purchased can be described with a function.
a Identify the input variable and the output variable in this function.
b. Describe the function with a sentence of the form is a function of_."
c Identify an input-output pair of the function and explain its meaning in this situation.
Answer:
A. $3.50 is input, Gallon of Gasoline is output B. The form is a function of y=3.50x C. $7.00-2 Gallons. This shows that for 7 dollars you can get 2 gallons of gasoline.

The linear equation will be y = 3.50 x. Then the total cost 'y' of the 'x' gallons of gasoline.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
At a gas station, a gallon of gasoline costs $3.50. The relationship between the dollar cost of gasoline and the gallons purchased can be described with a function.
Let 'x' be the number of gallons of gasoline and 'y' be the total cost. Then the equation is given as,
y = 3.50 x
The linear equation will be y = 3.50 x. Then the total cost 'y' of the 'x' gallons of gasoline.

At a local fair, Molly sells bracelets. It costs her
$10 per bracelet for supplies and the local marke
charges her a one-time booth fee of $60. She
charges $20 for each bracelet.
a) Write a system of equations to represent this
situation (one equation for expenses and one
equation for income):
Answer:
10x + 60 ; 20x
Step-by-step explanation:
Given that:
Purchase price per bracelet = $10
Cost of booth = $60
Selling price per bracelet = $20
Hence,
Let number of bracelets = x
Expense equation :
(Price per bracelet * number of bracelet) + booth fee
(10 * x) + 60
10x + 60
Income equation :
Selling price * number of bracelets
20x
Triangle L M N is shown. Angle M L N is a right angle. The length of M L is 5.74, the length of L N is 4, and the length of hypotenuse M N is 7. Law of cosines: a2 = b2 + c2 – 2bccos(A) What is the measure of AngleN to the nearest whole degree? 35° 45° 55° 65°
Answer:
55⁰
Step-by-step explanation:
A triangle is a polygon with three sides and three angles. There are different types of triangles such as isosceles triangle, equilateral triangle, scalene triangle, right angled triangle.
The law of cosines states that for a triangle with sides a, b and c and the corresponding angles opposite to the sides which are A, B and C. Then:
a² = b² + c² – 2bccos(A)
Let ML = a = 5.74, LN = b = 4, MN = c = 7.
∠N is opposite to side ML. Let ∠N be A, hence:
a² = b² + c² – 2bccos(A)
2bc* cos(A) = b² + c² – a²
Substituting:
2(4)(7) * cos(A)= 4² + 7² - 5.74²
56cos(A) = 32.0524
cos(A) = 0.5723
A = cos⁻¹(0.5723)
A = 55⁰
A = ∠N = 55⁰

If x varies directly with y and x = -3 when y = 12, what is the constant of variation?
Answer:
k = - [tex]\frac{1}{4}[/tex]
Step-by-step explanation:
Given that x varies directly with y then the equation relating them is
x = ky ← k is the constant of variation
To find k use the condition x = - 3 when y = 12
- 3 = 12k ( divide both sides by 12 )
[tex]\frac{-3}{12}[/tex] = k , that is
k = - [tex]\frac{1}{4}[/tex]

some soiled goods are sold for 2 /5 of their original price. what will be the selling price of a pair of trouser originally Costing#850.00
Answer:
$340.
Step-by-step explanation:
Given that some products, such as a pair of trousers in this case, are sold at 2/5 of their value, if the trousers cost $ 850, the following calculation must be performed to determine their sale value:
2/5 = 0.4
850 x 0.4 = X
340 = X
Therefore, selling them at 40% of their value, the trousers' sale value was $ 340.

There are a total of 64 students in a filmmaking club and a yearbook club. The filmmaking club has 14 more students than the yearbook club. a. Write a system of linear equations that represents this situation. Let x represent the number of students in the filmmaking club and y represent the number of students in the yearbook club.
Answer:
x + y = 64
x = y + 14
Step-by-step explanation:
Given:
Total number of student = 64
x = number of students in filmmaking club
y = number of students in yearbook club.
Computation:
So,
x + y = 64
And,
x = y + 14
So
Number of students in yearbook club = 25
Number of students in filmmaking club = 39
The system of linear equations is x + y = 64 and x = y + 14.
Given that,
The total number of students is 64 .Here we assume the x be the number of students in filmmaking club .And, y be the number of students in yearbook club.Based on the above information, the calculation is as follows:
x + y = 64
And,
x = y + 14
Therefore,
We can say that
Number of students in yearbook club = 25
And, the number of students in filmmaking club = 39

To find the precent of something you multiply it by 1/100th of what precentage youre trying to find. That's a really weird way of explaining it... It's easier to show with examples.
Some numbers you probably know off the top of your head (whats 100% of 5 or 50% of 20?) But you can also move the decimal place over twice. 100 becomes 1.00 and 1x5 is 5. Same with 50%, it turns into 0.50 or 0.5. and 0.5x20 is 10...
0.25 x 80 is 20 so 25% of 80 is 20
0.8 x 125 is 100 so 80% of 125 is 100
0.6 x 120 is 72 so 60% of 120 is 72
0.45 x 15 is 6.75 so 45% of 15 is 6.75
0.5 times 60 is 30 so 50% of 60 is 30
and for the shopkeeper
0.46 x 150 is 69 so he sold 69 newspapers (nice)
0.24 x 150 is 36 so he sold 36 pens
0.12 x 150 is 18 so he sold 18 books
and 0.18 x 150 is 27 so he sold 27 "other items"
we can check this by adding together the items sold
69+36+18+27=150
(this only works if they gave us 100% of the items sold)
You and a friend make a total of 63 bird houses. The ratio of bird houses you make to bird house your friend makes is 4 : 5 How many bird houses did your friend make?
Answer:
Your friend made 35 bird houses.
Step-by-step explanation:
If the ratio from your houses to your friends houses is 4:5, that means that for every 9 houses built, your friend did 5. So, every 18 houses built, your friend did 10. For every 27, your friend did 15, and for 36, your friend did 20, and for every 45, your friend did 25, and for every 54, your friend did 30, and for every 63, your friend did 35.
Which is the better buy: 4 cans of peaches for $6.44 or 3 cans for $4.71?
Answer:
3 cans for $4.71
Step-by-step explanation:
6.44/4= $1.61
4.71/3= $1.57
3 cans for $4.71 is the better buy
Answer:
4 cans is the better option because $6.44 divided by 4 is 1.61. And if you add $4.71 + $1.61 + $1.61 it would equal $7.43

Applying the function concept, it is found that the top right relation is not a function.
For a relation to be classified as a function, each value of the input may be related to only one value of the output.In the top right relation, the input of x = -3 is related to two values of the output, y = 4 and y = -2, which is why it does not represent a function.
