Option BStep-by-step explanation:
Definition of variables: Variables are terms that have no coefficients.
To look for variables in the expression 2w + 11t + 4y, simply look for the variables (letters) in the expression. We can see that the variables are w, t, and y, which matches Option B.
Hence, Option B is correct.
Describe the transformation f(x) = Vx+ 1 - 5 in words.
The parent function f(x) = V has been shifted
1 unit and
5 units
Answers
Answer:
The translation is 1 unit to the left and 5 units down
Step-by-step explanation:
The explanation is given below;
Given that
The transform function is [tex]f(x) = \sqrt{x+1} - 5[/tex]
It can be seen that
The parent function is
[tex]f(x) = \sqrt{x}[/tex]
After that
The parent function would be transform 1 units to the left [tex]\sqrt{x+1}[/tex]
And afterwards it would be transform in 5 units down [tex]\sqrt{x+1} - 5[/tex]
So
The parent function [tex]f(x) = \sqrt{x}[/tex] would be translate in 1 unit to the left and 5 units down
Answer:
The translation is 1 unit to the left and 5 units down

Rick Arico invested $5000; part at a yearly rate of 7% and part at a yearly rate of 9%. The total
interest earned for one year was $368. How much did he invest at each rate?
Answers
Answer:
Rick Arico invested $4100 at a yearly rate of 7% and $900 at a yearly rate of 9%.
Step-by-step explanation:
Let x represent the amount invested at 7% yearly rate and let y represent the amount invested at 9%.
$5000 was split and invested at 7% yearly rate and 9% yeatly rate. Therefore:
x + y = 5000 (1)
For the 7% yearly rate:
Interest = (x * 7%) = 0.07x
For the 9% yearly rate:
Interest = (y * 9%) = 0.09y
The total interest = interest for the 7% yearly rate + Interest for the 7% yearly rate = 0.07x + 0.09y
Given that the total interest earned in the year was $368, hence:
0.07x + 0.09y = 368 (2)
To find x and y, we have to solve equation 1 and equation 2 simultaneously. multiply equation 1 by 0.07 and subtract the result from equation 2 to get:
0.02y = 18
y = 18 / 0.02
y = $900
Substitute y = $900 in equation 2:
0.07x + 0.09(900) = 368
0.07x + 81 = 368
0.07x = 287
x = $4100
Therefore Rick Arico invested $4100 at a yearly rate of 7% and $900 at a yearly rate of 9%.

If a graph is reflected across y = x then it will be an inverse graph so graphs B and C will be inverse.
What is the inverse of a function?The inverse of a function is basically a reverse function or undo of the function.
For example y = f(x) then inverse will be x = f(y).
It means in the inverse function we need to interchange x and y.
Another example y = 3x² ⇒ x = √(y/3) will be the inverse.
An inverse function is a reflection of graph across y = x and due to that coordinate will interchange its that ;
( x ,y ) → ( y , x )
Since graph A is rotated about the x-axis to make graph B
Now,
Graph A is rotated( which is B ) and reflected across the axis y = x to form Graph C.
So B and C will be the inverse of each other.
Hence "If a graph is reflected across y = x then it will be an inverse graph so graphs B and C will be inverse".

A man realizes he lost the detailed receipt from the store and only has the credit card receipt with the after-tax total. If the after-tax total was $1,413.10, and the tax rate in the area is 8.7%, what was the pre-tax subtotal?
Answers
Answer:
The pre-tax amount was $1300.
Step-by-step explanation:
Given that:
After-tax total = $1413.10
Tax rate in the area = 8.7%
The pre-tax price would be 100% and this tax rate is an addition.
Total percent = (100+8.7)% = 108.7%
Let,
x be the pre-tax amount.
108.7% of x = 1413.10
[tex]\frac{108.7}{100}x=1413.10\\1.087x = 1413.10[/tex]
Dividing both sides by 1.087
[tex]\frac{1.087x}{1.087}=\frac{1413.10}{1.087}\\x= 1300[/tex]
Hence,
The pre-tax amount was $1300.

The answer is B
Step-by-step explanation:
• Water tank A has 220 gallons of water and is being drained at a constant rate of 5 gallons per minute.
• Water tank B has 180 gallons of water and is being drained at a constant rate of 3 gallons per minute.
Part
How much time, in minutes, do water tank A and water tank B have to be drained in order for them to have the same amount of water?
Answers
Answer: In 20 minutes, tanks A and B will each have 120 gallons remaining in them.
Step-by-step explanation:
The equation, the amount at which they will be equal, represents the given starting amounts minus the gal/min times the unknown time in minutes, m.
220 - 5m = 180 - 3m Subtract 180 from both sides; add 5m to both sides.
220-180 -5m +5m = 180-180 +5m - 3m Combine like terms
40 = 2m Divide both sides by 2
20 = m
Check: Substitute 20 for m in the equation
220 - 5(20) = 180 - 3(20)
220 - 100 = 180 -60
120 = 120 True!
One lap around a track is equal to 1/4 of a mile. A horse ran a distance of 9 laps in 2 minutes and 30 seconds. What was the horse's average speed in miles per minute? Need Help!!
Answers
So the horse ran 2.25 miles in 150 seconds
To find the mile time in seconds divide 150 by 2.25 which equals 66.7sec per mile but it’s asking miles per minute and one mile is over a min so he runs Less than one mile per minute. So now you must divide 60 by 66.7 to find that he runs .89 miles per min.
