What logarithmic equation has the same solution as x-4=2^3

kumpel [21]

What logarithmic equation has the same solution as x-4=2^3

Solution:

x-4=2³

x-4=2*2*2

x-4=8

TO solve for x, Let us add 4 on both sides

x-4+4=8+4

x+0=12

So, x=12

But, x=12 is not a logarithmic equation and there are no options

So, an equation like, x=㏒ $10^{12}$

As log has base 10,

So, x=㏒ $10^{12}$ =12

So, logarithmic equation like x=log $10^{12}$ has same solution as x-4=2³

Answer:

24) A

22) B

Step-by-step explanation:

24)

Original Price: d

Sale: 30%

A sale means that a value is subtracted from the original price

d - 30% = 0.7d

All options given:

A) 0.3d

B) 0.7d

C) d - 0.3d = 0.7d

D) (1.0 - 0.3)d = 0.7(d) = 0.7d

All of these options are equal to the price after the sale, except A.

A is the answer to question 24

22) m > 0, n > 0 Use an example to represent m and n

m = 1, n = 2 = -0.5

-0.5 is a rational, negative number

The answer to question 22 is B

Solve the equation 8y2 – 2y - 1 = 0.

lapo4ka [179]

Hi there! :)

Answer:

$\huge\boxed{y = -1/4, 1/2.}$

Given the equation:

8y² - 2y - 1 = 0

Find two numbers that multiply into -1 and sum up to -2. Remember, the 8 as the leading coefficient must be taken into account.

After guessing and checking, we get:

(4y + 1) (2y - 1) = 0

Use the Zero-Product Property to solve for y:

4y + 1 =

4y = -1

y = -1/4

--------------

2y - 1 = 0

2y = 1

y = 1/2

Therefore, solutions to this equation are:

y = -1/4, 1/2.
