How do you solve for y in the equation: <img src="https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7By%7D%20%3Dy-6" id="TexFormula1" title

kozerog [31]

No it isn't.

Explanation:

x/y * y = (y-6) * y

x = y^2 - 6y

A function gives just one y for every x

In this case there will always be 2 y's for every x

Example:

y can be

y = 6

y =−6

(0,-6) & (0,6)

How many solution does 2x – 1 = 1 – 2x have?

ss7ja [257]

Answer:

Step-by-step explanation:

Hello,

2x – 1 = 1 – 2x

<=> 2x-1+2x=1

<=> 4x-1=1

<=> 4x = 1+1=2

<=> x = 2/4 = 1/2

Then there is only one solution.

Thanks

What is the value of es026-1.jpg?

Kay [80]

Answer:

Value of $[(\frac{2}{3}) ^0]^{-3}$ is, 1

Step-by-step explanation:

To find the value of $[(\frac{2}{3})^0]^{-3}$

Using exponents power rule:

$(a^m)^n = a^{mn}$

then;

$(\frac{2}{3})^{0 \cdot (-3)}$

Simplify:

$(\frac{2}{3})^{0}$

By Zero exponent rule: Anything raised to the power 0 is 1. i.e,

$a^0 = 1$

then;

$(\frac{2}{3})^{0}$ = 1

Therefore, the value of $[(\frac{2}{3}) ^0]^{-3}$ is, 1
