Which of the following inequalities has a solution x≥−3

1 answer:

6 0

Answer: A

Step-by-step explanation: 3(x-1) becomes 3x -3 ≤ 4x. Put all like variables on the same side, meaning you'll subtract 3x from both sides giving you -3 ≤ x. You can flip the equation around to make it look exactly like x ≥ -3

deff fn [24]

Answer: w = -3u/2 + 2

Step-by-step explanation:

-12u + 13 = 8w - 3

-12u + 13 + 3 = 8w -3 + 3

-12u + 16 = 8w

w = -3u/2 + 2

Which function is the inverse of f(x) = –5x – 4?

Finger [1]

Answer:

f^(-1)(x) = \frac{-1}{5} (x+4)

Step-by-step explanation:

Given is a function

$f(x) = -5x-4\\$

To find its inverse.

We must check whether f is one to one or onto first

If -5x1-4 = -5x2-4 we get x1=x2

Hence f is one to one

Also for every f(x) we can find a x so f is onto.

So inverse exists

Let

$y=-5x-4\\-5x=y+4\\x=\frac{-1}{5} (y+4)$

Replace x by f inverse and y by x

$f^(-1)(x) = \frac{-1}{5} (x+4)$
