<h2><u>Answer:</u></h2>

$\bold{x}$ ≥ $\bold{-6}$

<h2><u>Solution Steps:</u></h2>

______________________________

<h3>1.) <u>Add 7 to both sides:</u></h3>

$-7+7=$ Cancels Out

$11+7=18$

<em>- We have to get rid of both numbers on each side, so to do so, we do the opposite of what we see: Since we have a negative 7, we add 7 on each side.</em>

<u>Equation at the end of Step 1:</u>

$-3x$ ≤ $18$

<h3>2.) <u>Divide both sides by -3:</u></h3>

$-3$ ÷ $-3=$ Cancels Out

$18$ ÷ $-3=-6$

<em> - We have to get rid of numbers on each side, so do to so, we do the opposite of what we see. Since we have a negative 3 being multiplied, we divide by -3 instead. </em>

<em> - Since -3 is negative, the inequality direction is changed as well. </em>

<u>Equation at the end of Step 2:</u>

$x$ ≥ $-6$

Answer:

B 61 1/2 inches

Step-by-step explanation:

The longest flower is 8 1/2 inches

There are 2 flowers that are 7 3/4 inches

There are 5 flowers that are 7 1/2 inches

That makes 8 flowers

8 1/2 + 2(7 3/4) + 5 (7 1/2) = total length of flowers

Distribute

8 1/2 + 14 6/4 + 35 5/2

Add the whole numbers

8+14+35 = 57

Now we add the fractions

1/2 + 6/4+5/2

1/2+5/2 = 6/2 =3

6/4 = 3/2 = 1 1/2

3 + 1 1/2 = 4 1/2

Whole numbers plus fractions

57 + 4 1/2

61 1/2 inches

Find the definite integral from 0 to 1/16 of arcsin(8x)/sqrt(1-64x^2)dx

kolezko [41]

$\displaystyle\int_0^{1/16}\frac{\arcsin8x}{\sqrt{1-64x^2}}\,\mathrm dx$

First let $y=8x$ , so that $\mathrm dx=\dfrac{\mathrm dy}8$ to write the integral as

$\displaystyle\frac18\int_0^{1/2}\frac{\arcsin y}{\sqrt{1-y^2}}\,\mathrm dy$

Now recall that $(\arcsin y)'=\dfrac1{\sqrt{1-y^2}}$ , so substituting $z=\arcsin y$ should do the trick. The integral then becomes

$\displaystyle\frac18\int_0^{\pi/6}z\,\mathrm dz=\frac1{16}z^2\bigg|_{z=0}^{z=\pi/6}=\frac{\pi^2}{576}$

Given that the measure of angle 6 is 1/8 of measure of angle 4. Find the measures of these two angles if a∥b.

vredina [299]

Answer:

see explanation

Step-by-step explanation:

Let ∠4 be x then ∠6 is $\frac{1}{8}$ x

∠4 and ∠6 are same side interior angles and are supplementary, thus

x + $\frac{1}{8}$ x = 180

Multiply through by 8 to clear the fraction

8x + x = 1440, that is

9x = 1440 ( divide both sides by 9 )

x = 160

Hence ∠4 = 160° and ∠6 = 160° ÷ 8 = 20°

Pleaseeeee help I’m begging someone I PROMISE. I will mark brainlest

Lerok [7]

Answer:

Step-by-step explanation:

a) x>0 → items can not be negative

b) c(2,000) = 5,000+1.3(2,000) = $7,600

c)5,000+1.3x<10,000

5,000-5,000+1.3x<10,000-5,000

1.3x<5,000

x<3846 items
