get a common denominator of 20

3/5 * 4/4 =12/20

-1/4 * 5/5 = -5/20

7/10 *2/2 = 17/20

replace

Select the correct answer.

alex41 [277]

Answer:

Option B

Step-by-step explanation:

Average rate of change of a function 'f' in the interval x = a and x = b is given by,

Average rate of change of change = $\frac{f(b)-f(a)}{b-a}$

Given function is,

g(x) = $\frac{5}{x-1}+2$

We have to calculate the rate of change in the interval [-4, 3],

Average rate of change = $\frac{g(3)-g(-4)}{3-(-4)}$

g(3) = $\frac{5}{3-1}+1$

= 2.5 + 1

= 3.5

g(-4) = $\frac{5}{-4-1}+1$

= -1 + 1

= 0

Average rate of change = $\frac{3.5-0}{3+4}$

= $\frac{3.5}{7}$

= $\frac{1}{2}$

Therefore, Option B will be the answer.

Answer:

Simplification of an algebraic expression can be defined as the process of writing an expression in the most efficient and compact form without affecting the value of the original expression. The process entails collecting like terms, which implies adding or subtracting terms in an expression.
