Well....
A prime number is a number that can be divided by 1 or by itself, also having to be a whole number greater than 1. Ex. 5 can be divided by 1 or 5 so it is prime.
Hope this helps!
Answer:
Step-by-step explanation:
Rewrite this equation in standard quadratic form: x^2 + 13x + 4 = 0.
Here the coefficients are 1, 13 and 4, so the discriminant is
b^2-4ac, or 169 - 4(1)(4) = 153
Since the discriminant is + there are two real, unequal roots. They are:
-13 ± √153
x = ------------------
2
x = ----------------

Answer:
Step-by-step explanation:
So the sign means that y has to be less than or equal to x plus 9
if you wanted an answer an example could be
y = 1
x = 10
this works because if implemented into the equation
1 ≤ 10 + 9 which is true
