Y is directly proportional to the square of x.
RUDIKE [14]

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

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

y = kx^2

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

175 = k (5)^2\\175 = k*25\\k = \frac{175}{25}\\k = 7

Putting the value of k

y = 7x^2

Now putting x = 11

y = 7(11)^2\\y = 7 * 121\\y = 847

Hence,

The value of y is 847 for x=11

3(x+1)=2(x-3) whats the answer
AnnyKZ [126]

Answer:

x= -9

Step-by-step explanation:

1. distribute

3(+1)=2(−3)

so it would look like this:

3+3=2x-6

2. subtract 3 from both sides

It would look like this:

3x=2x-9

3. subtract 2x from both sides

It would look like this:

x= -9

And that is your answer!!
