Answer:
c. 3 1/3
Step-by-step explanation:
8x-2-5x=8
3x=10
x=10/3=3 1/3
The difference of course is the symbol between the f and g letters.
The circle notation means we're doing a function composition.
Writing is the same as saying where g is the inner function.
Here's an example
f(x) = x^2
g(x) = 3x
f( g(x) ) = ( g(x) )^2 ... note how x is replaced with g(x)
f( g(x) ) = ( 3x )^2
f( g(x) ) = 9x^2
-------------------
On the other hand, the dot notation means we multiply the f(x) and g(x) functions.
Going back to the previous example, we could say

Answer:
Step-by-step explanation:
The four walls have a linear length of (9 m)×4 = 36 m. Of that, the two 1-meter doors are not painted, so the linear length of the painted area is 34 m. The painted area is 2 m high, so the total area being painted is ...
A = LW
A = (34 m)(2 m) = 68 m²
The amount of paint needed for this area is ...
(68 m²) × (1 L/(10 m²) = 6.8 L
If we assume the paint only comes in units of 1 L, then Heather will need 7 L of paint.
The cost of 7 L of paint is ...
(7 L) × ($3.75/L) = $26.25
Heather will need 7 L of paint, for a total cost of $26.25.
