Formule una propiedad algebraica basica del sistema de numeros reales para justificar cada uno de los siguientes enunciados, donde Y y Z representan numeros reales. a) (y + 2)z+3=(yz+2z)+3 b) (4+7)y=y(4+7) C) (1+4)+3=4+(1+3)
Answer:
Nose :>
Step-by-step explanation:
.
The algebraic properties that can be applied in this case are: distributive property, commutative property, associative property.
What properties can we apply in this situation?a) Distributive Property: (y + 2)z + 3 = yz + 2z + 3. The distributive property establishes that multiplication is distributed over addition or subtraction, allowing us to simplify the original expression by adding the product of y and z to 2z and then adding 3.b) Commutative property: 4y + 7y = y(4 + 7). The Commutative Property of Multiplication states that the order of the factors does not affect the result. Here, 4y and 7y can be rearranged as y(4) and y(7) respectively, keeping the same result.c) Associative Property: (1 + 4) + 3 = 4 + (1 + 3). The Associative Property of Addition states that numbers can be grouped in different ways without changing the sum total. Both sides of the equation group the numbers the same way.Note: The question is in Spanish. Here is the question in English:
Formulate a basic algebraic property of the real number system to justify each of the following statements, where Y and Z represent real numbers. a) (y + 2)z + 3 = (yz + 2z) + 3
b) (4 + 7)y = y (4 + 7)
c) (1 + 4) + 3 = 4 + (1 + 3)

Solve 48-5i=-4x+10yi
Answer:
Step-by-step explanation:
Suppose we decide to solve for y first. y will then be in terms of x AND a real and an imaginary term:
48-5i=-4x+10yi
The goal here is to solve for y. Adding 4x to both sides yields
48 - 5i + 4x = 10yi
and then we divide both sides by 10i to isolate the variable y:
48 - 5i + 4x
----------------- = y This result is "y in terms of the constant 48, the
10i imaginary terms 5i and 10i, and the expression 4x.
We solve the original equation for x in a similar manner:
48-5i=-4x+10yi becomes 48 - 5i - 10yi = -4x, so that:
-(48 - 5i - 10yi)
x = ------------------------

Find the zeros of the following function f (x) = 2x^2 – x – 10
Step-by-step explanation:
the formula to find the x values to deliver y=0 results of a squared equation is
x = (-b ± sqrt(b² - 4ac))/(2a)
a, b, c are the constant factors in the 3 terms of a squared equation.
here in our example of 2x² - x - 10
a = 2
b = -1
c = -10
x = (1 ± sqrt(1² - 4×2×-10))/(2×2) =
= (1 ± sqrt(1 + 80))/4 = (1 ± sqrt(81))/4 =
= (1 ± 9)/4
x1 = (1 + 9)/4 = 10/4 = 2 2/4 = 2 1/2 = 2.5
x2 = (1 - 9)/4 = -8/4 = -2

Answer is 68.9 m/min.
Step-by-step explanation :-Let's convert the units. To do this, we need to cancel the original units to get the units we want. We achieve this the following way :-
[tex]2.57 \frac{mi}{hr} \times \frac{1069.34 \: m}{1 \: mi} \times \frac{1 \: hr}{60 \: min} [/tex]
[tex] =>68.9 \: \frac{m}{min} [/tex]
Therefore, 2.57 mi/hr is the same as 68.9 m/min .

Step-by-step explanation:
what number has 62 ones, 20 ten thousands, and 300 tens
Hope it helped you brainiest plz and thank you have a great day!!!
The number for the given statement is 203,062.
We need to find what number has 62 ones, 20 ten thousand, and 300 tens.
How to write the number into a word statement?In general, use words to express numbers zero through nine, and use numerals to express numbers 10 and above. However, there are exceptions to this general guideline for number usage.
Now, 62 ones=62×1=62
20 ten thousand=20×10,000=200,000
300 tens=300×10=3000
Now add all these numbers.
That is, 200,000+3000+62
=203,062
Therefore, the number for the given statement is 203,062.

here m = 3/4
(x1,y1) = 3,-2
Substitute all the values in Formula
[tex]y + 2 = \frac{3}{4} (x - 3) \\ y + 2 = \frac{3}{4} x - \frac{9}{4} \\ y = \frac{3}{4} x - \frac{9}{4} - 2 \\ = \frac{3}{4} x - \frac{17}{4} \\ 4y = 3x - 17 \\ - 3x + 4y = - 17[/tex]
multiply by 4 on both sides
[tex]4y = 3x - 17 \\ - 3x + 4y = - 17[/tex]
Freeman High School's drill team will be attending the national competition and needs to raise $1,600. To raise money for the trip, the girls are selling tickets to a luncheon. Tickets are $8 for students and $10 for adults. The equation 8x+10y=1600, where x represents the number of student tickets sold and y represents the number of adult tickets sold, can be used to represent this situation. The graph of this equation is shown below.
The equation that can be used to represent this situation is 8x + 10y = 1600
Let x represent the number of student tickets sold and y represents the number of adult tickets sold.
Since students ticket cost $8 and adult tickets cost $10, and the total ticket sold was $1600, hence this can be represented by the equation:
8x + 10y = 1600
Therefore the graph of the above equation is attached

Answer:Bb 12. Cyborg 12
Step-by-step explanation:
Right for my test
The required number of items purchased by the beast boy is 4 and by Cyborg is 2.5.
Given that,
At a bargain store beast boy bought 5 items that each cost the same amount. Cyborg bought 8 items that each cost the same amount, but each was $1.50 less than the items beast boy bought. Both beast boy and Cyborg paid the same amount of money.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Let the cost of the item bought by the beast boy is x, and the item bought by the Cyborg be y,
According to the question,
5x = 8y
x = 8/5y - - - - - - -(1)
y = x - 1.50 - - - - - -(2)
Substitute the value of equation 1 to equation 2
y = 8/5y - 1.50
5y = 8y - 7.50
7.50 = 3y
y = 2.5
Now, put y in equation 1
x = 8 / 5 × 2.5
x = 8 × 0.5
x = 4
Now, the costs,
5x = 4 × 5 = $20
8y = 8 × 2.5 = $20
Thus, the required number of items purchased by the beast boy is 4 and by Cyborg is 2.5.
