Answer:
x = -1.4
Step-by-step explanation:
Subtract the right side and simplify.
5 - 6(2 - x) - (x - 14) = 0
5 - 12 + 6x - x + 14 = 0 . . . . parentheses eliminated
7 + 5x = 0 . . . . . . . . . . . . . . terms collected
1.4 + x = 0 . . . . . . . . . . . . . . divide by 5
x = -1.4 . . . . . . . . . . . . . . . . . add the opposite of the constant
_____
Check
5 -6(2 -(-1.4)) = (-1.4) -14
5 - 6(3.4) = -15.4
5 -20.4 = -15.4 . . . . . true. Answer checks OK.
In the question "Marta’s mother shared a funny video of their cat on the Internet. The total number of people who had viewed the video over the first 30 days could be modeled using the function f(x) = 33(1.3)x where x is the number of days the video has been online.
About how many people had viewed the video once it had been online for 20 days?" The correct answer is 6271 because given the function f(x) = 33(1.3)^x where x is the number of days the video has been online.
For x = 20 days: f(20) = 33(1.3)^20 = 33(190.0496377) = <span>6,271</span>
The additive inverse of a number a is the number that's added to yields zero
