I will let you decide what counts as a second step, I'm going to write out all the steps.

starting from original equation

49n+986=-43

49n=-1029

n=-21

Answer:

The second step is subtracting 986 from both sides

Step-by-step explanation:

The reason is because you want to isolate the variable. You can't solve it if there are numbers along with the variable in an equation.

Answer:

A. j > 11

B. x ≥ 8

Step-by-step explanation:

For A if 7j is greater than 77, then j has to be more than 11. 7 x 11= 77.

For B x has to be greater or equal to 17, and 8+9 is equal to 17.

What represents the inverse of the function f(x)=4x

Yuki888 [10]

Answer:

$\frac{x}{4}$

Step-by-step explanation:

The given function is

f(x) = 4x

As we know

f(x) = y, which implies x= $f^{-1} (y)$

Therefore,

y = 4x

x = $\frac{y}{4}$

as x= $f^{-1} (y)$

So,

$f^{-1} (y) = \frac{y}{4}$

replacing y by x in the above expression

$f^{-1} (x) = \frac{x}{4}$

So our inverse function is $\frac{x}{4}$
