Step-by-step explanation:

We can write this as a ratio

x 9

---- = --------

10 15

Using cross products

15x = 10*9

15x = 90

Divide by 15

15x/15 = 90/15

x =6

What is the value of a when we rewrite 8^x as a^-x/9

Andre45 [30]

Answer:

$a = \frac{1}{134217728}$

Step-by-step explanation:

Given

$8^x = a^{-x/9}$

Required

Find a

Take log of both sides

$log(8^x) = log(a^{-x/9})$

Apply law of logarithm

$x\ log(8) = (-x/9) log(a)$

Divide both sides by a

$log(8) = -\frac{1}{9} log(a)$

Multiply both sides by -9

$-9\ log(8) = log(a)$

Apply law of logarithm

$log(8^{-9}) = log(a)$

Cancel out log

$8^{-9} = a$

Rewrite as:

$a = 8^{-9}$

Apply law of indices

$a = \frac{1}{8^9}$

$a = \frac{1}{134217728}$

Points (5, 3) and (6, 2) lie on line k. Which is the slope of the line that is parallel to k?

Over [174]

Slope of k=(3-2)/5-6
=-1
parallel lines have equal slopes
so slope of line parallel to k=-1
