Find the least common denominator of 7/20 and 3/28
Genrish500 [490]

Answer:

140

Step-by-step explanation:

We have been given two fractions \frac{7}{20} and \frac{3}{28}. We are asked to find the least common denominator of both fractions.

To find the least common denominator of both fractions, we will find least common multiple of 20 and 28.

Prime factorization of 20: 2\times 2\times 5

Prime factorization of 28: 2\times 2\times 7

Least common multiple of 20 and 28 would be: 2\times 2\times 7\times 5=140.

Therefore, the least common denominator of both fractions would be 140.

Given the functions f(x)= 1/x−4 +3 and g(x)=1/x+1 +6 .
melomori [17]

ANSWER

The graph shifts 5 units left and 3 units up.

EXPLANATION

The given functions are:

f(x) =  \frac{1}{x - 4}  + 3

and

g(x) =  \frac{1}{x + 1}  + 6

We want to transform f(x) so that, it coincide with the g(x).

The required transformation is

f(x+5)+3

Let us see why this works.

f(x+5)+3 = \frac{1}{x + 5- 4}  + 3 + 3

f(x+5)+3 = \frac{1}{x + 1}  + 6 = g(x)

The transformation f(x+5)+3 will shift f(x) 5 units left and 3 units up.

The third choice is correct.
