Whats the simplified form of the expression (t^4/10y^4)-4

1 answer:

3 0

$\bf \left( \cfrac{t^4}{10y^4} \right)^{-4}\implies \left( \cfrac{10y^4}{t^4} \right)^4\impliedby \textit{now let's distribute the exponent}
\\\\\\
\left( \cfrac{10^4y^{4\cdot 4}}{t^{4\cdot 4}} \right)\implies \cfrac{10000y^{16}}{t^{16}}$

What is the solution to the system of equations below? y=-1/3x+9 and y=2/3x-12

Lady bird [3.3K]

<u>Answer:</u>

The correct answer option is (21, 2).

<u>Step-by-step explanation:</u>

We are given the following two equations and we are to find the solution to this system of equations:

$y=-\frac{1}{3} x+9$ --- (1)

$y=\frac{2}{3} x-12$ --- (2)

Since the left hand side of the both the equation is equal so we can equate the right hand sides of these equations equal to each other.

$-\frac{1}{3} x+9 = \frac{2}{3} x-12$

$\frac{2}{3} x+\frac{1}{3} x = 9+12$

x = 21

Substituting this value of x in (2) to find y:

$y=\frac{2}{3} (21) - 12$

y = 2
