If y=8-x then you can plug that into the equation like 7=2-(8-x). When you distribute the equation becomes 7=2-8+x. Once you combine like terms the equation becomes 7=-6+x. Then you subtract 6 from both sides, which gives you 13=x.
To find y just put 13 where x was in the first equation. Y=8-13.
Y=-5
X=13
Answer:
We want to find two irrational numbers between 0.8275496 and 0.84218972
The easier way to solve this is to remember that the product between an irrational number and a rational number (different than zero) is irrational. Then:
Now, remember that the square root of a prime number is always irrational, so we can start working with that.
√5 = 2.236......
As our two rational numbers are 0.8275496 and 0.84218972, any irrational number such that the first two digits after the decimal point are 0.83 will be between these, then we can do the calculations with rational numbers:
2.236 and 0.83
2.236*A = 0.83....
Where A is a rational number:
A = 0.83/2.236 = 0.371
Now we know that 0.371 is a rational number, then:
0.371*√5 will be an irrational number, and:
0.371*√5 = 0.82958....
then 0.371*√5 is an irrational number between 0.8275496 and 0.84218972
Now let's find other, this time using √2.
√2 = 1.414....
1.414*A = 0.83
A = 0.83/1.414 = 0.587
Then:
0.587*√2 will be an irrational number, and:
0.587*√2 = 0.830143...
So 0.587*√2 is an irrational number between 0.8275496 and 0.84218972
Answer:
The function is f(x) = x + 2 when x > 4 and
x when x = 4
Step-by-step explanation:
Given - There were 4 people at the starting meeting. If those 4 people told
2 people about the march, and those 2 people told another 2,
To find - How would we write this function?
Proof -
As given, initially , Total number of people = 4
After that, those 4 people told 2 people about the march
This means,
Total people know about the march = 4 + 2 = 6
Now,
Those 2 people told another 2
This means,
Total people know about the march = 6 + 2 = 8
∴ we get
The function is f(x) = x + 2 when x > 4 and
x when x = 4
