Step-by-step explanation:

|x - 8| < 13

1 .

x - 8 < 13
x < 8 + 13
x < 21

x - 8 > -13
x > 8 - 13
x > -5

Combined answer

Write at least 2 numerical expressions for each written phrase below. Then, solve.

zloy xaker [14]

Answer:

a. $\frac{3}{5}(7)\text{ or }\frac{3\times 7}{5}$

b. $\frac{1}{6}(4\times 8)\text{ or }\frac{4\times 8}{6}$

Step-by-step explanation:

In numerical expressions we write numbers with the mathematical symbols ( i.e. '+', '-' etc )

a. Given phrase,

Three fifths of seven,

$\frac{3}{5}(7)$

$=\frac{3\times 7}{5}$

$=\frac{21}{5}$

$=4\frac{1}{5}$

b. One sixth the product of four and eight,

$\frac{1}{6}(4\times 8)$

$=\frac{4\times 8}{6}$

$=\frac{32}{6}$

$=5\frac{1}{3}$

- 3 + 3x = 2x – 13 I have to use more characters...

DENIUS [597]

- 3 + 3x = 2x – 13

Bring -3 to the right side of the equation by adding 3 to both sides

(- 3 + 3) + 3x = 2x – 13 + 3

0 + 3x = 2x - 10

3x = 2x - 10

Bring 2x to the other side by subtracting 2x to both sides

3x - 2x = 2x - 2x - 10

x = -10

Check:

-3 + 3(-10) = 2(-10) - 13

-3 + (-30) = -20 - 13

-33 = -33

Hope this helped!

After being rearranged and simplified, which of the following equations could be solved using the quadratic formula?

Alecsey [184]

For this case we must indicate which of the equations shown can be solved using the quadratic formula.

By definition, the quadratic formula is applied to equations of the second degree, of the form:

$ax ^ 2+ bx+ c = 0$

Option A:

$2x ^ 2-3x +10 = 2x + 21$

Rewriting we have:

$2x ^ 2-3x-2x+ 10-21 = 0\\2x ^ 2-5x-11 = 0$

This equation can be solved using the quadratic formula

Option B:

$2x ^ 2-6x-7 = 2x ^ 2$

Rewriting we have:

$2x ^ 2-2x ^ 2-6x-7 = 0\\-6x-7 = 0$

It can not be solved with the quadratic formula.

Option C:

$5x ^ 2 + 2x-4 = 2x ^ 2$

Rewriting we have:

$5x ^ 2-2x ^ 2 + 2x-4 = 0\\3x ^ 2 + 2x-4 = 0$

This equation can be solved using the quadratic formula

Option D:

$5x ^ 3-3x + 10 = 2x ^ 2$

Rewriting we have:

$5x ^ 3-2x ^ 2-3x + 10 = 0$

It can not be solved with the quadratic formula.

A and C
