Answer:
84dgree÷3hours=26 degrees/ hour
With rounding:

is less than

so we round it down to whole number:


is more than

so we round it up to whole number:

Now we have to add rounded numbers

Without rounding:

to make it more visible I will write it differently:

is equal to

we can see that

is equal to

so:

<span>As you see in this example those equations are equal so it doesn't matter if you take rounded numbers or not, it may be different in case like

(

is just an example it could be any other number between

) because in this case it will be equal

and another example

(in this case

is just an example, it can be any other number between

:) ) and here, answer for this equation is

Answer:

Step-by-step explanation:
because it's has two zeroes
hence it is known as the quadratic function
The solution for X when y= 0 is x=10,-10 because you substitute 0 for y> 0=x^2-100 then its going to be 100=x^2 so you'll get x=10 or x=-10
Given:
Cost of a game = $39.99
Shipping charge = $4.85
Let,
number of video games be "n"
Now,
total cost = (cost of each game * total no. of games) + shipping charge
= $39.99n + $4.85
So, you use the above equation to find the total cost of video games.
