Answer: The answer is 6n+7y
Step-by-step explanation: All you have to do is add like terms
Answer:
The rule is "add 5, add 10, add 20" and the rule keeps doubling.
Answer:
The value of y is 847 for x=11
Step-by-step explanation:
It is given that y is directly proportional to the square of x
This can be written mathematically as:
![y \propto x^2](https://tex.z-dn.net/?f=y%20%5Cpropto%20%20x%5E2)
Removing the proportionality symbol introduces a proportionality constant in the equation which is denoted by k
![y = kx^2](https://tex.z-dn.net/?f=y%20%3D%20kx%5E2)
Given that "When x is 5, y is 175"
![175 = k (5)^2\\175 = k*25\\k = \frac{175}{25}\\k = 7](https://tex.z-dn.net/?f=175%20%3D%20k%20%285%29%5E2%5C%5C175%20%3D%20k%2A25%5C%5Ck%20%3D%20%5Cfrac%7B175%7D%7B25%7D%5C%5Ck%20%3D%207)
Putting the value of k
![y = 7x^2](https://tex.z-dn.net/?f=y%20%3D%207x%5E2)
Now putting x = 11
![y = 7(11)^2\\y = 7 * 121\\y = 847](https://tex.z-dn.net/?f=y%20%3D%207%2811%29%5E2%5C%5Cy%20%3D%207%20%2A%20121%5C%5Cy%20%3D%20847)
Hence,
The value of y is 847 for x=11
Answer:
Give it a bit of time OK I will say the answer is in the *c'h_a-t
