Solve the inequality –1 > –2(x – 4) – 5(4x – 7).

Ksivusya [100]

Answer:

$x > 2$

Step-by-step explanation:

$–1 > –2(x – 4) – 5(4x – 7)$

$–1 > –2x + 8 –20x + 35$

$–1 > - 22x + 43$

$- 1 - 43 > - 22x$

$- 44 > - 22x$

$\frac{ - 44}{ - 22} < \frac{ - 22x}{ - 22}$

$2 < x$

$x > 2$

What is the universe of f(x)=3/4x

Travka [436]

I assume you mean the inverse function. To find the inverse function of a given function, start from the expression $y = f(x)$ and solve for x:

$y = \dfrac{3}{4} x$

Multiply both sides by 4:

$4y = 3x$

Divide both sides by 3:

$\dfrac{4}{3}y = x$

So this is the inverse function.
