Answer:

-434

Step-by-step explanation:

If f(a) = 4 then,

f(4) = 4⁴ - 3(4)³ - 8(4)³ + 19(4) - 22

4⁴ - 3(4)³ - 8(4)³ + 19(4) - 22

256 - 3(64) - 8(64) + 19(4) - 22

256 - 192 - 512 + 76 - 22

64 - 512 + 76 - 22

-488 + 76 - 22

-412 - 22

= -434

Which expression is equivalent to the following complex fraction?
Sedbober [7]

Answer: the second option is the correct answer

Step-by-step explanation:

The given expression is

[3/(x - 1) - 4]/[2 - 2/(x - 1)

We would simplify the numerator first. The LCM of the numerator is

x - 1. Taking the LCM of the numerator, it becomes

[3 - 4(x - 1)]/(x - 1)

= [3 - 4x + 4]/(x - 1)

= (- 4x + 7)/(x - 1)

We would simplify the denominator. The LCM of the denominator is

x - 1. Taking the LCM of the numerator, it becomes

[2(x - 1) - 2]/(x - 1)

= [2x - 2 - 2]/(x - 1)

= (2x - 4)/(x - 1)

= 2(x - 2)/(x - 1)

The expression becomes

[(- 4x + 7)/(x - 1)]/[ 2(x - 2)/(x - 1)]

= (- 4x + 7)/(x - 1) × (x - 1)/2(x - 2)

(x - 1) cancels out. It becomes

(- 4x + 7) / 2(x - 2)
