Gabriel is shipping a package of golf balls to his father for his birthday present. Each golf ball weighs 1.6 oz and the package he is shipping them in weighs 15 oz . The function f(x)=1.6x+15 represents this problem situation . In this function , what does the x represent
Answers
Answer:
x represents the number of golf balls in the packageStep-by-step explanation:
Given that the function is f(x)=1.6x+15,
we can see that the function corresponds to the equation of a straight line
that y=mx+c
now comparing this function with the equation of a straight line
f(x)=1.6x+15
y=mx+c
we can see that
x represents the number of golf balls in the package
15 is constant c which is the weight of the package used in the shipping
If a function is defined by the equation y=12x−32, which equation defines the inverse of this function?
A. y=2x+3
B. y=2x+32
C. y=2x−3
D. y=2x−32
Answers
Answer:
A. Y=2x+3
Step-by-step explanation:
because im right
If a function is defined by the equation y = 2x−32, the equation that defines the inverse of this function would be: B. y=2x+32
How to determine the inverseTo determine the inverse of the function, we would first replace x with y in the function:
y = 2x - 32
x = 2y - 32
x + 32 = 2y
Divide both sides by 2
x/2 + 32/2 = y
f−1(x) = x/2 + 32/2
The common facot between the denominatoes of the values is 2. So, when expanded, we have;
(x + 32)/2
So, the closest option that represents the inverse is B. y=2x+32.

what is an equation of the line that passes through the points (-4, -3) (7, 8)
Answers
Answer:
y = x + 1
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 4, - 3 ) and (x₂, y₂ ) = (7, 8 )
m = [tex]\frac{8-(-3)}{7-(-4)}[/tex] = [tex]\frac{8+3}{7+4}[/tex] = [tex]\frac{11}{11}[/tex] = 1 , then
y = x + c ← is the partial equation
to find c substitute either of the 2 points into the partial equation
using (7, 8 ) , then
8 = 7 + c ⇒ c = 8 - 7 = 1
y = x + 1 ← equation of line

I attached a pic to show u !! Blue is the parent function and red is the other equation so it's easy to see how they compare to one another.
how to read a function different from the parent
that negative in front of the (x-2)^4 gets distributed and the equatuin will then look like (-x+2)^4that negative in the front means to flip the proabla on the axis !! and the +/- will tell u how it will be translated by however many units keep in mind u go the opposite of this sign inside the parenthesis. so for example if it's - 2 ur not going to go to the left 2 units you're going to go to the RIGHT 2 units and vice versa!! another thing remember that if it's inside the parenthesis it's the x-axis !! if outside then it's y-axis example: (3+4)^4+3 look inside the parenthesis, that tells me that it's not going to flip on the x axis cause and im going to translate to the left 4 units ! cause remember u go the opposite.and that +3 will tell me to go UP 3 units and that tells me how to translate on the y axis!!

. In a soccer league, each of the n participating teams plays every other team twice during the season. If in the next season the league increases the number of teams by two, then there would be 27.5% more matches played. Find
Answers
The number of teams and matches in the soccer league illustrates permutation and combination
There are 12 teams in the soccer league in the first season
How to determine the number of teamsThe number of teams in the soccer league is given as n.
So, the total number of matches played in a season is:
Matches = n(n-1)/2
When the number of teams increases by 2, we have:
Matches = (n + 2)(n + 2 -1)/2
Also, the number of matches increases by 27.5%.
So, we have:
Matches = n(n-1)/2 * (1 + 27.5%)
Equate both equations
[tex]\frac{(n + 2)(n + 2 -1)}{2} = \frac{n(n-1)}{2} * (1 + 27.5\%)[/tex]
Simplify
[tex]\frac{(n + 2)(n + 1)}{2} = \frac{n(n-1)}{2} * (1.275)[/tex]
Multiply through by 2
[tex](n + 2)(n + 1) = n(n-1) * (1.275)[/tex]
Expand
[tex]n^2 + 3n + 2 = 1.275n^2 - 1.275[/tex]
Collect like terms
[tex]n^2 -1.275n^2+ 3n + 2 +1.275 = 0[/tex]
Evaluate the like terms
[tex]-0.275n^2+ 3n + 3.275 = 0[/tex]
Using a graphing calculator, we have:
n = -1 or n = 11.909
n cannot be negative.
So, we have:
n = 11.909
Approximate
n = 12
Hence, there are 12 teams in the soccer league in the first season

I really hope this helps!
The value represents the is D(-5,5), E(-3,4), F(-6,0), G(-8,1) (-8,1) . A rectangle is a quadrilateral with four right angles in the Euclidean plane.
What is meant by rectangle?A rectangle is a quadrilateral with four right angles in the Euclidean plane. A parallelogram with a right angle or an equiangular quadrilateral, where equiangular means that all of its angles are equal, are other ways to describe it. A rectangle with four equally length sides is a square.
An enclosed 2-D shape called a rectangle has four sides, four corners, and four right angles (90°). A rectangle has equal and parallel opposite sides. A rectangle has two dimensions—length and width—because it is a two-dimensional form.
Given,
vertices D(61), E(8,0),
F(5.-6), and G(3-5); (x, y)(x-11, y + 4)
Because the rule is (x-11, y+4), you must subtract 11 from x, which is the first number in the parenthesis, and then add 4 to y.
D(-5,5), E(-3,4), F(-6,0), G(-8,1) (-8,1)

Maddy received $60 for her birthday and decided to go shopping. She bought 2 shirts priced at $12.25 each, a necklace for $8.50, and a pair of shoes for $22.75. If all the prices included tax, and she gave the cashier all of her birthday money, how much change did she get back?
Answers
Answer:
$3.75
Step-by-step explanation:
Cost of one shirt = $12.25
cost of two shirt = 2*Cost of one shirt= 2*$12.25 = $25
cost of necklace = $8.50
cost of pair of shoes = $22.75
Total cost for the shopping = cost of two shirt+cost of necklace+ cost of pair of shoes
Total cost for the shopping = $25 + $8.50+ $22.75 = $56.25
Given that Maddy had done total shopping worth $56.25 but she gave cashier all her birthday money which is equal to $60.
Then , cashier will return all the money from $60 exceeding $56.25
change returned to money = money given to cashier - total cost for shopping
change returned to Maddy = $60 - $56.25 = $3.75
Thus, Maddy got Back $3.75

The increment of £16470.45 by 13.5% is £18693.96.
PercentageWhat is percentage?A part per hundred is what the percentage denotes. The symbol '%' is used to symbolise it. Example percentages include: 10% is represented as the fraction 1/10.
Calculate the percentage:The amount is given as £16470.45.
As, the amount is increased by 13.5%.
Thus 13.5% of £16470.45 will be calculated as,
= 16470.45 ×(13.5/100)
= 2223.51
Thus, the 13.5% of the amount will be £2223.51
Calculate the increment of the amount:As, the incremented amount is calculated as £2223.51.
