Answer:

$\frac{2}{15}$

Step-by-step explanation:

Substitute the values for a and c into the expression

- 2c + a

= - 2× $\frac{3}{10}$ + $\frac{11}{15}$

= - $\frac{3}{5}$ + $\frac{11}{15}$

= - $\frac{3(3)}{5(3)}$ + $\frac{11}{15}$

= - $\frac{9}{15}$ + $\frac{11}{15}$

= $\frac{2}{15}$

If f(x)=5x-3 and f(x)=7, what is the value of x?

Rama09 [41]

5x - 3 = 7

Add 3 to both sides.

5x = 10

Divide both sides by 5.

x = 2

The value of x is 2.

[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
