Answer: No, it is not a direct proportion equation

Explanation:

Direct proportions are always in the form $y = kx$ where k is any nonzero real number. So for example, we could have the equation $y = 9x$ . The y intercept of any direct proportion is always zero. Visually, such equations will go through the origin.

Something like $y = \frac{2}{3}x-7$ has a y intercept of -7 and it doesn't fit the form $y = kx$ , so it's not a direct proportion equation.

❀ $\huge\underline{ \underline{Solution :-}}$

$( {y}^{2} + \frac{5}{7} )( {y}^{2} - \frac{14}{5} )$

To solve, use the algebraic identity ➺

(x + a)( x + b) = x² + (a + b)x + ab

$( {y}^{2} + \frac{5}{7} )( {y}^{2} - \frac{14}{5} ) \\ = ({y}^{2}) ^{2} + ( \frac{5}{7} + - \frac{14}{5} ) {y}^{2} + \frac{5}{7} \times - \frac{14}{5} \\ = {y}^{4} - \frac{73}{35} {y}^{2} - 2$

What is the answer to 3x+2

Mademuasel [1]

3x+2 can't be further simplified because it is already in simplest forms. The only way to simplify this equation is if it has a value of x.

What is the value of n in the equation shown below? 2^2 x 2^n = (2^4)^3

AlekseyPX

So 2^2*2^n=(2^4)^3
2^2= 4
2^4=16
Then 16^3=4096
Now what we have is 4*2^n= 4096
You need to get the 2^n by itself so divide out the 4
4096/4= 1024
2^n=1024
Now you need to do log to get rid of that exponent
Therefore: n=log2(2024) or n=10

ANSWER
n=10
