Gabriel is deciding between two different movie streaming sites to subscribe to. Plan 1 cost $22 per month plus $1 per movie watched. Plan 2 cost $14 per month plus $3 per movie watched. Create a system of equations to represent this situation. Explains how many movies, x, would cause the two plans to have an equal monthly cost.
The number of movies that would make the monthly cost equal is 4.
What is the number of movies when the plans' cost would be equal?The total monthly cost is a function of the cost per month, total movies watched and the cost per movie.
The equations that represent the total cost of using the streaming sites would be in the form:
Total cost = cost per month + (number of movies watched x cost per movie)
Plan 1: $22 + ($x)
Plan 2: $14 + (3x)
When both plans have the same monthly cost, the two above equations would be equal
$22 + x =$14 + 3x
In order to determine the value of x, take the following steps:
Combine similar terms: $22 - $14 = 3x -x
Add similar terms together: $8 = 2x
Divide both sides of the equation by 2: $8 /$ 2 = x
x = 4

Graph y=0.2x use the graph to find the value of x when y=-2,0,2
By graphing the equation y = 0.2x, we find that x is equal to -10 when y is -2, x is equal to 0 when y is 0, and x is equal to 10 when y is 2.
To graph the equation y = 0.2x, we can plot a few points and then connect them to create the line.
Let's calculate the corresponding values of x when y takes on the values of -2, 0, and 2:
When y = -2:
-2 = 0.2x
x = -2 / 0.2
x = -10
When y = 0:
0 = 0.2x
x = 0 / 0.2
x = 0
When y = 2:
2 = 0.2x
x = 2 / 0.2
x = 10
Using these values, we can plot the points (-10, -2), (0, 0), and (10, 2) on the coordinate plane. Drawing a line passing through these points, we obtain the graph of the equation y = 0.2x.
The graph will be a straight line that passes through the points (-10, -2), (0, 0), and (10, 2). The line will have a positive slope, indicating that as x increases, y increases at a slower rate.
The graph visually represents the relationship between x and y according to the equation y = 0.2x. It shows that for every increase of 1 unit in x, y increases by 0.2 units.

Prove by C/D formulas that cos 6°×cos66°×cos42°×cos78° = 1/16
Answer:
True.
Step-by-step explanation:
(LHS) cos 6∘ cos 42∘ cos 66∘ cos 78∘
1/4 [cos(66∘+6∘) = cos(66∘-6∘)] • [cos(78∘+42∘)+cos(78∘-42∘)]
= 1/4(sin18∘+12)(-12+cos36∘)
[∵cos72∘ = cos(90∘−18∘) = sin18∘]
1/4[(5-√-1)/4+1/2][−1/2+(5-√+1)/4]
[∵sin(18∘ = (5-√-1)/4, and, cos 36∘ = (5-√+1)/4]
1/4(5-√+1)/4(5-√-1)/4 = (5-1)/64

What is the probability that a hand of five cards chosen at random and without replacement from a standard 52 card deck will have a king of spades, exactly one other king, and exactly two queens?
The probability that a hand of five cards chosen at random and without replacement from a standard 52 card deck will have a king of spades, exactly one other king, and exactly two queens = 0.000332
A deck of cards consist of 52 cards in which each 13 cards are from 4 suits: Spades, Hearts, Diamonds and Clubs.
Each suit consist of cards Ace, King, Queen, Jack and other 9 cards.
So in 52 cards there is 4 kings and 4 queens each.
Five cards are selected at random and without replacement.
Five cards from a 52 deck cards can be chosen in 52C5 ways.
A spade king can be chosen in 1C1 way. [ Since there is only one spade king]
Exactly one other king can be chosen in 3C1 ways. [Since now only 3 kings are remaining after choosing 1 spade king]
Exactly 2 queens can be chosen in 4C2 ways.
Now 4 cards are selected out of 5. The remaining 1 card is chosen out in 48C1 ways.
So the probability that the five cards chosen will have a king of spades, exactly one other king, and exactly two queens
= (1C1 x 3C1 x 4C2 x 48C1) /52C5 = 18/54145 =0.000332

Midpoint: Length: Midpoint: Length:
The midpoint and length of the points J(4,3) and K(2,-3) is calculated as (1,0) and 40.
The midpoint and length of the points L(-4,5) and N(5,-3) is calculated as (-12,1) and 145.
Given : The endpoints J(4,3) and K(2,-3) and L(-4,5) and N(5,-3)
We need to find the midpoint and length of these endpoints.
The formula for midpoint is x1+x22, y1+y22
From the first endpoints, x1=4 , y1=3 , x2=2 , y2=-3
4+22, 3-32 => (22,02) => (1,0)
So, the midpoint for the endpoints is (1,0)
The formula to find the length is (x2-x1)2+(y2-y1)2
From the first endpoints , the length becomes
(2-4)2+((-3)-3)2=> (-2)2+(-6)2 => 4+36 => 40
The formula for midpoint is x1+x22, y1+y22
From the first endpoints, x1=-4 , y1=5 , x2=5 , y2=-3
-4+52, 5-32 => (-12,22) => (-12,1)
So, the midpoint for the endpoints is (-12,1)
The formula to find the length is (x2-x1)2+(y2-y1)2
From the first endpoints , the length becomes
(5+4)2+((-3)-5)2=> (9)2+(-8)2 => 81+64 => 145
Hence, the midpoint and the length from the endpoints is calculated and determined.

9) (x, RS, MN) = (8, 41, 41)
11) (AB, BC, AC) = (42, 42, 84)
What are the values of the variable x and the lengths of the line segments?
In this question we have three cases of colinear line segments, each of them can be solved by using definitions from Euclidean geometry and algebraic handling:
Case 7 - TU = 2 · x, UB = 3 · x + 1, TB = 21
TB = TU + UB
21 = 2 · x + 3 · x + 1
21 = 5 · x + 1
5 · x = 20
x = 4
Then, the lengths of each line segment are:
TB = 21
TU = 2 · 4
TU = 8
UB = 3 · 4 + 1
UB = 13
The solutions are (x, TU, TB) = (4, 8, 13).
Case 9 - RS = 3 · x + 17, MN = 7 · x - 15
RS = MN
3 · x + 17 = 7 · x - 15
4 · x = 32
x = 8
And the lengths of each line segment are:
RS = MN = 41
The solutions are (x, RS, MN) = (8, 41, 41).
Case 11 - AB = 2 · x - 8, BC = x + 17
AB + BC = AC
AB = BC
2 · x - 8 = x + 17
x = 25
And the lengths of each line segment are:
AB = 2 · 25 - 8
AB = 42
BC = AB
BC = 42
AC = 42 + 42
AC = 84
The solutions are (AB, BC, AC) = (42, 42, 84).

Answer:
(i) 2² · 3 · 7
(ii) 3024
(iii) k = 16
(iv) 12 cm
Step-by-step explanation:
Part (i)The first few prime numbers are: 2, 3, 5, 7, 11, 13, 17, ...
To find which prime numbers multiply together to make 84, start by dividing 84 by the first prime number, 2:
⇒ 84 ÷ 2 = 42
As 42 is not a prime number, we need to divide again:
⇒ 42 ÷ 2 = 21
As 21 is not a prime number, we need to divide again.
21 is not divisible by 2, so let's try dividing by the next prime number, 3:
⇒ 21 ÷ 3 = 7
As 7 is a prime number, we can stop.
Therefore, 84 is the product of:
⇒ 84 = 2 · 2 · 3 · 7
As 2 appears two times, we can write this using exponents:
⇒ 84 = 2² · 3 · 7
Part (ii)Lowest Common Multiple (LCM): The lowest multiple shared by two or more numbers.
Prime Factors Method of finding LCM
Step 1
Find the prime factorization of each number.
From part (i): 84 = 2² · 3 · 7
Given in part (ii): 432 = 2⁴ · 3³
Step 2
Write each number as a product of primes, matching primes vertically where possible:
[tex]\begin{array}{ r c c c c c c c ccccccccc}84&=& 2 & \cdot & 2 & \cdot & & & & & 3& \cdot & & & && 7\\\\432 &=& 2 & \cdot & 2 &\cdot & 2& \cdot & 2& \cdot & 3& \cdot & 3& \cdot & 3\\\\\cline{1-17} \\\sf LCM & = & 2 & \cdot & 2 &\cdot & 2& \cdot & 2& \cdot & 3& \cdot & 3& \cdot & 3 &\cdot & 7\end{array}[/tex]
Step 3
Bring down the primes in each column then multiply the factors to get the LCM:
⇒ LCM = 2 · 2 · 2 · 2 · 3 · 3 · 3 · 7
⇒ LCM = 2⁴ · 3³ · 7
⇒ LCM = 3024
Part (iii)From part (ii) we know that the prime factorization of 432 is:
432 = 2⁴ · 3³
A perfect cube is a number multiplied by itself three times.
One of the factors of 432 is a perfect cube → 3³.
Therefore,
[tex]\begin{aligned}432 & = 2^4 \cdot 3^3\\\\\implies \dfrac{432}{2^4} & = 3^3\\\\\dfrac{432}{16} & = 3^3\end{aligned}[/tex]
So we need to divide 432 by 2⁴ to get the perfect cube 3³.
Therefore,
⇒ k = 2⁴
⇒ k = 2 · 2 · 2 · 2
⇒ k = 16
Part (iv)To find the largest possible length of the side of the square, we need to find the greatest common factor of 432 and 84.
Prime Factors Method of finding GCF
Step 1
Find the prime factorization of each number.
From part (i): 84 = 2² · 3 · 7
Given in part (ii): 432 = 2⁴ · 3³
Step 2
Write each number as a product of primes, matching primes vertically where possible:
[tex]\begin{array}{ r c c c c c c c ccccccccc}84&=& 2 & \cdot & 2 & \cdot & & & & & 3& \cdot & & & && 7\\\\432 &=& 2 & \cdot & 2 &\cdot & 2& \cdot & 2& \cdot & 3& \cdot & 3& \cdot & 3\\\\\cline{1-17} \\\sf GCF & = & 2 & \cdot & 2 & \cdot & & & & & 3& & & & && \end{array}[/tex]
Step 3
Bring down the primes in the columns where both numbers have the factor, then multiply the factors to get the GCF:
⇒ GCF = 2 · 2 · 3
⇒ GCF = 12
Therefore, the largest possible length of the side of the square is 12 cm.
