Answer:
Since f(x) is a first order equation, it has only one zero
f(x) = -20*x +23*x -6
This means that
f(x) = (-20 + 23)*x -6
f(x) = (3)*x -6
If we mame the previous equation equal to zero ----->
(3)*x -6 = 0
x = 2
which means, the factorization is equal to
(x-2) = 0
f(x) = 3*(x-2)
Given that the raffle prize is to be divided equally, the amount of money each person will receive will be equal to the total raffle prize (14x^(2)/15) divided by the number of people (7x). Thus, we get:
(14x^(2)/15) / 7x
= (14x^(2)/15) * (1/7x)
= 14x^(2)/15*7x
= 14x^(2)/105x
= 2x/15 (Divide both the numerator and denominator by 7x)
Therefor, each person would receive 2x/15 dollars.
If you know how to cancel when dealing with fractions, you can get to this step much easier, however this way also works. The idea with cancelling would be that when you had (14x^(2)/15) / 7x, you would recognise that 14x^2 may be divided by 7x straight away to get 2x. Then you would have 2x/15 as your answer.

Answer: $350 because you multiply 140 and 100 then divide 40
Answer:
x = 31
Step-by-step explanation:
For the sum of the saved amounts to be 286, we must have ...
(5x +4) +(4x +3) = 286
9x = 279 . . . . . . . . . . . . . subtract 7
x = 31 . . . . . . . . . . . . divide by 9
The value of x would be 31.
