Solve the system below.

1 answer:

6 0

To solve this system, let y = x^2 - 4 = -4. Then y = x^2. This is true for all x. There is no single numerical solution. y = x^2 is a function with infinitely many inputs/outputs.

Clint is in study hall reading The hunger games. After 20 minutes, he is on page 151. After 45 minutes, he is on page 181. How m

alexdok [17]

Answer:

The number of pages had Clint read prior to study hall were 127 pages.

Step-by-step explanation:

Given:

Clint after 20 minutes is on page 151.

And, after 45 minutes he is on page 181.

Now, to find the pages Clint read prior to study hall.

The time difference = 45 minutes - 20 minutes.

= 25 minutes.

Difference between the pages = 181 - 151

= 30 pages.

If Clint is reading each page at same speed.

Then, in 25 minutes he can read = 30 pages.

So, in 1 minute he can read = 30 ÷ 25 = 1.2 pages.

Thus, in 20 minutes he can read $=1.2\times 20$

$=24 pages.$

Now, number of pages Clint had read prior to study hall = 151 - 24

= 127 pages.

Therefore, the number of pages had Clint read prior to study hall were 127 pages.

V(x + 9)2 = + 25 If x + 9 = 5, then x = If x + 9 = -5, then x =

ipn [44]

Answer:

x = -4, v = 2.5

x = -14, v = -2.5

Step-by-step explanation:

I am a bit confused with the beginning part of the question. From what I understand, you are trying to solve for x and then plug x into the top equation to find the value for V. I am sorry if that is not what you are looking for. If it is, look below!

x + 9 = 5

x = 5 -9

x = -4

v(x + 9)2 = 25

v(-4 + 9)2 = 25

v(5)2 = 25

v(10) = 25

v = 25/10

v = 2.5

x + 9 = -5

x = -5 -9

x = -14

v(x + 9)2 = 25

v(-14 + 9)2 = 25

v(-5)2 = 25

v(-10) = 25

v = 25/(-10)

v = -2.5

I hope this helped! If not, I am sorry. :(

Give two examples of repeating decimals and their corresponding fractions. Show your work.

n200080 [17]

1/9 = 0.1111111111...
That's a repeating decimal because the 1 repeats over and over again.

1/3 = 0.33333333...
That's a repeating decimal because the 3 repeats over and over again.

Have an awesome day! :)
