What is 2(n-1)+4n=2(3n-1)
Xelga [282]

Answer:

Infinite solutions

Step-by-step explanation:

<em><u>Distribute the 2 to (n - 1), and distribute the 2 to (3n - 1), like so:</u></em>

2(n - 1) + 4n = 2(3n - 1)

2n - 2 + 4n = 6n - 2

<em><u>Add like terms (2n and 4n):</u></em>

6n - 2 = 6n - 2

<em><u>Subtract 6n from both sides:</u></em>

-2 = -2

Since we ended up with the same term on both sides, we can't do anything else, meaning this equation has infinite solutions.

What is the mean for this set of data?
oee [108]
The mean is 14

add all the numbers up and divide the sum by 6 because that’s how many numbers you’re adding together.

12+10+14+18+14+16
= 84

84/6 = 14

The graph below shows the distance, y, in miles, of a bird from its nest for a certain amount of time, x, in minutes:
Montano1993 [528]

Answer:

0.2 miles per minute represents the speed of the bird and 3 miles represents the original distance of the bird from its nest.

Step-by-step explanation:

As there is no graph mentioned here but the information are quite sufficient to answer the question.

We have points (0,3), (5,4),(10,5)...

From these points we can find the slope of the line .

From point slope formula y-y_1=m(x-x_1)

And assigning (x,y) (0,3) and (x_1,y_1) (5,4)

m=\frac{y_1-y}{x_1-x} =\frac{4-3}{5-0} =\frac{1}{5}=0.2

This slope is also the speed of the bird which is 0.2\ miles\ per\ minute.

As by plugging the values of any coordinate point we can confirm this.

Lets put (10,5), y-axis is the distance so in 10 minutes the the distance covered by the bird must be equal to to y-axis value which is 5 miles.

y=0.2(x),y=0.2(10)=5\ miles

Now as in t=0 the bird has started from y-intercept value 3 so we can say that,the original distance of the bird from its nest is 3\ miles.

So the correct choices are:B and D

The birds speed is 0.2\ miles per minute and is 3\ miles away from its nest.
