Answer:

f(5) = - 8.

Step-by-step explanation:

There are two columns and 4 rows in the given table.

The first column is labeled x with different four entries and the second column is labeled f(x) with four different entries corresponding to the values of x since y = f(x).

The four ordered pairs are (-4,-2), (-1,5), (3,4) and (5,- 8).

So, from the fourth ordered pair, we can write f(5) = - 8. (Answer)

Answer:

<h2>The Slope Is 12</h2>

Step-by-step explanation:

Below are the steps to follow to find the slope of any line.

First you need to pick two points. I chose (2,24) and (4,48). (It does not mater what points you chose.)

Now follow the equation

Slope (m) = ΔY/ΔX

ΔY = 48 – 24 = 24

ΔX = 4 – 2 = 2

24/2 = 12

Then no mater what points you chose, 12 should be your final answer

Suppose y varies directly as x, and y=14 when x=4. What is the value of y when x=9

Katena32 [7]

Given :-

y varies directly as x, and y=14 when x=4.

To Find :-

the value of y when x=9 .

Solution :-

According to Question ,

y = kx ( k is constant )

When y = 14 and x = 4 ,

14 = k(4)
k = 14/4
k = 7/2

When x = 9 ,

y = 7/2*9
y = 63/2
y = 31.5
