Answer:
#2 is not a function
Step-by-step explanation:
Although there can be multiple y-values attributed to a single x-value, there can only be ONE x-value(of a number) in a function, so #2 would be incorrect seeing as it uses the x-value, 2, two times.

Answers
Answer: 45
Step-by-step explanation:
Set up a number line with 1 60 and 100. To get from 100 to 1 you divide by 100 so you also do that to 60 then to get 1 to 75 multiply by 75 same with 0.6 which will be 45

At time x=0, water begins to drip steadily out of a water tank. After 3 hours , there are 6.8 gallons of water in the tank. After 9 hours, 4.4 gallons remain. Write a linear function rule that models the number of gallons of water y left in the tank for any number of hours x. The linear function rule is y = ___
Answers
Answer:
[tex]y=-0.4x+8[/tex]
Step-by-step explanation:
Let the Linear Function to represent the drip of water out of the water tank be:
[tex]y=mx+c[/tex]
Where [tex]x[/tex] is the time
[tex]y[/tex] is the number of gallons at that time
[tex]m[/tex] is the rate at which water drips
[tex]c[/tex] is the initial number of gallons of water in the tank
Putting the given values in the above equation:
[tex]6.8 = m\times 3+c ..... (1)[/tex]
[tex]4.4 =m\times 9+c..... (2)[/tex]
Subtracting (1) from (2):
[tex]6m=-2.4\\\Rightarrow m =-0.4[/tex]
Putting in equation (1):
[tex]6.8=-0.4\times 3+c\\\Rightarrow c = 8[/tex]
Therefore, the linear function equation to represent in the situation is:
[tex]y=-0.4x+8[/tex]
Michael started a savings account with $300. After 4 weeks, he had $350 dollars and after 9 weeks, he had
$412.50. What is the rate of change of money in his savings account per week?
Answers
Answer: 12.5
Step-by-step explanation:
He made 50 dollars in 4 weeks so divide that equally amongst each week you get 12.5
The rate of change of money in his savings account per week is 12.5
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
We have, After 4 weeks, he had $350 dollars and after 9 weeks, he had
$412.50.
So, We can consider it as (4, 350) and (9, 412.5)
So, the rate of change is
=(412.5-350)/ (9-4)
= 62.5
= 12.5
Hence, the rate of change is 12.5.

Movie Mania requires customers to pay a sign-up fee of $20, and charges $4.00 to rent a DVD. Hurricane Video is free to join, but DVDs cost $6.00 to rent. Write and solve an equation to find the number of DVDs you would have to rent in order for both stores to charge the same. Explain what your variable represents. A. Let n = the cost of renting a movie; 20n + 4 = 6; 40 videos B. Let n = the number of DVDs rented; 20 + 4n = 6n; 10 videos C. Let n = the cost of renting a movie; 20n + 4 = 6; 2 videos D. Let n = the number of DVDs rented; 20 + 4n = 6n; 40 videos
Answers
Answer:
B. Let n = the number of DVDs rented; 20 + 4n = 6n; 10 videos
Step-by-step explanation:
Let n = number of DVDs to rent
Movie Mania = 20 + 4n
Hurricane = 6n
Equate the cost of renting a DVD in both stores
Movie Mania = Hurricane
20 + 4n = 6n
20 = 6n - 4n
20 = 2n
Divide both sides by 2
n = 20 / 2
= 10
n = 10
The correct answer is
B. Let n = the number of DVDs rented; 20 + 4n = 6n; 10 videos
Describe a rigid motion or composition of rigid motions that maps the rectangular bench at (10,0) and the adjacent flagpole onto the other short rectangular bench and flagpole
Answers
Answer:
The answer is below
Step-by-step explanation:
Describe a rigid motion or composition of rigid motions that maps the rectangular bench at (0,10) and the adjacent flagpole onto the other short rectangular bench and flagpole
Solution:
The other short rectangular bench is at (0, -10), while the short flagpole at (2, 10)
Transformation is the movement of a point from its initial location to a new location. If an object is transformed then all its points are also transformed. Types of transformation are reflection, dilation, rotation and translation.
If a point X(x, y) is reflected across the x axis, the new point is (x, -y)
If a point X(x, y) is reflected across the y axis, the new point is (-x, y)
Therefore the rectangular bench at (0,10) is reflected across the x axis to give the other short rectangular bench at (0, -10) while the adjacent flagpole at (-2,10) is reflected across the y axis to give the other flagpole at (2, 10)
