Mathematics

2y is in the first equation so if you change 0.5x+y=17 to y=17-0.5x and then double it to 2y=34-x, you can  substitute and find x. And then you can find out y.

How to find x:

0.5x+y=17

y=17-0.5x

2y=34-x

3x-2y=8

3x-34-x=8

<u>x=21</u>

How to find y (with previous info.)

x=21

3x-2y=8

3*21-2y=8

63-8=2y

55=2y

<u>27.5=y</u>

An insurance company charges Ted E. Bear $1400 per year for insurance on his home. The company has predicted that there is a 10%
Anna35 [415]

Answer:

$900  

Step-by-step explanation:

The given parameters are;

The amount Ted pays per year for insurance on his home = $1,400

The value of the insurance policy = $5000

The chance that Ted will make a claim on the policy = 10%

The expected value is given as follows

Incidence                     Probability(p)        Value(v)                                   v × p

A claim is made            0.1                  $5,000 - $1,400 = -$3,600     -$360

No claim                        0.9                 $1,400                                       $1260

Expected value is $1,260 - $360 = $900

The value the insurance company can be expected to make on average on the policy is $900

Which table represents a linear functionWhich table represents a linear function
IceJOKER [234]

The table that has a constant average rate of change represents a linear function.

<h3>What is the average rate of change of a function?</h3>

The average rate of change of a function is given by the <u>change in the output of the function divided by the change in the input</u>.

When this rate is constant, the function is said to be linear, hence the table that has a constant average rate of change represents a linear function.
