y + 2/5y= y (1 + 2/5)
= 7/5 y
y - 0.32 y (just add)= 1y - 0.32y
= 0.68 y
y - 2/5y
= y (1 - 2/5)
= 3/5 y
y + 0.32 y (just add)
= 1y + 0.32y
= 1.32 y

A recycling center was offering cash for different types of recyclables. For each pound of paper recycled they offered $1.41, for each pound of aluminum they offered $1.53 and for each pound of plastic they offered $0.33. Jerry took in 5 pounds of paper, 15 pounds of aluminum and 6 pounds of plastic. How much money did he earn?
Answer:
Total amount earn = $31.98
Step-by-step explanation:
Given:
Cost of paper = $1.41
Cost of aluminium = $1.53
Cost of plastic = $0.33
Amount of paper = 5 pound
Amount of aluminium = 15 pound
Amount of plastic = 6 pound
Find:
Total amount earn
Computation:
Total amount earn = ($1.41)(5) + ($0.33)(6) + ($1.53)(15)
Total amount earn = $7.05 + $1.98 + $22.95
Total amount earn = $31.98
2 1/3 ÷y=1 2/5 ÷(−1.1)
Answer:

If has a decimal approximation of 3.4, then is between which two integers? In your final answer, include all calculations.
Answer: It is between 3 and 4.
Step-by-step explanation:
Integers are whole numbers and its opposite, for example, -5,-4,-3,-2,-1, 0, 1,2,3,4, 5 ,....
Meaning that 3.4 is not an integer so it fall between two integers and those integers has to be positive because 3.4 is a positive number.
3.4 is slightly greater than 3 but is less than 4.
Meaning that 3.4 is between the integers 3 and 4.

Step-by-step explanation:
all functions are relations but why not all relations are functions
Answer:
All functions are relations, but not all relations are functions. A function is a relation that for each input, there is only one output. Here are mappings of functions. The domain is the input or the x-value, and the range is the output, or the y-value.
Answer:
Step-by-step explanation:
A relation between members of two sets X and Y is any set of ordered pairs {(x1,y1) (x2,y2) … }, finite or infinite in their number, provided the first member is from X and the second member is from Y. (Let’s not mention the uncountable possibility here).
E.g., if X = {Sunday, Monday, …, Saturday} and Y = {1,2, …, 31}, then the set {(Monday,1) (Tuesday,2) … (Monday,8) (Tuesday,9) … (Sunday,28)} is a useful relation for some February calendar, somewhere. It is “one-to-many”. And note that set Y need not be covered, but X must be. This distinguishes the domain of the relation (days of the week here) from its codomain (whole numbers 1 to 31 here).
Considering the vast set of all relations, there is one subset of great importance, those relations that have unique codomain values for each domain value. That is, each x in X is paired unambiguously with exactly one y in Y. These special relations are functions. The set of y in Y which have been paired with some x in X is called the range of f. Functions may still be “many-to-one”, as in y = r(x) which gives x rounded to the nearest integer. Thus r(2.3) = r(1.9) = 2.
Within the subset of functions are the one-to-one functions, which also have the property that every y in the range is paired with exactly one x in the domain. Because of this, these are the only functions that have an inverse function. Thus, the inverse function can be written as {(y1,x1) (y2,x2) … }. This shows that the domain and range of the original function are exactly exchanged in the inverse function.
E.g., y = tan(x) is one-to-one with domain [-pi/4 , pi/4] and range [-1,1]. Its inverse is x = arctan(y) with domain [-1,1] and range [-pi/4 , pi/4]. The roles of x and y are unambiguous, and shouldn’t be exchanged: x always in [-pi/4 , pi/4] and y always in [-1,1].

A line has the following equation: y=\frac{6}{7}x+5y=
7
6
x+5
What is the slope of a line parallel to the given line?
Question Blank
type your answer...
What is the slope of a line perpendicular to the given line?
Question Blank
type your answer...
Answer:
Step-by-step explanation:
I'm still not exactly sure what the question really is, but the level suggests that it is
y = (6/7)x + 5
Any line that is parallel to this line has a slope of 6/7
Any line that is perpendicular to this line is a little more complicated.
slope of given line * slope of perpendicular line = - 1
6/7 * perpendicular slope = - 1
Multiply by 7
6*perpendicular slope = - 7
Divide by 6
perpendicular slope = - 7/6
There were some people on a bus. Half of the people get off at the first stop and 11 people get on. Now there are 20 people on the bus. How many people were on the bus to begin with?
Answer:
18 people
Step-by-step explanation:
18/2=9
9+11=20
Answer:
18.
Step-by-step explanation:
this is because in order to find out how many were on the bus, you simply do 20 - 11 = 9. Than you must multiply 9 by 2 which equals 18. That gives you your answer.
Which numbers are rational?
Answer:
1, 4, 5
Step-by-step explanation:
a rational number is defined as a number that can be written as a fraction. so, 4 and 5 are automatically checked off. 1 also simplifies to plus or minus 11, which is a whole number, meaning it is automatically rational. 2 is not rational because there is no set pattern in the decimal, so it can not be written as a fraction. 3 is the same thing, so it is irrational.
6 is greater than or equal to 9, is that the same thing as ALL REAL NUMBERS?
Answer:
No it is not the same
Step-by-step explanation:
A real number is any number, positive or negative, whole number or decimal.
(EX) 1, 1.00567, -2, -2.659365
Any number!

Stock Market At the beginning of the day the stock market goes down 50 3/4 points and stays at this level for most of the day. At the end of the day the stock market goes up 120 1/2 points from the at the beginning of the day. What is the total change in the stock market from the beginning of the day to the end of the day?
Answer:
69 3/4
Step-by-step explanation:
The stock market goes down to 50 3/4 at the beginning of the day
At the end of the day it goes up to 120 1/2
Therefore total change in the stock market from the beginning to the end of the day can be calculated as follows
= 120 1/2 - 50 3/4
= 241/2 - 203/4
= 279/4
= 69 3/4
Hence the total change in the stock market from the beginning to the end of the day is
69 3/4
The dance team traveled to a competition and traveled in two vans. The first van transported 2 adults and 5 students and cost $77. The second van transported 2 adults and 7 students and cost $95. Find the cost for one student to enter the competition.
Answer: $9
Step-by-step explanation:
Let the cost for adults be a
Let the cost for students be b.
The first van transported 2 adults and 5 students and cost $77. This will be:
2a + 5b = $77
The second van transported 2 adults and 7 students and cost $95. This will be:
2a + 7b = $95
2a + 5b = 77 ...... equation i
2a + 7b = 95 ........ equation ii
Subtract equation ii from I
-2b = -18
b = 18/2
b = $9
An student cost $9
Put the value of b into equation i
2a + 5b = 77
2a + 5(9) = 77
2a + 45 = 77
2a = 77 - 45
2a = 32
a = 32/2
a = 16
An adult costs $16
A point moves in the plane in the following sequence.
A point moves down 2 units, reflects over the x-axis, moves right 4 units, and then reflects over the y-axis.
Which of the following points follows the sequence and has the same starting and ending point?
A. (2, 3)
B. (–1, 1)
C. (–3, –3)
D. (–2, 1)
Answer:
D
Step-by-step explanation:
The answer is point D(-2,1).
1. If the point D was moved down 2 units, then its coordinates became (-2,-1).
2. If point (-2,-1) was reflected over the x-axis, then its coordinates became (-2,1).
3. If the point (-2,1) was moved 4 units to the right, then its coordinates became (2,1).
4. If point (2,1) was reflected over y-axis, its coordinates became (-2,1).

1. given w(x)=4x
a. graph r(x)=4 x w(x). then complete the table of corresponding points on r (x).
Answer:
Step-by-step explanation:
a). When graph w(x) is transformed to r(x) = 4 × w(x), graph of w(x) is vertically stretched by a scale factor of 4.
Table for the corresponding points will be,
x w(x) r(x)
0 0 0×4 = 0
15 60 60×4 = 240
30 120 120×4 = 480
45 180 180×4 = 720
b). As discussed in part (a), graph of w(x) will be vertically stretched by a scale factor of 4 to produce the graph of r(x).
c). Since, w(x) = 4x
and r(x) = 4[w(x)]
r(x) = 4(4x) = 16x
r(x) = 16x
Kyle had cable television installed in his house. At the time of installation, there was an initial charge of $199 for the cable box and a setup fee of $49. There is a monthly charge of $79 for cable services. His total bill over a certain number of months, m, was $880. Choose an equation that represents the total costs of Kyle's cable installation and monthly charge. Then, choose the number of months he has had cable
Answer:
The equation is [tex]199+49+79m=880[/tex]
Kyle has had cable for 8 months.
Step-by-step explanation:
Let m denotes number of months cable services have been used.
Initial charge for the cable box = $199
Setup fee = $49
Monthly charges for cable services = $79
Also,
Total bill over a certain number of months, m = $880
Therefore,
[tex]199+49+79m=880[/tex]
Now solve the equation.
[tex]199+49+79m=880\\248+79m=880\\79m=632\\m=\frac{632}{79}\\ m=8[/tex]
That is Kyle has had cable for 8 months.

Answer:
h=−6.28r2+s/6.28r
Step-by-step explanation:
Step 1: Flip the equation.
6.28hr+6.28r2=s
Step 2: Add -6.28r^2 to both sides.
6.28hr+6.28r2+−6.28r2=s+−6.28r2
6.28hr=−6.28r2+s
Step 3: Divide both sides by 6.28r.
6.28hr/6.28r=−6.28r2+s/6.28r
h=−6.28r2+s/6.28r
