What is a function?A function can be defined as the outputs for a given set of inputs.
The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.
Given, Barbara signed up for dance lessons at Dance Unlimited. She was charged $55 per month for lessons and a one-time recital fee of $165.
Let m be the no of months and f(m) is the total cost.
∴ f(m) = 55m + 165.
The equation represents the $495 total cost,
∴ 495 = 55m + 165.
55m = 330.

decrease 5% by 2205
Answers
Answer:
The answer is,2094.75
Step-by-step explanation:
Percentage decrease = 5% × 2,205
2,205 - Percentage decrease =
2,205 - (5% × 2,205) =
2,205 - 5% × 2,205 =
(1 - 5%) × 2,205 =
(100% - 5%) × 2,205 =
95% × 2,205 =
95 ÷ 100 × 2,205 =
95 × 2,205 ÷ 100 =
209,475 ÷ 100 =
2,094.75
Or to be simpler
You find 5% of 2,205 which is 110.25 then subtract it from 2205 which is 2,094.75 and that 5% of 2,205

Answer:
To find the points, remember the definition of distance or difference.
First, the 5 is easy to find, is in the extreme right.
Now, the next number is 3.
The difference between 3 and 5 is:
3 - 5 = - 2
This means that the place of the 3 will be 2 units at the left of the 5.
The next number is -2
The difference between -2 and 5 is:
-2 - 5 = -7
This means that the -2 is located 7 units at the left of the 5.

In a game you have 1/20 probability of winning $76 and a 19/20 probability of losing $9. What is your expected value?
Answers
Answer:
1
Step-by-step explanation:
The expected value for the given case is $-4.75.
What is probability?Probability is the branch of Mathematics that deals with the measurement of the chance of occurrence of a random event.
The probability of any event always lies in the close interval of 0 and 1 [0,1].
Given that,
The probability of winning $76 is 1/20.
And, the probability of losing $9 is 19/20.
The expected value for the given probability can be given by taking the product of the probability and the wining or losing amount and then substracting them as,
Expected value = 1/20 × 76 - 19/20 × 9
= 3.8 - 8.55
= -4.75
Hence, the expected value of amount for losing and winning the game is $-4.75.

The reaction of the body to a dose of medicine can sometimes be represented by an equation of the formR = M^2 (C/2- M/3),where C is a positive constant and M is the amount of medicine absorbed in the blood. If the reaction is a change in blood pressure, R is measured in millimeters of mercury. If the reaction is a change in temperature, R is measured in degrees, and so on. Find dR/dM. This derivative, as a function of M, is called the sensitivity of the body to the medicine.
Answers
Answer:
The derivative is [tex]\frac{dR}{dM} = CM - M^2[/tex]
Step-by-step explanation:
From the question we are told that
The equation representing the reaction is [tex]R = M^2 (\frac{C}{2} - \frac{M}{3} )[/tex]
Generally this equation can be represented as
[tex]R = \frac{C M^2}{2} - \frac{M^3}{3}[/tex]
Generally [tex]\frac{dR}{dM}[/tex] as a function of M is mathematically represented as
[tex]\frac{dR}{dM} = 2 * \frac{C M^{2 - 1 }}{2} + 3 * \frac{M^{3-1}}{3}[/tex]
=> [tex]\frac{dR}{dM} = CM - M^2[/tex]

4x-5y+16 =0
2x+y-6 =0
bicol method)
Answers
Answer:
Step-by-step explanation:
Given the simultaneous equation
4x-5y+16 =0 ....... 1
2x+y-6 =0 ...... 2
Let us solve to get the variable x and y:
The equation becomes
4x-5y =-16 ........ * 1
2x+y =6 ...... *2
Using Elimination method
Multiply eqn 1 by 1 and eqn 2 by 2
4x-5y =-16
4x+2y =12
Subtract resulting equation
-5y-2y = -16-12
-7y = -28
solve for y
-7y/-7 = -28/-7
y = 4
Substitute y = 4 into equation 2 to get x
2x+y =6
2x + 4 = 6
2x = 6-4
2x = 2
x = 2/2
x = 1
hence x is 1, y is 4
Beth and Pam both did some babysitting in the summer. Pam earned $4 less than 3 times as much as Beth. Together they earned $860. How much money did each person earn babysitting?
Answers
======================================================
Work Shown:
B = amount Beth earned
P = amount Pam earned
amounts are in dollars
Pam earned $4 less than 3 times as much as Beth, so,
P = 3B-4
Together they earned $860, meaning
P+B = 860
Plug the first equation into the second. Solve for B
P+B = 860
3B-4+B = 860
4B-4 = 860
4B = 860+4
4B = 864
B = 864/4
B = 216
Use this to find P
P = 3B-4
P = 3*216-4
P = 648-4
P = 644
Beth earned $216 and Pam earned $644.
----------------------------------------
Check:
B+P = 860
216+644 = 860
860 = 860
First equation is true
P = 3B-4
644 = 3*216-4
644 = 644
Second equation is true
Both equations are true when (B,P) = (216,644) so the solutions have been confirmed.
