Given the function f(x) = -5|x + 1 + 3, for what values of x is f(x) = -12?
omeli [17]
<h3>F(x) = - 5(x+1+3)</h3>

or, - 12= - 5x-5-15

or, - 12= - 5x-20

or, - 12+20= - 5x

or, 8= - 5x

or, x= 8÷-5

Also,

F(x)= - 5(x+1+3)

or, f(8÷-5)= - 5(8÷-5+1+3)

= - 5(8-5-15÷-5)

= - 5×-12÷-5

= - 12 #

Find the smallest possible interger value n for which 99n is a multiple of 24
motikmotik
I would guess that you would need to find the Least Common Multiple (LCM) of 99 and 24 first. 

After listing out all of the multiples, you would have 792 be the LCM of 99 and 24. But since we need to find the integer value of n, in 99n (which means 99 x n), then we need to divide 792 by 99, which would be 8.

n = 8

NISA [10]
First, let's write down this inequality:
<span>There are at least 245 students enrolled in the school.

 y≥245

This inequality says what the sentence says!

now, the number of teachers must be:
x≥2*(y/25)
 (two times the number of groups of students of 25!)

so those two inequalities, taken together will be the answer!
