I believe It is A. infinitely solutions
Answer:
Step-by-step explanation:
7x - 9 = x + 3
6x - 9 = 3
6x = 12
x = 2
7(2) - 9 + 2 + 3
14 - 9 + 5
5 + 5 = 10
Answer:
6/5
Step-by-step explanation:
(42-18) / (35 - 15) = 24 / 20 = 6 / 5
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:

Removing the proportionality symbol introduces a proportionality constant in the equation which is denoted by k

Given that "When x is 5, y is 175"

Putting the value of k

Now putting x = 11

Hence,
The value of y is 847 for x=11
