La persona de finanzas utilizó la función "y"=15000-3000x para representar gráficamente depreciación que tipo de variación representa?
............ 1..1.1.1..1.1.
The graph of the function y = 15000 - 3000x represents linear regression.
What is the general equation of a Straight line?
The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.
We have a finance person who used the function y = 15000 - 3000x to graph depreciation.
We have the following of depreciation -
y = 15000 - 3000x
The graph of the function y = 15000 - 3000x will have a negative slope of -3000. The line makes an obtuse angle with the +x - axis. This type of variation is called linear regression.
Therefore, the graph of the function y = 15000 - 3000x represents linear regression.

X, Y and Z are partners in a firm in the ratio of 1/2 :1/3:1/6
Y retires from business and
X and Z purchase his share of profit in the ratio of 3:2. Find out new ratio
Answer:
6:2
Step-by-step explanation:
X share from old ratio is 1/2
Y share from old ratio is 1/3
Z share from old ratio is 1/6
Now, we are told Y retires and that X and Z purchase his shares.
Thus;
Amount X took from Y = 1/2 × 1/3 = 1/6
Amount Z took from Y = 1/6 × 1/3 = 1/18
Thus, new share of X is now; 1/6 + 1/2 = 2/3
New share of Z is now; 1/18 + 1/6 = 4/18 = 2/9
Ratio is now X:Z = 2/3 : 2/9 = 6:2

divide 1/2 and 3/4 and it can not be a mixed number.
Answer:
Many options - 4/6 or 2/3 or 0.66
Step-by-step explanation:
When dividing fractions, we use KCF (keep, change, flip) so our new equation is 1/2 x 4/3. Just multiply! Your answer should be 4/6, and if it needs to be simplified, the answer is 2/3. The answer as a decimal is 0.66 !
Answer:You first would do 1/2 x 4/3 becuase when dividing numbers you use the keep change and flip method. So 1/2 you keep, you change the division sign into a multiplication sign and then 3/4 you flip into 4/3. After that you should have 1/2 x 4/3 and that gets you 4/6. So 4/6 would be your answer but simplified it would be 2/3. - Hope this helps!

Answer:
Approx : 14.0294372515
Step-by-step explanation:
There are 2 congruent right triangles in this trapezoid. The hypotenuse and adjacent side lengths are 19 and 17 respectively. Using the Pythagorean Theorem, 19^2-17^2 is 72. The square root of 72 is approximately 8.48528137424. That is the length of the portions on the bottom that don't include the length x. 8.48528137424*2 is approximately 16.9705627485. 31-16.9705627485 gives you the length of the side x.
Divide 4500 into two parts such that 5% of the first part is equal to 10% of the second part
Answer:

given
5% of x = 10% of y

x=2y
2y+y=4500
3y=4500
y=1500
x+1500=4500
x=4500−1500
x=3000
hence the 4500 is been divided into
two parts of 1500 and 3000.

What is the value of y ?
Answer:
y=4
Step-by-step explanation:
because this is an equilateral triangle, this means that all the size of the lengths is equal this means that,
2y+5 = 4y-3
(add 3 for both sides)
2y+8 = 4y
(subtract 2y for both sides)
8 = 2y
(divide by 2 for both sides)
4 = y
so,
y=4

What is the perimeter of JKL?
Answer:
The perimeter of JKL is 60 units.
Step-by-step explanation:
The two tangents of a circle formed by a vertex outside the circle will always be the same distance, this means that JA = JB = 13, LA = LC = 7, and KB = KC = 10. JL = JA + LA = 20, KL = LC + KC = 17, and JK = JB + KB = 23. So the perimeter of triangle JKL is 20 + 17 + 23 = 60 units.

Answer:
x = 874
Step-by-step explanation
Set up your equation like this: Part/whole = percent/100
Assign the variable x to the unknown part of the equation and add in the known numbers:
So in this situation it would be: x/920 = 95/100
Solve for x:
100 times X = 920 times 95. (cross multiply)
That leaves you with 100x = 87,400
Divide both sides by 100:
x = 874

Answer:
c = 4
Step-by-step explanation:
The equation has a constant on one side of the equal sign, and a variable term on the other side. Solve this by dividing both sides of the equation by the coefficient of the variable.
[tex]2800=700c \qquad\text{given}\\\\ \dfrac{2800}{700}=\dfrac{700c}{700}\qquad\text{divide both sides by 700}\\\\4 = c \qquad\text{simplify}[/tex]

A dozen donuts cost $2.99. To the nearest cent, what is the cost of 1 donut?
Answer:
that person is correct, each donut is only .25 cents because every 4 donuts are $1, multiply 4 by 3 and you get 12, 12=dozen. Since the total price is $3 it makes sense that each donut in .25 cents and every 4 donuts $1
HOPE THIS HELPS AND HOPE THIS MAKES SENSE!!!!!!!
If a dozen donuts cost $2.99 then the cost of one donut is approximately $0.25.
What is Division?A division is a process of splitting a specific amount into equal parts.
Given that a dozen donuts cost $2.99.
We have to find the cost of 1 donut
As there are 12 donuts in a dozen, so to find the cost of one donut.
1 dozen donuts = 12 donuts.
One dozen donuts equal to twelve donuts.
To find the cost of 1 donut we need to divide the cost of a dozen by 12, because we are splitting the cost two point nine nine among twelve donuts.
$2.99 ÷ 12
Two point nine nine is divided with twelve we get zero point two five.
= $0.25
Therefore, the cost of one donut is approximately $0.25 to the nearest cent.

5 subtracted from 3 times a number x gives 7.
Answer:
3x-5=7
3x=7+5
x=12/3
x = 4
Answer:
Step-by-step explanation:
3 times a number x: 3*x = 3x
5 subtracted from 3x = 3x - 5
Equation: 3x - 5 = 7
Solution:
Add 5 to both sides
3x - 5 + 5 = 7 + 5
3x = 12
Divide both sides by 3
3x/3 = 12/3
x = 4
