Y = 2x + 3<br> y = -2x + 15<br> Can you please explain how to get the answer.
-Dominant- [34]

Answer:

x = 3 and y = 9

Step-by-step explanation:

Given:

y = 2x + 3 .......................... equation i

y = -2x + 15 ........................ equation ii

since y is equals to the two functions , we can equate the two values of y . That is , equate equation i and ii , we have

2x + 3 = -2x + 15

Add 2x to both sides , we have

2x + 2x + 3 = -2x + 2x + 15

4x + 3 = 15

subtract 3 from both sides , we have

4x = 12

divide both sides by 4 , then

x = 3

substitute x = 3 into equation i to get the value of y , that is

y = 2(3) +3

y = 6 + 3

y = 9

Therefore :

x = 3 and y = 9

An experiment repeated 5 times is more reliable than an experimment repeated 20 times
shutvik [7]

Answer:

The given statement is false

Step-by-step explanation:

Given that an experiment repeated 5 times is more reliable than an experiment repeated 20 times.

The statement is false.

Any result found by way of experiment will be more reliable if more number of trials are done.  

For example, consider toss of a coin.  If we try for 2 times, we may get prob for head as 0 sometimes 1/2 or sometimes 1. This is because 2 is very short number of trials to decide.  But when you increase to 10, you may get more reliable.  SO if number of repititions increase, the more reliable the results would be.

Anton [14]

Answer:

Step-by-step explanation:

-2x + 3 = 0

-2x = -3

x = 3/2

-x^2 + 2x + 3 = (-3/2)^2 + 2 × 3/2 + 3

= 9/4 + 3 + 3

= 9/4 + 6

= 33/4

Hope this helps
