Part A: Yes, the data represent a function. The definition of a function is a relation in which no value of x will have two different values of y.
(Every time you plug in 3 as x, you will always get 4 as y; it's ok if you plug in 3 and 5 as x and get the same y, you just can't get two different y's for one x; sorry, it is pretty confusing). None of the numbers in the table repeat, so we can safely say that the relation is a function.
Part B: All we have to do is plug in 11 for x in the function given to find the answer:
In the table, y = 8 when x = 11, but in the function given, y = 34 when x = 11, so the function given is greater.
Part C: To find the answer to C, just plug in 99 for f(x), as it tells you to do:
Divide 3x2 − 11x − 4 by x − 4.
Answer:
3x+1
Step-by-step explanation:
Answer: 3x + 1
Step-by-step explanation:
Convert the numerator in factored form
Group terms that contain the same variable, and move the constant to the opposite side of the equation
Factor the leading coefficient
Complete the square. Remember to balance the equation by adding the same constants to each side.
Rewrite as perfect squares
Square root both sides
therefore you must

You are going to have a quiz with 5 true/false questions next Friday. You
want to find the probability of passing the quiz, if you guess on each
question.
Create a simulation that would represent this situation and complete 10
trials. Show all of your work for full credit.
Based on the binomial probability principle, the probability of passing the quiz if all answers are guessed [tex] P(x = k) = 10Ck \times 0.50^{k} \times 0.50^{10-k} [/tex]
Let :
Number of questions passed = kNumber of trials, n = 10Probability of success, p = 1/2 = 0.50q = 1 - p = 1 - 0.50 = 0.50Using the binomial probability relation :
[tex] P(x = x) = nCx \times p^{x} \times q^{n-x} [/tex] x = kSubstituting the values into the relation :
[tex] P(x = k) = 10Ck \times 0.50^{k} \times 0.50^{10-k} [/tex]
Hence, the required probability expression is [tex] P(x = k) = 10Ck \times 0.50^{k} \times 0.50^{10-k} [/tex]

Which expression is equivalent to the expression shown below?
20 + 8y - 9y - 21
Select each correct answer.
2(10 + 4y - 7y - 19)
2(10 + 4y) - 3(3y - 7)
4(5 + 2y - 5y - 17)
4(5 + 2y) - 3(3y + 7)
-(y + 1)
-(1 - y)
y - 1
Answer:
4(5+2y)=3(3y+7) and -(y+1)
Step-by-step explanation:
You combine like terms
20-21 =-1
8y -9y = -1y
so your answer is anything that is the same as -1 - y
2(10+4y-7y-19) =2( -3y-9) = -6y-18 NO
2(10 +4y) - 3(3y-7) = 20 +8y - 9y +21 = -y +41 NO
4(5+2y-5y-17)= 4(-3y -12) = -12y -48 NO
4(5+2y) - 3(3y+7) = 20 +8y - 9y -21 = -1 = y YES
-(y+1)= -y-1 YES
-(1-y) = -1+y NO

Step-by-step explanation:
5(w-2)=-2(1.5w+5)
5w-10=-3w-10
8w=0
w=O
Answer:
W=0
Step-by-step explanation:
5(w-2)=-2(1.5w+5)
5w-10= -3w-10
5w+3w=-10+10
8w=0
W=0
So the value of w is 0
Mia and her children went into a grocery store and where they sell apples for $2 each and mangos for $1.50 each. Mia has $20 to spend and must buy no less than 9 apples and mangos altogether. If Mia decided to buy 3 mangos, determine the maximum number of apples that she could buy. If there are no possible solutions, submit an empty answer.
Answer:
The maximum amount of apples she could buy is 7
Step-by-step explanation:
3 mangos would be 4.50 dollars. Subtract that from her current amount of money (20 dollars). You would get 15.5 dollars. Then, find how many apples she can buy with 15.5 dollars. You can't buy 8 because that would be above 15.5. So do the next smallest amount, 7.

Question 1(Multiple Choice Worth 5 points)
(04.06A HC)
The table and the graph below each show a different relationship between the same two variables, x and y:
A table with two columns and 5 rows is shown. The column head for the left column is x, and the column head for the right column is y. The row entries in the table are 3,180 and 4,240 and 5,300 and 6,360. On the right of this table is a graph. The x axis values are from 0 to 10 in increments of 2 for each grid line. The y axis values on the graph are from 0 to 350 in increments of 70 for each grid line. A line passing through the ordered pairs 2, 70 and 4, 140 and 6, 210 and 8, 280 is drawn.
How much more would the value of y be in the table than its value on the graph when x = 11?

Answer:
y= 4x -5 x^-1
Step-by-step explanation:
xy'+y=8x
y' + y/x =8
linear DE
integrating factor = e^∫1/x dx = x
y = 1/x ( ∫8x dx +C)
y= 1/x (4x^2 +C)
y= 4x + C x^-1
C is any constant.. in this case -5 is satisfying equation
Let f be a function such that f(2) ≤ f(x) for all values of x in the interval (0, 3). Does f(2) represent a relative minimum or a relative maximum?
Answer: f(2) is a relative minimum
This is because f(2) is the lowest y output for any given y = f(x) output on the interval [tex]0 < x < 3[/tex] which is what the interval notation (0,3) indicates.
Draw out a "parabolic" like shape where the lowest point occurs at (2, f(2)), where f(2) is unknown, but we at least know that x = 2. I put "parabolic" in quotes because it may not be a true parabola, but it looks like one. This lowest point only applies for the neighbor hood [tex]0 < x < 3[/tex].

Before multiplying fractions change any mixed numbers to
[A] decimals
[B] estimated numbers
[C] percent
[D] improper fractions
9514 1404 393
Answer:
[D] improper fractions
Step-by-step explanation:
The usual recommendation for doing much of anything with mixed numbers is to change them to improper fractions.
__
However, that isn't always necessary. If you're doing the arithmetic with a calculator, it can be helpful to convert them to decimal numbers.* Sometimes, you can work with mixed numbers by working with the integer and fractional parts separately.
Sometimes a simple rewrite makes working with mixed numbers easier. (That is, converting part of the integer portion to a fraction may be useful in some cases.
Example:
(29 1/3) × (1/2) = (28 4/3) × (1/2) = 14 2/3
_____
* Some calculators will do arithmetic directly with mixed numbers and/or fractions. If yours doesn't, it can be helpful to memorize the decimal equivalents of a few common fractions: 1/3, 2/3, 1/6, 1/7, 1/9, 1/11 for example. This will help you convert the decimal result back to a mixed number.
