Using the concept of y-intercept, it is found that the response that is not correct is given by:
B) Replace x with -x.
<h3>What is the y-intercept of a function?</h3>
It is the value of the function when x = 0, hence it is the point (0, f(0)).
In this problem, the function is:

The y-intercept is given by:

If we just replace x with -x, we still have the same expression as above, hence the y-intercept does not change and option B is the answer to this question.

1615/170
We first need to convert this into a proper fraction. Which means that the denominator must be larger than the numerator for it to be proper. Also, since 1615 is BIGGER than 170, we will end up with a mixed fraction. A mixed fraction always has a whole number.
1615 can go into 170 how many times?
9 times
170*9 = 1530
Now subtract.
1615 - 1530 = 85
Now we have our mixed fraction: 9 85/170
Now we must simplify the fraction.
85/5 = 17
170/5 = 34
17/34 is the smallest possible fraction we can get.
9 17/34
Final answer:
Answer:
4x
Step-by-step explanation:
you just add the x
Answer:
It will take 5 weeks for you and your friend to have the same balance
Step-by-step explanation:
Let
Your savings expression be
135 + 12x
Your friends savings expression
95 + 20x
Where,
x = number of weeks for you and your friend to have the same balance
Equate the two expressions
135 + 12x = 95 + 20x
Collect like terms
135 - 95 = 20x - 12x
40 = 8x
Divide both sides by 8
40/8 = x
x = 40/8
= 5
x= 5 weeks
Check
Your savings expression
135 + 12x
135 + 12(5)
=135 + 60
= $195
Your friends savings expression
95 + 20x
95 + 20(5)
= 95 + 100
= $195
Therefore, It will take 5 weeks for you and your friend to have the same balance
The expectation of this game is that the house (casino) takes in roughly $3.83 every time someone plays, and after enough plays, they will typically always win.
We can determine this case by looking at all of the possibilities and how much you can win or lose off of each. There are 36 total cases for what can happen when we roll the dice. Of those 36 cases, 9 of them produce positive winnings and 27 of them produce losses.
To calculate the winnings, we need to look at what type they are. 6 of them will be 7's which earn the gambler $20. 3 of them would be 4's, which earns the gambler $40.
6($20) + 3($40)
$120 + $120
$240
Then we look at the losses. This is easier to calculate since every time the gambler loses, he losses exactly $14. There are 27 of these instances.
27($14)
$378
Now we can look at the average loss per game by subtracting the losses from the gains and finding the average.
(Winnings - losses)/options
($240 - 378)/36
$3.83
