What you need to know in order to answer this:
In math, the symbol " ! " is used to indicate "factorial".
"Factorial" means the product of the integers from 1
up to the number.
Examples:
2 ! = "two factorial" = 1 * 2 = 2
4 ! = "four factorial" = 1 * 2 * 3 * 4 = 24
For this question:
10 ! = "ten factorial" = 1 * 2 * 3 * 4 * 5 * 6 * 7 * 8 * 9 * 10
= 3,628,800 .
If you look at your calculator very closely, I'll bet you
there's a key on it marked " x ! " .
Enter a whole number into the calculator, and that key
gives you the factorial of the number.
And by the way, the points aren't 'free'. I had to
give you some information in order to earn them.
All you have to do is add exponents when multiplying like monomials. So it's just 4^2
Answer:
y = 
x + 1
Step-by-step explanation:
We have 8 - 5y = -2x
Rearranging gives;
5y = 2x + 8
Dividing through by 5 gives;
y = x + 
Simplifying gives;
y = x + 1
This is a standard linear equation form.
