For this case we have the following polynomial:

Rewriting the polynomial we have:

From here, we can solve the polynomial using the quadratic equation
We have then:





Therefore, the solutions are:


I took 400 - 150 divided by 15 and got 16. So believe that should could afford to bring 16 people.
N/4 < -1 — we can multiply both sides with 4, so we dont have to deal with fractions.
N < -4
So, our N goes left from -4 on a number line.
-10x<-100 — divide both sides by 10
-x < -10
x > 10
X is from 10 rightwards.
5x>20 — divide both sides by 5
x > 4
X is rightwards from 4.
Answer:
The Base-10 system.
Step-by-step explanation:
our everyday number system is a Base-10 system. • the Base-10 number system is known as the decimal system. and has 10 digits to show all numbers. 0,1,2,3,4,5,6,7,8,9. using place value and a decimal point to separate.
