When looking at a rational function f of x equals the quantity x plus three times the quantity x minus two times the quantity x plus five all divided by the quantity x minus three times the quantity x plus two times the quantity x minus 5 , Charles and Bobby have two different thoughts. Charles says that the function is defined at x = −2, x = 3, and x = 5. Bobby says that the function is undefined at those x values. Who is correct? Justify your reasoning.
Answers
Answer: Bobby is right, because at x = -2, 3, and 5, the denominator of the function equals zero, which is by definition undefined.

A straight line can be drawn through all of the the points but the line does not pass through the origin. A straight line can be drawn through all the points and the lines passes through the point where x = 0 and y = 0. A straight line can be drawn through all the points and the line passes through the point (3, 0). A straight line cannot be drawn through all the points and the line passes through the origin.
Answers
Answer:
a straight line can be drawn through all the points and the lines passes through the point where x = 0 and y = 0 (the origin).
Step-by-step explanation:
in a proportional relationship, one variable is always a constant value times the other. That constant "a" is know as the "constant of proportionality".
y = ax
and as you can easily see, that implies if x = 0, then y = 0.
therefore, the given answer is correct.

Answer: {-1, 0, 1}
Explanation: The range of a relation is the set of all y-coordinates.
So the range is {1, 0, -1} which would be your answer.
Note however that the range is usually written in ascending order.
In other words, from least to greatest.
So our range can be written as {-1, 0, 1}.

9 A wagon is accelerating down a hill at constant acceleration. It took is more to accelerate from a velocity
of I m/s to a velocity of 5 m/s than it took to accelerate from rest to a velocity of 1m/s. find the acceleration
Answers
Answer:
3 m/s²
Step-by-step explanation:
"It took 1 s more to accelerate from a velocity of 1 m/s to a velocity of 5 m/s than it took to accelerate from rest to a velocity of 1 m/s. Find the acceleration."
Acceleration is equal to change in velocity over change in time. The acceleration is constant, so we can write a proportion:
(1 m/s − 0 m/s) / t = (5 m/s − 1 m/s) / (t + 1 s)
1 / t = 4 / (t + 1)
4t = t + 1
3t = 1
t = ⅓
The acceleration is therefore:
a = Δv / Δt
a = (1 m/s − 0 m/s) / (⅓ s)
a = 3 m/s²

Answers
Step-by-step explanation:
Let people behind you=x
People ahead of you will be x+2
Total number of people in the line(including you) = x+(x+2)+1 = 2x+3
Also, 2x+3=3x
So x=3
People ahead = x+2 = 5
People behind = x = 3

A triangle always has 180° so that means 40° (2x+9)° and another angle add up to 180°.
We can find out two angles in order to find out the third, one of them is 40° the other is 180°-105° because there are 180° on a line.
you get 75.
75°+40°=115°
180°-115°=65°
2x+9=65°
Make x the subject of the formula:
2x=56
(take away 9)
x=28
(divide both sides by 2)

Jeff is decorating papers with the child he is babysitting. They have a total of 7 heart stickers and 14 star stickers to use. If they want to make all the papers identical with the same combination of heart and star stickers and no stickers left over what is the greatest number of pages they can decorate
Answers
Answer:
7
Step-by-step explanation:
Given the following :
7 heart stickers and 14 star stickers :
The greatest number of pages that can be decorated using the stickers above without any left over ;
To get this we obtain the greatest common factor of 7 and 14
Factors of 14
14 : 1, 2, 7, 14
Factors of 7
7 : 1, 7
The greatest factor common in both numbers is 7
Hence, greatest number of pages that can be decorated without any leftover is 7

For a function f(x), the difference quotient is 21x2 + 21xh + 7h2 + 2. Which statement describes how to determine the average rate of change of f(x) from x = –3 to x = 2? Substitute –3 for x and 2 for h in the difference quotient. Substitute –3 for x and 5 for h in the difference quotient. Substitute 2 for x and –3 for h in the difference quotient. Substitute 2 for x and –5 for h in the difference quotient.
Answers
Answer:
Substitute –3 for x and 5 for h in the difference quotient.
Step-by-step explanation:
The difference quotient for the function f(x) is 21x² + 21xh + 7h² + 2. Now, we know that the difference quotient equal f(x + h) - f(x) = 21x² + 21xh + 7h² + 2. The change in x is h = x₂ - x₁. So, if x changes from x = -3 to x = 2, where x₁ = -3 and x₂ = 2, h = x₂ - x₁ = 2 - (-3) = 2 + 3 = 5.
So to find the average rate of change of f(x) from x = -3 to x = 2, we substitute x = -3 and h = 5 into the difference equation f(x + h) - f(x) = 21x² + 21xh + 7h² + 2. Since, x starts at x = -3 and increases by 5 units to x = 2.
Answer:
(on edge) B. Substitute –3 for x and 5 for h in the difference quotient.

What is 3500/9 simplified?
Answers
Hey there!
Let's simplify
[tex]\bold{\displaystyle\frac{3500}{9} }}[/tex]
Is there any way we can simplify this fraction?
No. 3500 and 9 do not have any common factors.
This fraction is already in its simplest form.
However, [tex]\bold{\displaystyle\frac{3500}{9} }[/tex] is an improper fraction.
An improper fraction is a fraction where the numerator (top) is greater than its denominator.
You can easily remember where the denominator is by remembering this:
The Denominator is Down
The nice thing about improper fractions is that you can simplify them... A little.
Hey! How can we simplify a fraction that's already in its simplest form?!
If the fraction is improper, then we can just write it as a mixed number.
A mixed number is a number with both a whole number and a fraction.
Let's write this fraction as a mixed number.
First, how many times does 9 go into 3,500? (evenly)
388 times
Now, take 388 and multiply it times 9:
3,492
Subtract:
3,500-3,492=8
That's our numerator.
Therefore, the mixed fraction is
[tex]\bold{388\displaystyle\frac{8}{9} }[/tex]
We can easily check if this is correct by multiplying 388 times 9 and adding 8.
See? We ended up with 3,500.
Hence, 3500/9 simplified is
[tex]\boxed{\boxed{\bold{388\frac{8}{9} }}}[/tex]
Hope everything is clear.
