Solve the inequality:-3x-4/7 >5

Aliun [14]

x < - $\frac{13}{7}$

add $\frac{4}{7}$ to both sides

- 3x > $\frac{4}{7}$ + $\frac{35}{7}$

- 3x > $\frac{39}{7}$ ( divide both sides by - 3 )

note that when we divide/ multiply by a negative quantity we must reverse the inequality symbol

x < - $\frac{13}{7}$

Which of the following equations is the translation 2 units left of the graph of y = |x|?

nignag [31]

Answer:

The correct option is 1.

Step-by-step explanation:

The given function is

$y=|x|$

It is an absolute function. The transformation of function is defined as

$y=|x+a|+b$

Where, a is horizontal shift and b is vertical shift.

If a>0, then graph shifts a units left, if a<0, then graph shifts a units right.

If b>0, then graph shifts b units up, if b<0, then graph shifts b units down.

If is given that the graph translate 2 units left. Therefore the value of a is 2 and the value of b is 0.

The required function is

$y=|x+2|+0$

$y=|x+2|$

Therefore the correct option is 1.

A triangle has one side length of 12 inches and another of 8 inches. Describe all possible lengths of the third side. Show and e

katrin [286]

Answer:

The third side must be smaller than 20 inches and greater than 4 inches

$4$

Step-by-step explanation:

Let a, b and c be the lengths of triangle's sides. Then

$a+b>c\\ \\a+c>b\\ \\b+c>a$

Use this rule in your case. So, if a=12 and b=8, then

$12+8>c\\ \\12+c>8\\ \\8+c>12$

Hence, you get

$c-4\\ \\c>4$

From these inequalities, you can state that

$4$

So, c must be smaller than 20 inches and greater than 4 inches.

Answer:

(4x+5)(-3x-1) = -12x²-19x-5

Option A:

(-16x² + 10x - 3) + (4x² - 29x - 2) = -12x²-19x-5

Option A is correct.

Option B:

3(x - 5) - 2(6x² + 9x + 5) = -12x²-15x-25

Option B is wrong.

Option C:

2(x - 1) - 3(4x² + 7x + 1) = -12x²-19x-5

Option C is correct.

Option D:

(2x² - 11x - 9) - (14x² + 8x - 4) = -12x²-19x-5

Option D is correct.
