If f(2)=9 and f(-1)=14, write a linear function that fits this scenario. Be sure to use proper notation. HELP!!
olya-2409 [2.1K]

Answer:

The required linear function is: f(x) = $ \frac{-5}{3}x + \frac{37}{3} $

Step-by-step explanation:

We are given that f(x) is a linear function and it takes the value 9 when x = 2 and 14 when x = -1.

Now the general form of any linear function is: f(x) = ax + b.

Substituting these values in the general form we get:

f(2) = 9  = 2a + b

f(-1) = 14 = -a + b

Solving these two equations we get:

b = 37/3

Substituting this in the second equation to find 'a'.

a = -5/3

Therefore, the function f(x) = $ \frac{-5}{3} $x + $ \frac{37}{3} $.

A CD makes 58 1/2 revolutions in 3/4 min.
shusha [124]
The most important thing in this problem is understanding and then dividing the given units properly. The first thing that is given is that the CD makes 58 1/2 revolutions in 3/4 minutes. We have to first simplify the number of revolutions made by the CD. This will make the problem in hand very easy.
Number of revolutions made by the CD = 58 1/2
                                                               = 117/2
Then
The unit rate = (117/2)/(3/4)
                     = (117 * 4)/(2 * 3)
                     = (117 * 2)/3
                     = 39 * 2
                     78
So the unit rate is 78 revolutions per minute.
