Answer:

y =  8 \:  \:  \: x =  - 10

Step-by-step explanation:

4( - 6x - 9y =  - 12) \\ 3(8x + 9y =  - 8) \\  \:  \:  \:  \:  \:  \:  \\  - 24x - 36y =  - 48 \\ 24x + 27y =  - 24 \\  \\  - 9y =  - 72 \\ y = 8 \\  \\  \\  \\  \\  - 6x  -  9y=  - 12 \\  - 6x  -  72 = -  12 \\  - 6x =  - 12 + 72 \\  - 6x = 60 \\ x =  - 10

When hired at a new job selling electronics, you are given two pay options: • Option A: Base salary of $10,000 a year with a com
MArishka [77]

Using linear functions, it is found that the number of electronics that you need to sell for a larger income in option A is x > 200,000.

<h3>What is a linear function?</h3>

A linear function is modeled by:

y = mx + b

In which:

  • m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
  • b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

Considering the <u>base salaries as the intercept and the commissions as the slope</u>, the functions are given by:

  • A(x) = 10000 + 0.09x.
  • B(x) = 20000 + 0.04x.

To produce a larger income in option A, it is needed that:

A(x) > B(x).

Hence:

10000 + 0.09x > 20000 + 0.04x

0.05x > 10000

x > 10000/0.05

x > 200,000

Chad drove 168 miles in 3 hours. How many miles per hour did Chad drive?
igor_vitrenko [27]


°° Let's see -

Basically, you divide the number of miles Chad drove by the number of hours it took. Then, it gives you the number of miles Chad drove in one hour. Let's try it!

168 ÷ 3 = 56

You can now see that Chad drove 56 miles in one hour.
