The division property of equality could be used to solve which of the following equations?a. 5x= 30
b. x+ 3 = 7
c. (x+ 2) (x- 2) = 0
d. = 16

Answers

Answer 1
Answer: If you would like to know which of the above equations could be solved by the division property of equality, you can find this using the following steps:

a. 5 * x = 30     /5
    x = 30 / 5
    x = 6
b. x + 3 = 7      /-3
    x = 7 - 3 = 4
c. (x + 2) * (x - 2) = 0
    1. x = -2
    2. x = 2
d. = 16

The correct result would be a. 5 * x = 30 can be solved by the division property of equality.
Answer 2
Answer:

Answer:

Option a is correct that is 5x=30 will use division property of equality.

Step-by-step explanation:

We have been given four different equations we need to tell which one could be used to solve by division property:

In Option a:

x can will be solved by division property

5x=30

5 will divide 30 on right hand side by the transformation rule which is

when multiplication is shifted to the other side of the equation it will be in division on the other side.

x=6

Therefore, option a is correct.

Answer:

First Option {-2 , 0 , 2}

Step-by-step explanation:

A critical point occurs when the derivative is 0 or undefined.

The function in the question is undefined at x = 2 and at x = -2 because if we put x = 2 or x = -2 the denominator becomes 0 hence anything divided by 0 is undefined, and the derivative equals 0 at x = 0 so the critical points are

{-2 , 0 , 2}

Use the quotient rule to find the derivative of the function then equal it to zero

y=(x^2-1)/(x^2-4)\n\n(dy)/(dx)=((x^2-4)(2x)-(x^2-1)(2x))/((x^2-4)^2)\n\n0=((x^2-4)(2x)-(x^2-1)(2x))/((x^2-4)^2)\n\n0=2x^3-8x-2x^3+2x\n0=-6x\nx=0
