Veseljchak [2.6K]

Answer:

Step-by-step explanation:

<h2>Given,</h2>

11x - 16 = -49

=> 11x = - 49 + 16

=> 11x = -33

$= > x = \frac{ - 33}{11}$

=> x = -3 (Ans)

What are the potential solutions of log4x+log4(x+6)=2?

lions [1.4K]

The potential solutions of $log_4x+log_4(x+6)=2$ are 2 and -8.

<h3>Properties of Logarithms</h3>

From the properties of logarithms, you can rewrite logarithmic expressions.

The main properties are:

Product Rule for Logarithms - $log_{b}(a*c)=log_{b}a+log_{b}c$
Quotient Rule for Logarithms - $log_{b}(\frac{a}{c} )=log_{b}a-log_{b}c$
Power Rule for Logarithms - $log_{b}(a^c)=c*log_{b}a$

The exercise asks the potential solutions for $log_4x+log_4(x+6)=2$ . In this expression you can apply the Product Rule for Logarithms.

$log_4x+log_4(x+6)=2\\ \\ x*(x+6)=4^2\\ \\ x^2+6x=16\\ \\ x^2+6x-16=0$

Now you should solve the quadratic equation.

Δ= $b^2-4ac=36-4*1*(-16)=36+64=100$ . Thus, x will be $x_{1,\:2}=\frac{-6\pm \:\sqrt{100} }{2\cdot \:1}=\frac{-6\pm \:10}{2}$ . Then:

$x_1=\frac{-6+10}{2}=\frac{4}{2} =2\\ \\ \:x_2=\frac{-6-10}{2}=\frac{-16}{2} =-8$

The potential solutions are 2 and -8.

Find all the zeros of the equation. -3x^4+27x^2+1200=0 PLEASE HELP and show work

asambeis [7]

Answer: x=−5 or x=5

Step-by-step explanation:

−3x4+27x2+1200=0

Step 1: Factor left side of equation.

−3(x2+16)(x+5)(x−5)=0

Step 2: Set factors equal to 0.

x2+16=0 or x+5=0 or x−5=0

x=−5 or x=5
