Solve this equation
2 (c+8) = -12
Answer:
C= -14
Step-by-step explanation:
2(c+8)= -12 > divide both sides by 2
C+8= -6 > move c by itself
C= -6-8 > then subtract -6 and -8 and you will get -14

Find the domain and range of the relation of 6,5, -13, 1, -4,2, -5, 23, -10, -5
Answer:
[tex]Range = \{5,1,2,23,-5\}[/tex]
[tex]Domain = \{6,-13,-4,-5,-10\}[/tex]
Step-by-step explanation:
Given
[tex](6,5)\ (-13, 1)\ (-4,2)\ (-5, 23)\ (-10, -5)[/tex]
Required
Determine the domain and range
A relation has the following format:
[tex]\{(x_1,y_1),(x_2,y_2),(x_3,y_3),(x_4,y_4)........(x_n,y_n)\}[/tex]
The range of the relation are:
[tex]\{y_1,y_2,y_3,y_4........y_n\}[/tex]
While the domain are:
[tex]\{x_1,x_2,x_3,x_4........x_n\}[/tex]
Using this analysis, the domain of the relation is:
[tex]Domain = \{6,-13,-4,-5,-10\}[/tex]
and the Range is
[tex]Range = \{5,1,2,23,-5\}[/tex]

En una tienda se anuncia la rebaja de 20% en todos sus artículos. Rafael elije una camisa y al llegar a la caja le informan que esa camisa, por traer etiqueta roja, cuenta con un descuento adicional del 15%. Si Rafael pago $510.00, ¿cual era él precio de la camisa sin los descuentos?
9514 1404 393
Answer:
$750
Step-by-step explanation:
The 20% discount multiplies the price by (1 - 20%) = 0.80.
The 15% discount multiplies the price by (1 - 15%) = 0.85.
After applying the discounts to the initial price P, we have ...
P(0.80)(0.85) = $510
P = $510/(0.80·0.85) = $750
The price before discounts was $750.

I'm assuming the goal of this style of division is to divide by whole numbers instead of decimal numbers. In that case, you would need to move the decimal in the divisor and the dividend three places to the right.

Please check the explanation below.
Step-by-step explanation:
We know that a binary relation between two sets is termed as a function which associates every element of the first set to exactly one element of the second set.In other words, in order for relation to be a function, we must make sure there must be no repetition of 'x' coordinate values, as it would violate the fundamental definition of a function.
A) (2, 5), (5, 7), (7, 9)
Here, the x-coordinates are: 2, 5, and 7
At x = 2, y = 5
At x = 5, y = 7
At x = 7, y = 9
As there is no repetition of x-coordinates.Thus, the coordinate pairs (2, 5), (5, 7), (7, 9) represent the function.
B) (2, 3), (1, 4), (2, 8),(0, 1)
Here, the x-coordinates are: 2, 1, 2 and 0
At x = 2, y = 3
At x = 1, y = 4
At x = 2, y = 8
At x = 0, y = 1
Please observe that the x-coordinate values i.e. x=2 are repeated.
Thus, the coordinate pairs (2, 3), (1, 4), (2, 8),(0, 1) does not represent the function.
C) (4, 8), (5, 8), (6, 8)
Here, the x-coordinates are: 4,5 and 6
At x = 4, y = 8
At x = 5, y = 8
At x = 6, y = 8
As there is no repetition of x-coordinates.Thus, the coordinate pairs (4, 8), (5, 8), (6, 8) represent the function.
Please note that it does not matter if y-values are repeated. Just remember, we can not have repeated x-values.D) (-1, 4), (0, -1), (8, 3)
Here, the x-coordinates are: -1, 0, and 8
At x = -1, y = 4
At x = 0, y = -1
At x = 8, y = 3
As there is no repetition of x-coordinates.Thus, the coordinate pairs (-1, 4), (0, -1), (8, 3) represent the function.
E) (1, 8), (8, 1), (1, 3)
Here, the x-coordinates are: 1, 8, and 1
At x = 1, y = 8
At x = 8, y = 1
At x = 1, y = 3
Please observe that the x-coordinate values i.e. x=1 are repeated.
Thus, the coordinate pairs (1, 8), (8, 1), (1, 3) does not represent the function.
F) (9, 0), (9, 1), (9, 2), (9, 3)
Here, the x-coordinates are: 9, 9,9 and 9
At x = 9, y = 0
At x = 9, y = 1
At x = 9, y = 2
At x = 9, y = 3
Please observe that the x-coordinate values i.e. x=9are repeated.
Thus, the coordinate pairs (9, 0), (9, 1), (9, 2), (9, 3) does not represent the function.

Answer: to solve this you can make a proportion.
264 x
---- = ----
3 1
to solve, cross multiply and divde
264 times 1 is 1. 264 divided by 3 is 88. the unit rate is 88 beats in one minute
Step-by-step explanation:
Deron's heart beat rate per minute is 64 beats/min.
What is a unitary method?
A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.
Given, Deron recorded his heart rate as 204 beats in 3 minutes.
∴ How many times his heart beats in one minute or the unit rate in beats per minute can be obtained if we divide the total no. of beats by total no. of minutes which is,
= (204/3) beats per minute.
= 68 beats per minute.

3x + 2(4 + 6x) = 113
Explain what you did in each step of your solution.
Answer:
x = 7
Step-by-step explanation:
So first, multiply everything inside the ( ) by 2
So then, the equation will look like this: 3x + 8 + 12x = 113
Then, combine like terms, which leave the equation to look like this:
15x + 8 = 113
Then subtract 8 from both sides, leaving the equation like this : 15x = 105
Last step, divide both sides by 15, which leave you with x = 7
