Answer:
(f o g)(-2)= 11
Step-by-step explanation:
Answer:
domain; x<0 or x>0
Step-by-step explanation:
We have been given the following function;
f(x) = 2x + 6/x^2 + 5x + 6
We need to evaluate the values of f(x) for the following domain values;
{-3, -2, 0, 2, 3}
f(-3) = 2(-3) + 6/(-3)^2 + 5(-3) + 6
= -43/3
f(-2) = 2(-2) + 6/(-2)^2 + 5(-2) + 6
= -6.5
f(0) = 2(0) + 6/(0)^2 + 5(0) + 6
= undefined
f(2) = 2(2) + 6/(2)^2 + 5(2) + 6
= 21.5
f(3) = 2(3) + 6/(3)^2 + 5(3) + 6
= 83/3
The function is real and defined for every value of x in its domain except where x = 0 . This is a point of discontinuity.
Find the attachment below;
Answer:
No, because the inequality symbol should be less than or equal to 650
Hi
3000+125x=2500+150x
500=25x
x=500/25
x=20
Therefore the answer will be 20 months.
All the best!
c = number of children
s = number of students
a = number of adults
since the theater has a capacity of 189, then c + s + a = 189.
there are half as many "a" as "c", so then a = c/2 or 2a = c.
so the cost for all children since the price for one is 5 bucks, the total will be 5*c or 5c.
likewise, the total cost for students is 7*s or 7s.
and for adults likewise is 12*a or 12a.
we know all ticket sales was 1372, so then 5c + 7s + 12a = 1372.
now, let's use the elimination method on that system of equations of two variables, let's multiply hmmmm say the first equation by -7, to eliminate the "s".
