Hello,

In order to be simple: let's code hexadecimal numbers on 4 digits.

Example: 500-200=300 (in décimal)

500_{10}=01F4_{16}\\\\
200_{10}=00C8_{16}\\\\
For\ subtract\ 00C8\ we\ calculate\ 15th\ complement\\\\
C_{15}(00C8)=FF37\\\\

16th\ complement= FF37+0001=FF38\\\\

Then\ we\ add\\\\

01F4+FF38=(1)012C\ on\4\ digits:\ 012C\\

012C_{16}=300_{16}

A new car is purchased for $47, 000 and over time its value depreciates by one half
andrey2020 [161]

Answer:

$1500

Step-by-step explanation:

you can figure it out by going in increments of 4.5 years because that is the info you have from the problem so

47000 4.5 years later is 23500

9 years = 11750

13.5y = 5875

18y = 2937.5

22.5 years later is 1468.75

22.5 years is about 23 years and to the nearest hundred dollars that is $1500 so that is the answer

Hope this helps! :)

Write the equation of a line through points (5, 5) and (1, 0) in point-slope form
klasskru [66]

Answer:

y=(5/4)x-5/4

Step-by-step explanation:

First we need to find the slope:

\frac{y_{2}-y_{1} }{x_{2}-x_{1} }

=\frac{5-0}{5-1}

=5/4

The SLops is 5/4

point-slope forum is

y=(5/4)x-5/4

(i think)

Solve equation <br> √ 13x+27=√ 4x
natima [27]
What you have to do is rearrange the equation by subtracting what is on the right of the equal sign from both sides of the equation 

so it would be 4*x-13*x-(27)=0
