Given the following absolute value function find the range. ƒ(x) = |x + 5| - 8

1 answer:

7 0

The result of an absolute value operation is never negative. So the smallest that the expression |x+5| can be is 0.

Tacking on "-8" to |x+5| leads to |x+5|-8

The range of this is [-8, infinity) since the smallest |x+5|-8 can be is -8. All I did was subtract 8 from the smallest value of |x+5|

Final Answer: choice C)

Find x (steps pls) | x - 7| = 2 (i dunt understand the | in the questions)

kirill [66]

these two bars | | mean absolute value

here's how to find x

| x - 7| = 2

first apply the absolute rule

x - 7 = 2 x - 7 = -2

in both equations add 7 on both sides

x - 7 + 7 = 2 + 7 x - 7 + 7 = -2 + 7

then simplify the expressions

x = 9 x = 5

now combine these two solutions to get your answer

x = 9 or x = 5

hopefully my explanation helps

The length of a rectangle is 2 meters less than 3 times the width. The perimeter is 44

Yakvenalex [24]

Answer:

Width of rectangle = 6 meters

Step-by-step explanation:

Let

Width of rectangle = x

Length of rectangle = 3x-2

Perimeter of rectangle = 44 meters

We need to find:

The Width of rectangle.

The formula used is:

$Perimeter\:of\:rectangle=2(Length\times Width)$

Putting values and finding value of x

$Perimeter\:of\:rectangle=2(Length\times Width)\\44=2(3x-2+x)\\44=2(4x-2)\\44=8x-4\\8x=44+4\\8x=48\\x=\frac{48}{8}\\x=6$

So, we get the value of x = 6.

We know that Width of rectangle = x = 6

So, Width of rectangle = 6 meters
