Answer:
y = 2x + 1/3
Step-by-step explanation:
Since the line is parallel to y = 2x - 5, its slope is also 2x, as parallel lines have the same slope, leaving you with y = 2x.
Since it intercepts the y-axis at 1/3, and y = 2x intercepts the y-axis at 0, you will now need to add a 1/3 to the end of the equation for it to intersect the y-axis at the right place.
Therefore, the equation is: y = 2x + 1/3

The drama club is selling tickets to their play to raise money for the show's expenses. Each student ticket sells for $4 and each adult ticket sells for $8. There was a total of $640 in revenue from the sale of 100 total tickets. Graphically solve a system of equations in order to determine the number of student tickets sold, x, and the number of adult tickets sold, y.
Answers
Answer:
number of student tickets sold (x) = 40
number of adult tickets sold (y) = 60
Step-by-step explanation:
Let x = number of student tickets sold
Let y = number of adult tickets sold
Given:
total ticket sales = 100⇒ x + y = 100
Given:
student ticket = $4adult ticket = $8total ticket sales = $640⇒ 4x + 8y = 640
Rewrite x + y = 100 to make x the subject:
⇒ x = 100 - y
Substitute x = 100 - y into 4x + 8y = 640 and solve for y:
⇒ 4(100 - y) + 8y = 640
⇒ 400 - 4y + 8y = 640
⇒ 4y = 240
⇒ y = 60
Substitute found value for y into x = 100 - y and solve for x:
⇒ x = 100 - 60
⇒ x = 40
To solve graphically, rewrite both equations to make y the subject:
y = 100 - x
y = 80 - (1/2)x
Plot both lines.
The solution is the point of intersection (40, 60)

What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
The measure of angle m is 7 degrees less than the measure of angle n.
m = n - 7 ...(I)
The sum of the measures of the two angles is 59°
m + n = 59 ...(II)
Solving the above two linear equations in two variables by substitution method:
n - 7 + n = 59
2n = 66
n = 33
m = 33 - 7 = 26
Thus, the measure of each angle are 33 and 26 if the measure of angle m is 7 degrees less than the measure of angle n.

Kenny pays $50.00 for a total of 12 books. If each book cost the same, how much was each book?
Answers
Answer:
x= 4 1/6
Step-by-step explanation:
1. Create equation
12x=50
2. Solve
12x/12=50/12
x=4 1/6
3. Check
12x4 1/6=50
12x50/12=50
50=50
Correct!
4. Answer
x= 4 1/6
12x = $50.00, where x is our unknown, or the cost of each individual book.
Divide 12 from both sides:
12x/12 = $50.00/12
x = 4.1667
So, the total cost of each book is around $4.17!

the winnings.
Answers
Hey there!
Add the total of Bruce, Cathy and Dilip
=> 7 + 10 + 15
=> 25
Then, Divide it by 600
=> 600 ÷ 25

To find how much Bruce's share
we multiply 24 times the $10 he contributed
=> 24 × 10
=> 240
Therefore, Bruce's share would be $240

What are some basic properties of exponentiation?If we have [tex]a^b[/tex] then 'a' is called base and 'b' is called power or exponent and we call it "a is raised to the power b" (this statement might change from text to text slightly).
Exponentiation (the process of raising some number to some power) have some basic rules as:
[tex]a^{-b} = \dfrac{1}{a^b}\\\\a^0 = 1 (a \neq 0)\\\\a^1 = a\\\\(a^b)^c = a^{b \times c}\\\\ a^b \times a^c = a^{b+c} \\\\^n\sqrt{a} = a^{1/n} \\\\(ab)^c = a^c \times b^c\\\\a^b = a^c \implies b = c \text{ (if a, b and c are real numbers and } a \neq 1 \: and \: a \neq -1 )[/tex]
For this case, we have got the equation as:
[tex]3^{2x+1} = 3^{x+5}[/tex]
Using the property that: [tex]a^b = a^c \implies b = c \: \:(if \: a \neq 1 \: and \: a \neq -1)[/tex], we get:
[tex]2x + 1 = x + 5\\[/tex]
Solving it further:
[tex]2x + 1 = x + 5\\\\\text{Subtracting 1+x from both the sides}\\\\2x + 1 - (1+x) = x+5 - (1+x)\\x = 4[/tex]
Thus, the value of x for the considered algebraic equation is 4.

An equation that models the decline in the number of US farms is y=3,962,000e−0.02t where t is the number of years since 1960 and y is the number of farms.
Answers
The decline in the number of farms means there is a reduction in the number of farms
The number of US farms after 5 years is 3584818
How to determine the number of farmsThe equation that represents the number of farms is given as:
[tex]y=3962000e^{-0.02t[/tex]
After 5 years, the value of t is 5.

James has $10 in 5-cent and 10-cent coins in his change jar and counts 157 coins in total. How many 10-cent coins does he have?
Answers
Answer:
Step-by-step explanation:
Let the number of 5-cent coins he has be x and the number of 10-cent coins he has be y
x coins + y coins = 157 coins
(x × 5)cents + (y × 10)cents = $10
These two equations are true about the money he has, i.e
x + y = 157
5x + 10y = 1000
(We made the $10 into 1000 cents because the coins are in cents)
We can solve the above equations either simultaneously or through substituting.
Simultaneously:
(x + y = 157) × 5
5x + 10y = 1000
5x + 5y = 785
5x + 10y = 1000
Subtract the co-efficients in the equations
0x + -5y = -215
-5y = -215
y = 43
This means he has 43 10-cent coins.
PS: We get the number of 5-cent coins by subtracting 43 from 157, the total number of coins he has.
Substituting:
x + y = 157
5x + 10y = 1000
y = 157 - x
5x + 10(157 - x) = 1000
5x + 1570 - 10x = 1000
-5x = -570
x = 114 coins
157 - 114 = 43 coins
Thus there are 43 10-cent coins.
Answer:
46
Step-by-step explanation:
You would have 46 10-cent coins. First split it up into dollars, there are $10 and 10 dimes in each dollar. So if James has 157 coins you would need to first see how many coins he has in total. In total there are 100 dimes. We need to get to 157 coins so we'll need to break up some of the coins. So we keep turning the dimes into nickels until we get the number 157 for all the coins in total. So James has 46 10-cent coins.

It tells us to shift -6 units horizontally. This means we should shift point A to the left 6 units.
Then it wants us to reflect over the x-axis. The x-axis is the horizontal line. Flipping it across just means changing the x value to the opposite.

Answers
In a parallelogram the 4 angles need to sum to 360 degrees. There are two sets of identical angles, so one of the other angles would also be 80 degrees.
Now find the other two angles:
360 - 80 - 80 = 200 degrees
200 degrees / 21 = 100 degrees each.
The other 3 angles are: 80, 100 and 100
