Answer:
<u>8/10 hours or 48 minutes.</u>
Step-by-step explanation:
State the problem as a rule of 3:
3/4 room --------- 3/5 hours
1 room ------------ x

x= 0.8 hours.
• How much is 0.8 hours in minutes?

Answer:

Step-by-step explanation:
Given
See attachment
Required
Determine the slope of the line
From the attachment, we have the following points

and

The slope m is then calculated using:

Substitute values for the x's and y's




<em>Hence, the slope is 0</em>
Answer:
What? Hey no no no yes what no no yes what yes yes
The given quadratic describes a parabola that opens upward. Its one absolute extreme is a minimum that is found at x = -3/2. The value of the function there is
(-3/2 +3)(-3/2) -1 = -13/4
The one relative extreme is a minimum at
(-1.5, -3.25).
_____
For the parabola described by ax² +bx +c, the vertex (extreme) is found where
x = -b/(2a)
Here, that is x=-3/(2·1) = -3/2.
