Answer:

3/4

Step-by-step explanation:

Start by simplifying (2x-x) to just (x)

The equation should now look like this: 12+x=9x-6

Now subtract the x on the left side of the equation on both sides.

The equation should now look like this: 12=8x-6

Now add 6 on both sides

The equation should now look like this: 6=8x

To get x by itself you must divide 8 on both sides

The equation should now look like this 6/8=x

Don't forget to simplify your fractions!

6/8 simplified is 3/4, giving you the answer 3/4

Please help me with this problem. How do I find x?

inysia [295]

Assuming that is 2 right triangles sharing a side
height^2 = 20^2 -7^2
height^2 = 400 - 49
height^2 = 351
height = 18.7349939952 
x^2 = 24^2 - 18.7349939952^2
x^2 = 576 -351
x^2 = 225
x = 15

Which action will solve the equation?. m + 20 = 9. . Add 9 to each side.. Subtract 9 from each side.. Add 20 to each side.. Subt

Kruka [31]

M + 20 = 9
u need to subtract 20 from both sides because u want to isolate m

m + 20 = 9
m + 20 - 20 = 9 - 20
m = - 11

Find the derivative of f(x) = negative 9 divided by x at x = -8.

marusya05 [52]

Answer:

$f'(-8)=\frac{9}{64}$

Step-by-step explanation:

Given the function

$f(x)=\frac{-9}{x}$

We can rewrite it as

$f(x)=-9x^{-1}$

Now we can apply the power rule

$f'(x)=9x^{-2}$

Now we can rewrite it

$f'(x)=\frac{9}{x^{2} }$

Now we can plug in x=-8

$f'(-8)=\frac{9}{(-8)^{2} }\\f'(-8)=\frac{9}{64}$
