Answer:

Hello, I would be glad to help you with this question.

The answer to this problem is C.

Step-by-step explanation:

The answer is C.

If you take a ratio and multiply it on each side, but it eventually is no longer applicable (not able) to multiply on either side, then it is not in fact a constant ratio. So if we are talking about a geometric sequence then the correct answer would be C. A geometric sequence, is a sequence that relates to a constant ratio. The only dividend (difference) between the two of them is that a geometric sequence is any constant ratio that can be multiplied by any odd number (any number that is not a multiple of 2). However, this rule does not apply whenever the number that is being multiplied is lower than 2. So, if we were to take f(n) (F being the left hand side of the ratio table. (n) being the right hand side) then divide it f (n-1) then you would be able to be multiplied by an even number which would then make a this equation a constant ration, and not a geometric sequence.

I hope this answer helped you!

How to solve this problem

Agata [3.3K]

So first, you have to get two of the same variables to cancel out. Let's do this for x. In order for the x's to cancel out, we could multiply the bottom problem by 2.
(2) 3x-6y=24
After multiplying all the numbers by 2, you get the equation 6x-12y=48
The set of equations is now
-6x+2y=12
6x-12y=48
Now you can add them. The x variables cancel out, so you are left with the y variable.
2y+-12y=-10y and 12+48=60
Then you would divide 60 by -10 to get y=-6.
You would plug the answer for y into one of the original equations, lets do the top one. -6x+2y=12 becomes -6x+2(-6)=12
You'd multiply the 2 and -6 to get -12 so the equation is
-6x-12=12
The negative 12 turn positive and you add to both sides to get the -6x alone.
-6x-12=12
+12=12
-6x=24
Then divide 24 by -6
X=4

(-4,-6) is your final answer.

Juan y Andrés son adultos mayores y maratonistas. Hoy participaron en la maratón internacional de los Andes.El locutor que cubre

Ira Lisetskai [31]

Answer:

3 hours 8 seconds

Step-by-step explanation:

Juan and Andrés are older adults and marathoners. Today they participated in the international marathon of the Andes. The announcer who covers this sporting event reported that Juan had finished the race with a time of 3¾ hours. Tijuanito the route in ⅔ of hours more than Andrés, how long did Andrés finish the marathon ?.

It is given that,

Juan had finished the race with a time of 3¾ hours.

He takes ⅔ of hours more than Andrés.

We need to find how long did Andrés finish the marathon.

Time taken by Juan = $\dfrac{15}{4}$ hours

Time taken by Tijuanito is $\dfrac{2}{3}$ hours more than Andrés.

So, Andrés finish the marathon $\dfrac{15}{4}-\dfrac{2}{3}=3.08\ \text{hours}$ before.

Write the slope-intercept form of the line through the points (4,-5) and (2, -1).

Leokris [45]

Slope intercept form is y=mx+b
to solve for m (slope) you must first subtract y2-y1 and x2-x1 then divide your answers

-1 - -5 = 4 (y)
2 - 4 = -2 (x)
4/-2 = -2

so your slope is -2

next plug in your slope and the point you choose

-1 = -2(2) + b
or
-5 = -2(5) +b

What is the value of the x variable in the solution to the following system of equations?

sveta [45]

There is no x value as there is no solution. I plugged into desmos cause it didnt make sense at first then it showed me that it has no solution.

3. A phone company set the following rate schedule for an m-minute

Leya [2.2K]

The obtained answers for the given piecewise function are:

(a) The cost of a call that is under six minutes is 0.70 (m < 6)

(b) The cost of a 14-minute call is 2.62 (m > 6; m is an integer)

<h3>What is a piecewise function?</h3>

A piecewise function is given by different functions at different intervals.

<h3>Calculation:</h3>

It is given that,

phone company set the following rate schedule for an m-minute call from any of its pay phones.

C(m) = 0. 70 when m ≤ 6

= 0.70 + 0.24(m - 6) when m > 6 and m is an integer

= 0.70 + 0.24([m - 6] + 1) when m > 6 and m is not an integer

(a) The cost of a call that is under six minutes:

Since m < 6, the cost is C(m) = 0.76

Thus, the cost of a call that is under six minutes is 0.76

(b) The cost of a 14-minute call:

Since 14 > 6, the cost is C(m) = 0.70 + 0.24(m - 6) when m > 6 and m is an integer.

C(14) = 0.70 + 0.24(14 - 6)

= 0.70 + 0.24(8)

= 0.70 + 1.92

= 2.62

Thus, the cost of a 14-minute call is 2.62.

(c) The cost of a 9 1/2 minute call:

9 1/2 = 19/2 = 9.5

Since 9.5 > 6, the cost is C(m) = 0.70 + 0.24([m - 6] + 1) when m > 6 and m is not an integer.

C(9.5) = 0.70 + 0.24([9.5 - 6] + 1)

= 0.70 + 0.24([3.5] + 1)

Since we know that if [x] is a function then its domain is R and the range is Z(integer)

So, [3.5] = 3(is an integer)

Then,

C(9.5) = 0.70 + 0.24(3 + 1)

= 0.70 + 0.96

= 1.66

Therefore, the cost of a 9 1/2 minute call is 1.66.
