You and 3 friends go to the movies. Each movie ticket costs $6.25. If your mom gave you $20.00 and you bought popcorn for $3.50, how much change are you taking home?
Answer:
[tex]Change = \$10.25[/tex]
Step-by-step explanation:
Given
[tex]Individuals = 4[/tex] (You and 3 friends)
[tex]Total = \$20.00[/tex]
[tex]Movie = \$6.25[/tex] per individual
[tex]Popcorn = \$3.50[/tex]
Required
Determine the change
First, we need to determine the total amount spent on movie ticket.
The question does not state whether I pay for my friend's ticket.
So, we'll work on what is obvious.
i.e
[tex]Amount\ Spent\ on\ Ticket = \$6.25[/tex]
Add this amount to the amount spent on popcorn
[tex]Amount\ Spent =\$6.25 + \$3.50[/tex]
[tex]Amount\ Spent =\$9.75[/tex]
To get the Change, we have to deduct the total amount spent from the amount given by mom
[tex]Change = \$20 - \$9.75[/tex]
[tex]Change = \$10.25[/tex]
Hence:
The change is $10.25

Jada fills the bathtub before taking a bath and then allows the water to drain when she is done. The graph below models the number of gallons of water, y, in the bathtub over time, t, in minutes. (look at graph)
Is the number of gallons of water in the bathtub a function of time?
A)Yes because each t value is paired with exactly one number of gallons.
B)Yes because the number of gallons is bounded between y = 0 and y = 36.
C)No because each number of gallons is paired with more than one t value.
D)No because from t = 5 to t = 20 the number of gallons of water is constant.
A.Yes because each t value is paired with exactly one number of gallons.
Step-by-step explanation:
Yes the number of gallons of water in the bathtub a function of time because each t value is paired with exactly one number of gallons.
Option A
Given :
The graph below models the number of gallons of water, y, in the bathtub over time, t, in minutes.
The number of gallons of water in bathtub depends on the time taken to fill or drain water
For each minutes in x there is one y value
There is no break in the graph . For each x value there is only one value
From this graph we can say that , for each t value (minutes) there is exactly one number of gallons (y value )
So, yes because each t value is paired with exactly one number of gallons.

What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
Let the first point be P ( -8 , 6 )
Let the second point be Q ( 4 , -4 )
Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values in the equation , we get
Slope m = ( -4 - 6 ) / ( 4 + 8 )
Slope m = -5/6
Now , the equation of line is y - y₁ = m ( x - x₁ )
y + 4 = ( -5/6 ) ( x - 4 )
Subtracting 4 on both sides , we get
y = -5 x/6 - 4/6
Now , the ordered pair be ( 6 , 0 )
5x + 6y + k=0, passes through ( -6 , 10 )
So , ( -30 + 60 + k = 0 )
k = -30
And , the line is 5x + 6y - 30 =0
So , the ordered pair ( 6 , 0) satisfies the condition of the equation
Hence , the ordered pair is ( 6 , 0 )

Which of the following is the graph of the solution set of t – 4 ≥ 4t + 8 or 3t >14 – 4t?
Answer:
Option (C)
Step-by-step explanation:
There are two inequalities,
t - 4 ≥ 4t + 8 ------(1)
3t > 14 - 4t ------(2)
By simplifying inequality (1),
t - 4 ≥ 4t + 8
t ≥ 4t + 8 + 4
t ≥ 4t + 12
t - 4t ≥ 12
-3t ≥ 12
t ≤ [tex]\frac{12}{(-3)}[/tex]
t ≤ -4
By solving inequality (2),
3t > 14 - 4t
3t + 4t > 14
7t > 14
t > [tex]\frac{14}{7}[/tex]
t > 2
From the given graphs, Option (C) will be the answer.

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
6-4*x-(6*x-8*x+4)=0
Pull out like factors :
2 - 2x = -2 • (x - 1)
Solve : -2 = 0
Solve : x-1 = 0

a reflection of the point across the x-axis
a reflection of the point across the y-axis

LuAnn is playing a math game. She chooses three cards. The value of each of her cards is shown. • First card: -12 • Second card: 3 • Third card: -5 What is the sum of the values of LuAnn's three cards?
The sum of all the cards of Luann is -14.
One of the four fundamental operations for arithmetic on integers, decimals, fractions, real and complex numbers, as well as in algebraic expressions or on structures related to them, including vector spaces, is sum (also known as addition).
The terms, addends, or summands collectively refer to the numbers or objects that need to be added in general addition; this nomenclature also applies to the summation of several terms. This should be distinguished from multiplied factors.Addition or sum follows the commutative , associative and distributive properties.The given numbers on the cards are given as - 12 , 3 and - 5 .
Therefore the addition or sum is equal to :
-12 + 3 + ( - 5 ) = - 17 + 3 = - 14
Hence the sum of all the cards in LuAnn's card games is -14.
