Answer: 2

<u>Step-by-step explanation:</u>

3 ln (2) + ln (8) = 2 ln (4x)

ln (2)³ + ln (8) = ln (4x)²

ln (2³ · 8) = ln (4x)²

(2³ · 8) = (4x)²

64 = 16x²

4 = x²

±2 = x

-2 is an extraneous solution because x > 0

The only valid answer is x = 2

Which graph shows a system of equations with no solutions?

Graph of Parallel lines shows a system of equations with no solutions

Step-by-step explanation:

Consider a set of equations

$7x - 2y = 16\\21x + 6y =24$

If we solve this both equations using any one of the solving method, (Substitution method) then we will get

$7x-2y=16\\7x=16+2y\\x=\frac{16+2y}{7}$

substituting the following x in 2nd equation (21x + 6y = 24) We get

$21(\frac{16+2y}{7} )+6y=24\\3(16+2y)+6y=24\\48+6y+6y=24\\12y=24-48\\y=-\frac{24}{12} \\y=-2$

Put y= -2 in x equation

$x=\frac{16+2(-2)}{7}\\ x=\frac{16-4}{7}\\\x=\frac{12}{7} \\x=1.71$

Comparing these (x,y) values we can understand that they never meet at a point
