PLZZ CAN SOMEONE CHECK MY ANSWERS !!!

Mathematics
1 answer:
larisa86 [58]3 years ago
8 0

Answer:

(1,0)

(5,24)

(-2,3)

Step-by-step explanation:

So we want y=x^2-1 per point.

Let's check them.

(0,1)? Plug in 0 for x and see what y is:

y=0^2-1

y=0-1

y=-1 which is not 1.

(1,0)? Plug in 1 for x and see what y is:

y=1^2-1

y=1-1

y=0 which is what we have for y.

(3,5)? Plug in 3 for x and see what y is:

y=3^2-1

y=9-1

y=8 which is not 5.

(5,24)? Plug in 5 for x and see what y is:

y=5^2-1

y=25-1

y=24 which is what we have for y.

(-2,3)? Plug in -2 for x and see what y is:

y=(-2)^2-1

y=4-1

y=3 which is what y is.

(-4,-17)? Plug in -4 for x and see what y is:

y=(-4)^2-1

y=16-1

y=15 which is not -17.

PLS HELP WILL MARK BRAINLIEST The average of eight consecutive odd integers is 48. What is the range of these eight numbers?
natima [27]

Answer:

Step-by-step explanation:

2x - 7 + 2x - 5 + 2x - 3 + 2x - 1 + 2x + 3 + 2x + 5 + 2x + 7   Combine like terms

16x / 8  = 48

2x = 48

x = 24

The range is defined as the largest number - the smallest number

The range is between 2x - 7 and 2x + 7

x = 24

The smallest number is 48 - 7 = 41

The largest number is 48 + 7 = 55

The range = 55 - 41 = 14

Why was the 2 in front of the x needed? It was to make sure that I could create an odd number.

Why did I subtract an odd number? That was to make sure that I could create odd numbers.

Why did I start with 2x - 7 and end up 8 terms later at 2x + 7?

So the numbers would cancel and I'd only be left with x's.

Find the distance between the points J( – 8,0) and K(1, 4).
Ksenya-84 [330]

Answer:

The answer is

\sqrt{97}  \:  \: units

Step-by-step explanation:

The distance between two points can be found by using the formula

d =   \sqrt{ ({x1 - x2})^{2}  +  ({y1 - y2})^{2} }

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

J( – 8,0) and K(1, 4)

The distance between them is

|JK|  =  \sqrt{ ({ -  8 - 1})^{2} +  ({0 - 4})^{2}  }  \\  =  \sqrt{ ({ - 9})^{2} + ( { - 4})^{2}  }  \\  =  \sqrt{81 + 16}  \\

We have the final answer as

\sqrt{97}  \:  \:  \: units

Hope this helps you
