Answer:
Step-by-step explanation:
First, turn the word problem into an equation:
n(a number) was divided by 2
followed by this quotient beying multiplied by 4
*4
the product was added to 9
*4+9
the total sum was 25
*4+9 = 25
use PEMDAS to solve the equation
subtract 9 on both sides
*4 = 16
cancel the 2 and the 4 using factorization
n*2 = 16
divide 2 on both sides
n = 8
Answer:
A <5
Step-by-step explanation:
You simplify both sides of the inequality, then isolate the variable.
Answer:
2 real roots
Step-by-step explanation:
If the discriminant is any positive number, that means the quadratic will have 2 real roots, or solutions.
Since the discriminant, 36, is a positive number, this will apply.
So, if the discriminant is 36, there will be 2 real roots.
Answer:
No correlation
Step-by-step explanation:
There is not a positive line of dots
There is not a negative line of dots
so that means there is no correlation
Its 100 because its not rounded to the nearest whole like 200 because its less than 50 so it would round down
