Answer: The answer is 3 3/5 because you divide 2 1/4 and 5/8 you do KCF keep change flip but since it is a whole number divided by a fraction you multiply the whole number with the denominator and than add it by the numerator so no the problem is 9/4 • 8/5 which is 72/20 which is a improper fraction so it is 3 12/20 but it can be reduced to 3 3/5 and thats how you do it.
Answer:
f (g(x)) = 12x + 8
g(f(x)) = 12x + 48
Step-by-step explanation:
These are composition of functions.
(Unless I am reading your notation wrong) Are the functions multiplying eachother? Is the F actually a lower case f ?
Simply do some substitutions.
f (g(x)) = 2 ( 6x) + 8 = 12x + 8
g (f (x) ) = 6 (2x + 8) = 12x + 48

Answer:
Step-by-step explanation:
First let us determine the perpendicular line by remembering that a perpendicular line that intersects with the current line must have the opposite reciprocal slope as it. Meaning... the current slope is -1/2 and the opposite reciprocal is +2 or 2.
To clarify...
*opposite= the opposite sign ex. the opposite of +3 is -3 and the opposite of -1 is +1
*reciprocal=put simply, the reciprocal is the flipped version of the current number ex. the reciprocal of 1/2 is 2/1 or 2 and the reciprocal of 3 or 3/1 is 1/3
After we determine the slope of the perpendicular line, we are also know the point it must pass through.
Given that, we can find the equation.
Using y=mx+b
Plug in known varibles
y=-5
x=-4
m=2
b=?
-5=2(-4)+b
b=3
So now that we have b, we can put the equation in standard form.
y=2x+3
Hope this helps!!!
