Answer:
Her next step would be to add 12 to both sides of the equation
Step-by-step explanation:
Which would make the equation 4x=28
Then you divide both sides by 4 giving you x=7
Answer:
The Domain is all real values of x except x = 0 and x = -2.5.
Step-by-step explanation:
I am assuming that f(x) = 3/(x + 2).
(f o g)x is found by substituting 5/x for the x in 3/(x + 2).
(f o g) x = 3/ ( 5/x + 2)
= 3 / ( 5+2x) / x
= 3x / (5 + 2x).
When finding the domain you first check for values of x which make g(x) undefined then values of x which make (f o g)(x) undefined.
x = 0 makes g(x) = 5/0 so it is undefined and x = -2.5 makes g o f undefined also.
Each number is multiplied by 3. 3x3=9, 9x3=27, and so forth. the answer is logically 243
56÷2=28
28-1=27
so the smaller number is 27
$ 1 U.S. dollar = 0.76 euros
so $ 30 U.S. dollars = (30 * 0.76) = 22.8 euros <==
