If x = y then 3x = 3y property of equality

1 answer:

Debora [2.8K]2 years ago

Answer:

Multiplication property of equality

Step-by-step explanation:

The multiplication property of equality states that if x = 1, then you can multiply both sides by the same number and both sides will stay equal to each other. Therefore, if x = y, then you can multiply both sides by the 3 to make 3x = 3y and they will still be equal to each other.

I hope you find this helpful. :)

If x and y are two rational numbers such that x < y , then ______ is a rational number in between x and y.

stich3 [128]

Answer:

$\dfrac{x+y}{2}$

Step-by-step explanation:

Let first number be x and another number is y.

A rational number is a fraction that can be expressed in the form of x/y.

A rational number between x and y is given by :

$R=\dfrac{x+y}{2}$

So,

If x and y are two rational numbers such that x < y , then $\dfrac{x+y}{2}$ is a rational number in between x and y.

Solve the equation 2x^2-3x-6=0 give your answer correct to two decimal places

IRISSAK [1]

Answer:

<h2>x = - 1.14 or x = 2.64</h2>

Step-by-step explanation:

2x² - 3x - 6 = 0

Using the quadratic formula

$x = \frac{ - b± \sqrt{ {b}^{2} - 4ac} }{2a}$

a = 2 , b = - 3 , c = 6

Substituting the values into the above formula

We have

$x = \frac{ - - 3± \sqrt{ { - 3}^{2} - 4(2)( - 6)} }{2(2)}$

$x = \frac{3± \sqrt{9 +48 } }{4}$

$x = \frac{3± \sqrt{57} }{4}$

$x = \frac{3 - \sqrt{57} }{4} \: \: \: \: or \: \: \: \: \: x = \frac{3 + \sqrt{57} }{4}$

We have the final answer as

<h3>x = - 1.14 or x = 2.64</h3>

Hope this helps you
