Use the elimination method to find all solutions of the system:
weqwewe [10]

Answer:

x = 3    and    y = 4

Step-by-step explanation:

Given

[Correct Question]

x^2 - 2y = 1

x^2 + 5y = 29

Required

Solve using elimination

First, we eliminate x.

Subtract equation (1) from (2)

x^2 - x^2 + 5y - (-2y) = 29 - 1\\

5y - (-2y) = 28

5y +2y = 28

7y = 28

Divide through ny 7

y = 4

Take x^2 - 2y = 1

Make x^2 the subject

x^2 = 1 + 2y

Substitute 4 for y

x^2 = 1 + 2*4

x^2 = 1 + 8

x^2 = 9

Take square roots

x = \sqrt 9

x = 3

James was trying to sleep one night but there was too much noise around him. His clock ticked every
g100num [7]

Answer:

<em>It will occur zero times between midnight and one o'clock.</em>

Step-by-step explanation:

<u>Least Common Multiple (LCM)</u>

Three events keep James from sleeping: his clock ticking every 20 seconds, a tap dripping every 15 seconds, and his dog snoring every 27 seconds.

All three events happened together at midnight. They will happen together again the first time the numbers 20, 15, and 27 have a common multiple. This is the LCM.

List the prime factors of each number:

20: 2,2,5

15: 3,5

27: 3,3,3

Now multiply all the factors the maximum number of times they appear:

LCM=2*2*3*3*3*5=540

(a) All the events will happen together again after 540 minutes.

(b) Since 540 minutes = 9 hours, this event won't happen again until 9 am. Thus, it will occur zero times between midnight and one o'clock.
