Determine whether the relation represents a function.
O Yes, It is a function.
No, it is NOT a function.
Answer:
No, it's not function
Step-by-step explanation:
Every function is a relation but every relation is not a function because:
Function: a special type of relation in which the first-order pairs are different.
In this case {(-3,-4), ......., (-3,5)} these two sets have the same first-order pair.
So, your answer will be 'It's not function.'.

A. 4 > x > 7
B. 4 < x < 7
C. −2 > x > 1
D. −2 < x < 1
Please explain why you have gotten the right answer!

so it's b the correct option
Answer:
D. -2 < x < 1
Step-by-step explanation:
1 < x + 3 < 4
=
{1 < x + 3
{x + 3 < 4
=
{ 1 + ( -3 ) < ( x + 3 ) + ( -3 )
{ ( x + 3 ) + ( -3 ) < 4 + ( -3 )
=
{ 1 - 3 < x + 3 - 3
{ x + 3 - 3 < 4 - 3
=
{ -2 < x
{ x < 1
=
{ x > - 2
{ x < 1
Hence, the answer would be : -2 < x < 1

In the given question, it is stated that Isabella bought a total of 84 Tickets. Each of the tickets she bought cost $16.22. We have to find out the total amount that she spent on buying tickets for everyone. From this given situation we know:
The cost of one ticket: $16.22
Total number of tickets: 84
From this formula, we can calculate the total amount spent
Total Amount = Total ticket * cost of one ticket
Putting values in this formula, we get:
=> Amount = cost*number
=> Amount = 16.22*84
=> Amount = 1362.48
Hence, the Total amount that she spent on Tickets will be $1362.48

Answer: F. $1.25
Explanation:
First, we need to find the probability of the coin landing faceup and facedown. We know that landing faceup is 3 times the probability of landing facedown. Since the highest probability is 1 (100%):
[tex]\begin{gathered} 3x+x=1 \\ 4x=1 \\ x=\frac{1}{4}=0.25 \end{gathered}[/tex]With this, we know that:
probability of the coin landing faceup = 3×0.25 = 0.75
probability of the coin landing facedown = 0.25
To find the expected value of each toss, we need to solve for the total of each value multiplied by its probability:
[tex]\begin{gathered} EV=\$1(0.75)+\$2(0.25) \\ EV=\$1.25 \end{gathered}[/tex]Therefore, the expected value of each toss of Coin C is $1.25

Answer:
(2) The 3 was not distributed correctly.
3(x + 4) is the same as 3(x) + 3(4) Which is 3x + 12 not 3x + 4
Step-by-step explanation:
Answer: The error was at the first step since 4 was never multiplied by 3, therefore the final answer would be incorrect.
Step-by-step explanation: 3(x + 4) = 13
multiply 3 by everything in the parenthesis, so
3x + 12 = 13
subtract 12 from each side.
3x = 1
divide both sides by 3

If the value of a lies in between - 1 and 1 in the absolute value function y = a|x|, then the graph is farther from the ______________.y = -xy = xy-axisx-axis
SOLUTION:
If the value of a lies in between - 1 and 1 in the absolute value function y = a|x|, then the graph is farther from the y- axis. This is because the bounding lines of the function are the lines y = x and y = -x. Thus, when a varies from -1 to 1, the graph gets farther from the y-axis.

Determine g(x−1) for the following function. g(x)=−4x−1
The function operation g( x - 1 ) of the function g( x ) = −4x − 1 is -4x + 3.
What is the function operation g( x - 1 ) in the given function?A function is simply a relationship that maps one input to one output.
Given the data in the question;
g( x ) = −4x − 1g( x - 1 ) = ?To find g( x - 1 ), replace all the occurrence of x with ( x - 1 ) in the function and simplify.
g( x ) = −4x − 1
g( x - 1 ) = −4( x - 1 ) − 1
Simplify by distributive property
g( x - 1 ) = −4( x - 1 ) − 1
g( x - 1 ) = x( -4 ) - 1( -4 ) - 1
g( x - 1 ) = -4x + 4 - 1
g( x - 1 ) = -4x + 4 - 1
Add 4 and -1
g( x - 1 ) = -4x + 3
Therefore, the function operation g( x - 1 ) is -4x + 3.

GH has a midpoint at M(-4.5, 5.5). Point G is at
(-10, 14). Find the coordinates of point H.
Answer:
(-1, 3)
Step-by-step explanation:
We could imagine the point G and H are points on a straight line.
We know that:
Point G is at (-10, 14)
Midpoint at M (-4.5, 5.5)
To calculate the x coordinate of the mid-point, we suppose to subtract x coordinate of H from coordinate x of G, divide by 2 to get the x coordinate of the midpoint m, which is -4.5
To calculate the y coordinate of the mid-point, we suppose to subtract y coordinate of H from y coordinate of G, divide by 2 to get the x coordinate of the midpoint m, which is 5.5
Therefore, x coordinate of H:
(- 10 - x) / 2 = -4.5
-10 - x = -9
- x = 1
x = - 1
And y coordinate of H:
(14 - y) / 2 = 5.5
14 - y = 11
- y = -3
y = 3

[tex]\begin{gathered} 6=30\cdot(\frac{1}{2})^{\frac{t}{36}} \\ \frac{6}{30}=(\frac{1}{2})^{\frac{t}{36}} \\ \frac{1}{5}=(\frac{1}{2})^{\frac{t}{36}} \\ \frac{t}{36}\ln (\frac{1}{2})=\ln (\frac{1}{5}) \\ t=\frac{36\ln\left(5\right)}{\ln\left(2\right)} \\ t=83.589 \\ t\approx84 \end{gathered}[/tex]Finally we obtain that after approximately 84 hours the valium concentration will reach 20% of it's initial level.
Find the volume of a cone with a base diameter of 6 yd and a height of 8 yd.Use the value 3.14 for 1, and do not do any rounding.Be sure to include the correct unit in your answer.
ANSWER
[tex]\begin{equation*} 75.36\text{ }yd^3 \end{equation*}[/tex]EXPLANATION
The volume of a cone is given by:
[tex]V=\frac{1}{3}\pi r^2h[/tex]where r = radius of the base of the cone
h = height of the cone
The diameter of the base of the cone is twice the radius. This implies that the radius of the cone is:
[tex]\begin{gathered} D=2r \\ r=\frac{D}{2} \\ r=\frac{6}{2} \\ r=3\text{ }yd \end{gathered}[/tex]Hence, the volume of the cone is:

The linear parent function, f(x) = x, transformed to g(x) = x+ 7. Whichstatement correctly compares the graphs of the functions?A. The graph of g(x) is less steep than the graph of f(x) and theyintercept has been shifted down.B. The graph of g(x) is steeper than the graph of f(x) and theyintercept has been shifted up.C. The graph of g(x) is less steep than the graph of f(x) and theyintercept has been shifted up.D. The graph of g(x) is steeper than the graph of f(x) and theyintercept has been shifted down.
The parent function given is
[tex]\begin{gathered} f(x)=x \\ \text{its has a slope of 1} \end{gathered}[/tex]The transformed function given is
[tex]\begin{gathered} g(x)=\frac{1}{2}x+7 \\ \text{which has a slope of 1/2} \end{gathered}[/tex]There is a reduction in the slope of the functions which makes the transformed function become less steep
The slope reduced from
[tex]1\text{ to 1/2}[/tex]There is also a change in the intercept from
[tex]0\text{ to +7}[/tex]And this indicates that the transformed function has been shifted up by 7 units
With the explanation above, we can therefore conclude that the statement which compares the two graphs of the function is
The graph of g(x) is less steep than the graph of f(x) and the intercept has been shifted up
Hence, The correct answer is OPTION C
