Answer: Hi!

We can simplify this by combining like terms:

-12w + 7w - 3 - 6

-12w + 7w = -5w

-3 - 6 = -9

Out equation now looks like this:

-5w - 9

There's nothing left to simplify, so we're done!

For f(x)= 5 over x-7 when will. f(x) equal 8?

Sindrei [870]

Answer:

Therefore at

$x=\dfrac{1}{3}$

we have

$f(x)=8$

Step-by-step explanation:

Given:

$f(x)=\dfrac{5}{x}-7$

To Find:

x = ? when f(x) = 8

Solution:

$f(x)=\dfrac{5}{x}-7$ ..............Given

Substituting f(x) = 8 we get

$8=\dfrac{5}{x}-7$

Adding 7 to both the side

$8+7=\dfrac{5}{x}-7+7$

$15=\dfrac{5}{x}$

$x=\dfrac{5}{15}=\dfrac{1}{3}$

Therefore at

$x=\dfrac{1}{3}$

we have

$f(x)=8$
