Solve for x. 15 = |3x| A) x = 5 or x = −5 Eliminate B) x = 12 or x = −5 C) x = 5 or x = −12 D) x = 12 or x = −12

x=-5,x=+5

Step-by-step explanation:

The question says 15=|3x|

So to solve this question we will have to eliminate the || from 3x and to do so we will transfer it to 15... when it gets to 15 it will be + or - 15

So let's solve

Starting from +15=3x

Make x the subject of formula

x=+5

Let's move to the -15=3x

Make x the subject of formula

x=-5

Therefore x is either+5 or -5

That's the final answer for the given question...

I believe this will help you to understand it better

y = x + 95

y = 42 + 95

y=137 mm hg

d

step-by-step explanation:

by observation, we can see that the the graph is simply the graph of y = |x| that has been shifted 4 units downwards and 3 units to the left.

we can recognize in choice d :

y = | x + 3 |   - 4 (rewriting in general form)

y = | x - (- 3) |   - 4

the "-4 " term means   that the graph has been shifted by 4 units in the negative y direction

the "-3 " term means   that the graph has been shifted by 3 units in the negative x direction

this matches our observation of the graph described above.
