Let x be the number of treats bought
Let y be the pounds of food bought
25= 2y+x
Given that she has buys 9 pounds of dog food:
25= 2(9)+x
25=18 +x
25-18 =x
7=x
With the money she has left over, she can buy 7 treats.
Hope I helped :)
The time has to be greater than 0, and positive.
Meaning its B, because its not negative and is greater than 0.
Answer:
200
Step-by-step explanation:
The value of x is ±0.7071 and x is an irrational number
<h3>How to solve for x?</h3>
The equation is given as:
![4x^2 = 2](https://tex.z-dn.net/?f=4x%5E2%20%3D%202)
Divide by 4
![x^2 = 0.5](https://tex.z-dn.net/?f=x%5E2%20%3D%200.5)
Take the square roots
![x = \pm 0.7071](https://tex.z-dn.net/?f=x%20%3D%20%5Cpm%200.7071)
Hence, the value of x is ±0.7071
<h3>How to prove that x is irrational?</h3>
The equation is given as:
![4^x = 5](https://tex.z-dn.net/?f=4%5Ex%20%3D%205)
Take the logarithm of both sides
![x\log(4) = \log(5)](https://tex.z-dn.net/?f=x%5Clog%284%29%20%3D%20%5Clog%285%29)
Divide both sides by log(4)
x = 1.16096....
The above number is a non-terminating decimal.
Non-terminating decimals cannot be represented as fractions of two integers
Hence, x is an irrational number
