Find the point of the intersection for the given systems y=x^2+1 and y=x+1
mario62 [17]

set them equal to each other

x²+1=x+1

minus 1 from both sides

x²=x

minus x both sides

x²-x=0

factor

x(x-1)=0

set each to 0

x=0


x-1=0

x=1


subsitute back to find y values

y=x+1, y=0+1, y=1, one point is (0,1)

y=x+1, y=1+1, y=2, another point is (1,2)


the 2 points of intersection are (0,1) and (1,2)

What measure of center best represents the data set?
inysia [295]
I feel like it would be mean or median, because there is no outlier, making it so that all of the numbers are closely put together.

Put the set into order.

25, 26, 27, 28, 29

So, we know that this is all in order, making it so that we know for sure that there is no outlier. 

If you find the mean, it'll represent the data nicely. 

We know that both the mean and median represent the data set nicely, because it just does. It's one of those things that are extremely painful and hard to fully explain and have someone understand, but don't worry, it makes sense.

So, it can't just be the mean only or the median only.

It also can't be the mode only, because THERE IS NO MODE! 

So, our final answer is mean or median :)

~Hope I helped!~

Write the first 4 terms of the sequence defined by the given rule f(n)=n2 -1
Softa [21]

Answer:

<h2>0, 3, 8, 15</h2>

Step-by-step explanation:

Substitute n = 1, n = 2, n = 3 and n = 4 to the equation f(n) = n² - 1:

f(1) = 1² - 1 = 1 - 1 = 0

f(2) = 2² - 1 = 4 - 1 = 3

f(3) = 3² - 1 = 9 - 1 = 8

f(4) = 4² - 1 = 16 - 1 = 15
