find the inverse of this function and verify by using the composition of functions
f(x)= -3/x-3
Answer:
f(x)^-1 = 3x-3/x
Step-by-step explanation:
f(x) =-3/x-3
y= -3/x-3
x=-3/y-3
-3= (y-3)x
-3= xy-3x
-xy=-3x + 3
y= -3x +3/x
y= 3x-3/x
f(x)^-1 = 3x-3/x

Answer:
see attached
Step-by-step explanation:
For values of x less than zero, the graph of the function is a graph of the line
y = -x
Because the function is defined by this expression at x=0, there will be a solid dot at the end of the line there, at (0, 0).
__
For values of x greater than 0, the graph of the function is a graph of the line
y = -x -2
This line has the same -1 slope as before, but has a y-intercept of -2. The function is not actually defined as (0, -2), so there is an open circle at the end of the line there.
-2g+1.5=17.3 My math final has this, my answer isn’t on my screen. Starting to think i dont know how to do math.
Answer:
Original: -2g + 1.5 = 17.3
Solving:
-2g = 15.8
-g = 7.9
Answer:
g = -7.9
And don`t worry I only know how to do this because I remember it from a few years ago. I`m not even caught up in my own math class ;--;
Hope that helps

On one particular day, Jamal arrived late to find four other co-workers waiting for him to arrive. They were unable to do other work because they had made arrangements to have their position covered and to work with Jamal on a special project. Nothing could be done until he got there. The other workers earned wages as followed: Derek earns $10.00/hr; Sam earns $11.80/hr; Penny earns $11.00/hr and Zachary earns $13.00/hr. How much was lost in unproductive wages because Jamal arrived 15 minutes late?
Answer: $11.45
Step-by-step explanation:
Arriving 15minutes late simply means 15/60 = 1/4 of the wages has been lost. We then multiply 1/4 by each person's wage. This will be:
Derek = 1/4 × $10.00
= $2.50
Sam = 1/4 × $11.80
= $2.95
Penny = 1/4 × $11.00
= $2.75
Zachary = 1/4 × $13.00
= $3.25
The amount lost will be:
= $2.50 + $2.95 + $2.75 + $3.25
= $11.45

What is the distance between points A (-2, 1) and B (2, 4)?
Answer:
5
Step-by-step explanation:
A(-2 , 1) ; B(2 , 4)
[tex]Distance = \sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}\\\\[/tex]
[tex]= \sqrt{(2-[-2])^{2}+(4-1)^{2}}\\\\= \sqrt{(2+2)^{2}+(4-1)^{2}}\\\\= \sqrt{(4)^{2}+(3)^{2}}\\\\= \sqrt{16+9}\\\\= \sqrt{25}\\\\= \sqrt{5*5}\\\\= 5[/tex]

Step-by-step explanation:
Distribute #5 among j and -5
why is b the answer ???????????????????/
Answer:
Step-by-step explanation:
its b cuz when u replace any value of x from B to the equation, the value of y satisfies the values of y in B. For instance
y = 4 * -3 + 2
= -10
the value of y is -10 which satisfies the value of y in B but when u use a value of another table suppose A it would be,
y = 4 * 7 + 2
= 30
but the value y corresponding to the value of x we used is not 30

2 5/6 years is how many months
Final Answer: 34 months
Steps/Reasons/Explanation:
Hey there! Each year is 12 months. We can see that 2 years is already given. 2 years × 12 months = 24 months.
For [tex]\frac{5}{6}[/tex] we will multiply it by two to find the remaining amount of months. [tex]\frac{5}{6}[/tex] × [tex]2[/tex] = [tex]\frac{10}{12}[/tex]. This means that there is an extra 10 months of a year remaining.
Now we have to add them up. 24 months + 10 months = 34 months.

Answer:
y=-3x+6
Step-by-step explanation:
(y-y1)=m(x-x1)
m=(y2-y1)/(x2-x1)
m=(-3-6)/(3-0)
m=(-9)/(3)
m=-3
(choose whichever point for the first formula, i will be using(0,6))
(y-6)=-3(x-0)
y-6=-3x
y=-3x+6

Answer:
The third Number line = C
P = - 1 ; Q = 7
Step-by-step explanation:
P = - 1 ; as the tick marks are 1 unit apart ; hence the point P is located either side of - 2 and 0 ; therefore, the point Q is either :
(-2 + 1) = - 1 or (0 - 1) = - 1
Q = 7 ; Q is position on between 6 and 8 ; therefore, the number which falls in the middle of both numbers is 7.

Answer:
The answer is "70 and 2200".
Step-by-step explanation:
Please find the complete question in the attached file.
The total payment = y
The number of copies to be sold = x
[tex]\to y = 70x + 2200[/tex]
In part (a):
Change of pay = discrepancies between (x+1) sale and (x) sale of copies for every copy sold
[tex]=[70(x+1) + 2200] - [70x + 2200] \\\\= 70x + 70 + 2200 - 70x - 2200\\\\= 70\\\\[/tex]
In part (b) :
[tex]\to y = 70x+ 2200[/tex]
when [tex]x = 0[/tex]
[tex]\to y = 70(0) + 2200\\\\[/tex]
[tex]=0+2200\\\\=2200[/tex]

Answer:-35
Step-by-step explanation: 7x5 = 35, but since the 5 is a negative it’s -35
Answer:
-35
Step-by-step explanation:
whenever multiplying positive and negative integers, if one of the factors are negative, then the answer will be negative. if both are negative, the answer becomes a positive, and if both are positive, the answers stays positive.
in this case 7 is positive and 5 is negative so your anwers is -35
