The values in the table represent a function.

Hatshy [7]

Given:

The values in the table represent a function.

x f(x)

-2 1

1 3

4 -2

-3 0

0 4

To find:

Function notation for the ordered pair given in the first row in the table.

Solution:

We know that, if a point (a,b) is on the function, then $f(a)=b$ .

From the given table, the ordered pair given in the first row is (-2,1). So,

$f(-2)=1$

Therefore, $f(x)=1$ when $x$ is $-2$ .

Two mechanics worked on a car. The first mechanic worked for 5

ArbitrLikvidat [17]

<u>Answer:</u>

$50 and $115

<u>Step-by-step explanation:</u>

We know that,

the sum of the two rates = $165 per hour

Let x and (165 - x) represent the $/hour of the 15hr and 5hr mechanics respectively.

Then combining their charges together to get:

$(x*15)hour+(165-x)*5 hour=1325$

Solving for x to get:

$15x-5x+825=1325$

$10x=500$

$x=50$

So the rate charged per hour by one mechanic is $50 and for the other mechanic = $(165-50)=$ $115.
