Let f(x)=9x-2 and g(x)=-x+3. find f(g(x)).

Answers

$f(g(x))=9(-x+3)-2 \n f(g(x))= -9x+27-2 \n f(g(x))= -9x+25$

$f(x)=9x-2;\ g(x)=-x+3\n\nf(g(x))=9(-x+3)-2=-9x+27-2=-9x+25$

What is the solution of the equation below?x/6=x-4/2

Answers

x / 6 = -4 / 2
x / 6 = -12 / 6
x = -12 :)

we do it by cross multiplication.

x/6 = x-4/2

2x = 6x-24

2x-6x = -24

-4x = -24

thus, x = -24/-4

thus, x = 6.

Jane arranges m chairs in each of n rows to seat x people.The formula to find the number of chairs in each row is m =
_____________________
If 60 people attend the meeting and each row has 4 chairs, there are _______________________________________
rows.

Answers

The formula to find the number of chairs in each row is m = x ÷ n,
where
m - the number of chairs,
n - the number of rows,
x - the number of people.

If 60 people attend the meeting and each row has 4 chairs, there are 15 rows.
This is assumed using the above formula:
m = x ÷ n

If:
x = 60
m = 4

Then:
4 = 60 ÷ n
⇒ n = 60 ÷ 4
⇒ n = 15
