The following chart shows the number of rows in an auditorium and the total number of seats. What equation defines the number of
Anastaziya [24]

Answer:

<em>Answer: c) S=20R+60</em>

Step-by-step explanation:

<u>Linear Model</u>

The chart supplied shows the number of rows (R) in an auditorium and the total of seats (S).

We'll find the equation that relates them. The equation of a line can be expressed in the slope-intercept form:

S = mR + b

Where m is the slope and b is the intercept.

The slope is found by:

\displaystyle m=\frac{S_2-S_1}{R_2-R_1}

We'll use two sample points (20,460) and (45,960):

\displaystyle m=\frac{960-460}{45-20}=\frac{500}{25}

m = 20

The value of b can be found by using one of the points, for example (20,460), and having m=20:

460 = 20*20 + b

Thus: b = 460 - 400 = 60.

The equation is:

S = 20R + 60

You can test the other points and check they belong to the same line.

Answer: c) S=20R+60

Which fraction is equal to 5/6? 8/22, 25/30, 5/15?
nadya68 [22]
If the fraction cannot be simplified any more, you can multiply both the numerator and denominator by an number.

5/6 (multiply the top and bottom by 2) is the same as 10/12
8/22 (can be simplified by dividing top and bottom by 2) is 4/11
25/30 (simplified by dividing by 5) is 5/6
5/15 (simplified by dividing by 5) is 1/3

Hope this helps!

Please help!! Evaluate the piece wise function at x=-4 and x=4.
hodyreva [135]

x = -4, so use the first equation, x^2 = -4^2 = -16

x = 4, use 3rd equation, sqrt(x) = sqrt(4) = 2
