To find the number of different pairs that can be made with four colors, we use the combinations formula C(4, 2), which calculates to 6. Thus, there are 6 different color pairs that can be made with red, blue, green, and purple.
To determine how many different pairs can be made with four colors: red, blue, green, purple, we use the concept of combinations from mathematics. A combination is a selection of items where the order does not matter. In this case, we are selecting two colors from the four available to form a pair.
To calculate the number of combinations without repetition, we can use the combination formula which is [tex]C(n, k) = \frac{n! }{ (k!(n - k)!)}[/tex], where n is the total number of items to choose from, k is the number of items to choose, and '!' represents the factorial of a number. For this scenario, n = 4 (four colors) and k = 2 (since we are forming pairs).
So, the number of combinations is C(4, 2) = [tex]\frac{4! }{2!(4 - 2)!} = \frac{4 \times 3 \times 2 \times 1 }{ 2 \times 1 \times 2 \times 1}[/tex] = 6. Therefore, there are 6 different color pairs that can be made with the colors red, blue, green, and purple.

thank you!
answer Y=1 over 4 and Y= 2 over 3 that is your answer and these are the steps I'm going to put a image hope this is useful to u and have a beuty day
Answer:
f(y) = 12y^2 -5y -2 = 0
a = 12 b =-5 c=-2
Using quadratic formula:
y = [-b +-sq root (b^2 -4ac)] / 2 a
y = [--5 +-sq root (25 -4*12*-2)] / 24
y = [5 +- sq root (25 + 96) ] / 24
y = [5 +- sq root (121) ] / 24
y = [5 + 11] / 24
y1 = (2/3) = .66666666666
y2 = 5 -11 / 24
y2 = -(1/4) = -.25

Step-by-step explanation:
A group of students are planning a mural at a wall the rectangular wall has dimensions of (6x+7) by (8x+5) and they are planning the mural to be (x+4) by(2x+5) what is the area of the remaining wall after the mural has been Painted
Answer: [tex]46x^2+73x+15[/tex]
Step-by-step explanation:
The area of a rectangle can be calculated with the formula:
[tex]A=lw[/tex]
l: the length of the rectangle.
w: the width of the rectangle.
The area of the remaning wall after the mural has been painted, will be the difference of the area of the wall and the area of the mural.
Knowing that the dimensions of the wall are [tex](6x+7)[/tex] by [tex](8x+5)[/tex], its area is:
[tex]A_w=(6x+7)(8x+5)\\\\A_w=48x^2+30x+56x+35\\\\A_w=48x^2+86x+35[/tex]
As they are planning that the dimensions of the mural be [tex](x+4)[/tex] by [tex](2x+5)[/tex], its area is:
[tex]A_m=(x+4)(2x+5)\\\\A_m=2x^2+5x+8x+20\\\\A_m=2x^2+13x+20[/tex]
Then the area of the remaining wall after the mural has been painted is:
[tex]A_{(remaining)}=A_w-A_m\\\\A_{(remaining)}=48x^2+86x+35-(2x^2+13x+20)\\\\A_{(remaining)}=48x^2+86x+35-2x^2-13x-20\\\\A_{(remaining)}=46x^2+73x+15[/tex]

Describe in words how to obtain the graph of f(t) = sin(5t + 20) − 7 from the graph of y = sin(5t).
Answer: f(t) is shifted 20 units to the left and 7 units down
Step-by-step explanation:
The general form of a sin function is: y = A sin (Bx - C) + D
A is the vertical stretch (amplitude)B is the horizontal compressionC is the horizontal shift (left or right)D is the vertical shift (up or down)y = sin (5t)
f(t) = sin (5t + 20) -7
the C-value is -20 --> shifts 20 units to the leftthe D value is -7 --> shifts 7 units downTalia uses 10 strawberries and 4 oranges to make 8 servings of fruit salad. how many oranges and strawberries does talia need to make 12 servings?

help please! which choice represents the fraction below as a single exponential expression?
Answer:
B
Step-by-step explanation:
use the exponent rule of division: you just subtract the exponents if the base is the same, so 4-8=-4
The fraction with a numerator of 3.74 x 10⁻¹⁶ and a denominator of 10⁻³⁰ represented as a single exponential expression is 3.74 x 10¹⁴, obtained by dividing the digit terms and subtracting the exponents.
Explanation:To represent the fraction as a single exponential expression, you follow the division of exponentials rule, which involves dividing the digit terms and subtracting the exponents of the exponential terms. Given the fraction with a numerator of 3.74 x 10-16 and a denominator of 10-30, you would divide 3.74 (the digit term of the numerator) by 1 (the implied digit term of the denominator) which is just 3.74, and subtract the exponents (-16 - (-30)) which equals 14. Therefore, the fraction as a single exponential expression is 3.74 x 1014.

How can x + 3 = −2x + 5 be set up as a system of equations?
Answer:
y = x+3; y = -2x +5
Step-by-step explanation:
x + 3 = -2x + 5
Let y = x + 3 = -2x + 5
If a = b = c then a=b and a=c
we can write the equation as
y = x + 3 and y = -2x + 5
Thus, this is the system of equations
y = x + 3
y = -2x + 5
Answer:
y = x + 3 and y = -2x + 5
Step-by-step explanation:
If we consider one set of equation as:
[tex] y = x + 3 [/tex]
and the other set of equation as:
[tex] y = - 2 x + 5 [/tex]
Since the left hand side for both these equations is same, therefore we can equate the right hand side and write it as:
[tex] x + 3 = - 2 x + 5 [/tex]

Rebecca has a credit line of $6,500. She had a previous balance of $398.64 and made a payment of $250. The total of her purchases is $1,257.99. What is Rebecca's available credit?
Answer:
$5093.37
Step-by-step explanation:
To get Rebecca's available credit we need to take all of her payments and purchases and previous balance.
Previous balance = $398.64
Purchases = $1,257.99
Payment = $250
Credit Line = $6,500
Now first we add together her purchases and previous balance.
398.64 + 1,257.99
This will give us:
$1,656.63 Total deductions.
Now we subtract that to her credit line.
$6500.00 - $1656.63
$4843.37
Now we take her payment and add it to her credit line.
$4843.37 + $250
$5093.37
So Rebecca's available credit is $5093.37.

111 = 14g what is g??
Answer:
the answer to this is 7.9 or 7 13/14
Step-by-step explanation:
1. Divide both sides by 14
111/14 = 14g/14
2. Simplify
g = 7 13/14
Final answer:
The variable 'g' in the equation 111 = 14g is found by dividing 111 by 14, resulting in approximately 7.929 (rounded to 4 significant figures).
Explanation:
The equation given is 111 = 14g, which seems to be a simple algebra equation where you are solving for the variable g. To find g, you would divide both sides of the equation by 14 to isolate g.
This calculation yields: g = 111 / 14, which equals 7.92857142857. However, this number might need to be rounded depending on the context or instructions for significant figures. If the problem instructions mentioned 4 sig figs, the answer would be rounded to 7.929.
Two planes left simultaneously from the same airport and headed in the same direction towards another airport 1800 km away. The speed of one of the planes was 100 km/hour slower than the speed of the other plane, and so it arrived at its destination 36 minutes after the faster plane. Find the speeds of both planes.
Answer:
Faster plane --> 600km/hr
Slower Plane --> 500km/hr
Step-by-step explanation:
Use inequality: 1800/r = 1800/(r-100) + 3/5 and solve to get r = 600, so the plane which is r -100 is 500 km/hr.

The total cost for 12 months of this service for n cars is given by the expression below.
568n + 230
Answer:
Option C
Step-by-step explanation:
There are several types of costs in this problem:
* Unique costs
* Costs that depend on the number of cars
* Costs that depend on the number of months
* Costs that depend on the number of months and the number of cars.
The costs that depend on the number of cars represent the coefficient of the variable n.
The costs that do not depend on the number of cars represent the constant value of the equation.
Then, to solve this problem you must identify the costs that do not depend on the number of cars.
These costs are:
* Membership Fee: $ 50 (one-time cost)
* Pull Pressure Check Cost: $ 15 per month
[tex]\$50 + \$15(12\ month) = \$230[/tex]

Answer:
The answer is C because when you substituted the coordinate pairs into the equation, both sides are equal which tells you that they're a solution to the equation.
Explanation:
All you do is substitute. (x,y)
A:
Substitute
1 = 4(2) - 7
Multiply the number inside the parentheses by the outside number.
1 = 8 - 7
Subtract to get your solution.
1 = 1
Both sides equal to each other so this means that this is a solution to the equation.
B:
Substitute
9 = 4(4) - 7
Multiply the number inside the parentheses by the outside number.
9 = 16 - 7
Subtract to get your solution.
9 = 9
Both sides equal to each other so this means that this is also a solution to the equation.
D:
Both ordered pair is a solution to the equation.

Passing through (negative 2,4) and (3,4)
Answer:
y = 4
or
y - 4 = 0(x - 3)
Step-by-step explanation:
The points (-2,4) and (3,4) have the same y-value. Because of this, the slope of the line will be 0 and the line will be horizontal. This means the line will have the equation y = b where b is the y-coordinate. The equation of the line is
y = 4.
In point slope form, the equation will have m = 0.
y - 4 = 0(x -3)
