Here is what this equation stands for:

y = the y in the order pair you are given, in this case it would be -6

m = This is the slope, sometimes you may not be given the slope so you would have to find it, but in this case, you are given it, the slope is 3/5

x = the x in the ordered pair you are given, in this case it would be 5

b = This is the y-intercept, you will mostly be solving for this most of the time

(5,-6)

(x, y)

y = mx+b (Use this Formula)

-6 = 3/5(5) +b (The numbers have been substituted within the formula)

-6 = 3+b (simplify the equation by multiplying the slope by the x)

-6-3 = b ( once simplified the left side of the equation, go to the right side, but remember when you do that you have to change the sign because you are eliminating 3 on the left side completely, "what you do on one side, do it to the other side")

-9 = b (solve)

y = 3/5x + -9 (plug in the slope and B(y-intercept) within the formula - y = mx+b, make sure that you are not plugging in x and y for this step)

I Hope This Helped You Understand this Problem Better/More!!! Stay Safe and Healthy!

Construct an inscribed circle in triangle PQR by finding the incenter of the triangle.

hodyreva [135]

Answer:

Check it below

Step-by-step explanation:

Hello!

By definition, the intercept of the 3 bisectors, within a triangle is the Incenter. So let's get started, by tracing three bisectors.

In the triangle PQR::

Use a compass, open its legs with a little more than half of $\overline{PQ}$ . Place the needle point in the vertex of P. Mark!
Do the same, placing the needle point in Q, following $\overline{QP}$ direction. Mark
Repeat it with the other triangle's line segment, namely:
