What value of x makes this statement true? 3x=2x+12 A) 2 B) 5 C) 6 D) 12

vekshin1

Answer:

The value of x = 12, makes the statement $3x=2x+12$ true

Option D is correct option.

Step-by-step explanation:

What value of x makes this statement true?

$3x=2x+12$

We need to solve the equation to find value of x

$3x=2x+12$

Subtract 2x on both sides

$3x-2x=2x+12-2x\\x=12$

So, the value of x is: x=12

So, The value of x = 12, makes the statement $3x=2x+12$ true

Option D is correct option.

[Quick Answer Needed] Which of the following shows the extraneous solution to the logarithmic equation?

Nitella [24]

Answer:

Step-by-step explanation:

Given the logarithmic equation

$\log_4x+\log_4(x-3)=\log_4(-7x+21)$

First, notice that

$x>0\\ \\x-3>0\Rightarrow x>3\\ \\-7x+21>0\Rightarrow 7x$

So, there is no possible solutions, all possible solutions will be extraneous.

Solve the equation:

$\log_4x+\log_4(x-3)=\log_4x(x-3),$

then

$\log_4x(x-3)=\log_4(-7x+21)\\ \\x(x-3)=-7x+21\\ \\x^2-3x+7x-21=0\\ \\x^2+4x-21=0\\ \\D=4^2-4\cdot 1\cdot (-21)=16+84=100\\ \\x_{1,2}=\dfrac{-4\pm 10}{2}=-7,\ 3$

Hence, $x=3$ and $x=-7$ are extraneous solutions

The inequality x + 2y ≥ 3 is satisfied by point (1, 1). True False

andre [41]

In the given statement above, in this case, the answer would be TRUE. It is true that the inequality x + 2y ≥ 3 is satisfied by point (1, 1). In order to prove this, we just have to plug in the values. 1 + 2(1) ≥ 3
So the result is 1 + 2 ≥ 3. 3 ≥ 3, which makes it true, because it states that it is "more than or equal to", therefore, our answer is true. Hope this answer helps.
