Mathematics

Answer:

y = 49

Step-by-step explanation:

y ∝ x²

=> y = kx²

<u><em>Where k is the constant of proportionality</em></u>

k = 1 (We've found this out in the previous question)

Now,

y = ? when x = 7

<u><em>The above equation becomes:</em></u>

=> y = (1)(7)²

=> y = (1)(49)

=> y = 49

Select the correct answer. which expression is equivalent to the given expression? assume the denominator does not equal zero. a

Alexxandr [17]

If the denominator does not equal 0, the equivalent expression of $\frac{14x^4y^6}{7x^8y^2}$ is $\frac{2y^{4}}{x^{4}}$ $\frac{x^{10} y^{14}}{729}$

<h3>How to determine the equivalent expression?</h3>

The expression is given as:

$\frac{14x^4y^6}{7x^8y^2}$

Divide 14 by 7

$\frac{14x^4y^6}{7x^8y^2} = \frac{2x^4y^6}{x^8y^2}$

Apply the law of indices

$\frac{14x^4y^6}{7x^8y^2} = \frac{2y^{6-2}}{x^{8-4}}$

Evaluate the differences in the exponents

$\frac{14x^4y^6}{7x^8y^2} = \frac{2y^{4}}{x^{4}}$

Hence, the equivalent expression of $\frac{14x^4y^6}{7x^8y^2}$ is $\frac{2y^{4}}{x^{4}}$

If a=-3 what would 3a^2 equal

eduard

Answer:

Step-by-step explanation:

All you have to do is plug $a$ into the equation.

$3a^2$

$3(3)^2$

3 squared equals 9.

$3(9)$

Now multiply 3 times 9.

$=27$

I hope this helps! :)
