The lease common denominator using prime factorization would be 2. 2 is the number they can both be divided by and is also a prime number
4m + 7 = -3m + 49
4m + 3m = 49 - 7
7m = 42
m = 42/7
m = 6
So, your final answer is 6
Hope this helps!
To find the mean add up all the numbers given then divide your answer by how many numbers there are.
for ex: 1,2,3,4,5
1+2+3+4+5= 15
15 divided by 5 = 3
so the mean is 3
Answer:
hf(x) = 3/(x² - 1)
fh(x) = (9 - x²)/x²
Step-by-step explanation:
h(x) = 3/x
f(x) = x² - 1
h(f(x)) = 3/f(x)
hf(x) = 3/(x² - 1)
f(h(x)) = (h(x))² - 1
= (3/x)² - 1
= 9/x² - 1
fh(x) = (9 - x²)/x²
