I don’t know how to solve this

Answer:

x ∈ (-∞, 9) U (-1, ∞)

Step-by-step explanation:

Get the absolute value by itself. Do that by multiplying by 4.

|3x +15| > 12

This resolves to two cases:

x +5 > 4 . . . . divide by 3

x > -1 . . . . . . .subtract 5

x +5 < -4 . . . . divide by -3

x < -9 . . . . . . . subtract 5

Then the solution in interval notation is ...

x ∈ (-∞, 9) U (-1, ∞)

1/4 x 2/5 x 3/6 x 4/7 x 5/8 x 6/9 x 7/n=?

postnew [5]

Answer:

c. $\frac{1}{12n} = {[12n]}^{-1}$

Step-by-step explanation:

$[\frac{1}{4}][\frac{2}{5}][\frac{1}{2}][\frac{4}{7}][\frac{5}{8}][\frac{2}{3}][\frac{7}{n}] = \frac{560}{6720n} = [12n]^{-1} = \frac{1}{12n}$

$\frac{2}{3} = \frac{6}{9}\\ \\ \frac{1}{2} = \frac{3}{6}$

* To make this simpler, reduce these two fractions in lowest terms.

Each pair of polygons below is similar. Find the value of x. Some answers may be decimals.

sergiy2304 [10]

Answer:

The answer to your question is below.

Step-by-step explanation:

14.- Use proportions to solve these problems.

$\frac{x + 6}{10} = \frac{x + 9}{14}$

14(x + 6) = 10(x + 9)

14x + 84 = 10x + 90

14x - 10x = 90 - 84

4x = 6

x = 6/4

x = 3/2

15.- $\frac{x - 1}{8} = \frac{x + 2}{10}$

10(x - 1) = 8(x + 2)

10x - 10 = 8x + 16

10x - 8x = 16 + 10

2x = 26

x = 26 / 2

x = 13

16.- $\frac{x + 1}{9} = \frac{10/3}{5}$

5(x + 1) = 9(10/3)

5x + 5 = 30

5x = 30 - 5

5x = 25

x = 25 / 5

x = 5
