Step-by-step explanation:

You can insert different values of x to find y

For example:

x = 4

Plug in x into the equation

y = -1/2(4) + 5

y = -2 + 5

y = 3

So your point will be (4, 3)

If you do 1 more like this, you can draw a line between them. Or you can use Desmos to graph the line.

Hope this helped you!!

Emily needs to hire a pilot. Pilot A is offering his services for an initial $32 in addition to $22.18 per hour.

Verizon [17]

Answer:

After working for 3. 74 hours, BOTH pilots will charge same amount.

Step-by-step explanation:

Let us assume in m hours, BOTH PILOT charge the same amount of money.

About PILOT A:

The fixed rate = $32

The rate per hour = $22.18

So, if the pilot A works for m hours, then :

Charge for m hours = m x (charge per hour) = m x ($22.18) = 22.18 m

So, the Total cost for hiring Pilot A = Fixed charge + Cost for m hour

Total cost for hiring Pilot A = $32 + 22.18 m .......... (1)

About PILOT B:

The fixed rate =$46.75

The rate per hour = $18.24

So, if the pilot B works for m hours, then :

Charge for m hours = m x (charge per hour) = m x ($18.24) = 18.24 m

So, the Total cost for hiring Pilot B = Fixed charge + Cost for m hour

Total cost for hiring Pilot B = $46.75 + 18.24 m .......... (2)

Now,as for m hours, they charge the SAME:

⇒ From (1) and (2)

$32 + 22.18 m = $46.75 + 18.24 m

or, 3.94 m = 14.75

or m = 14.75/3.94 = 3.74

or, m = 3.74 hours

Hence, after working for 3. 74 hours, BOTH pilots will charge same amount.

Use each model to predict the life expectancy of residents of a country for which the average annual income is $80,000

Mandarinka [93]

The life expectancies of residents of a country for which the average annual income is $80,000 for the three models are 12309.9352, 172.2436 and 4828.1393

The life expectancies of the models are given as:

$y =69.9352 + 0.1530\times (income)$ --- model 1

$y =4.2436 + 0.0021\times (income)$ --- model 2

$y =4.1393 + 0.0603\times (income)$ --- model 3

Given that the average annual income is $80,000;

We simply substitute 80000 for income in the equations of the three models.

So, we have:

Model 1

$y =69.9352 + 0.1530\times (income)$

$y =69.9352 + 0.1530\times 80000$

$y =12309.9352$

Model 2

$y =4.2436 + 0.0021\times (income)$

$y =4.2436 + 0.0021\times 80000$

$y =172.2436$

Model 3

$y =4.1393 + 0.0603\times (income)$

$y =4.1393 + 0.0603\times 80000$

$y =4828.1393$

Hence, the life expectancies are 12309.9352, 172.2436 and 4828.1393
