2x = -11 + 9

2x-9= -11

Move -9 to the other side

Sign changes from -9 to +9

2x-9+9= -11+9

2x= -11+9

2x=-2

Divide both sides by 2

2x/2= -2/2

Answer: x= -1

In the isosceles △ABC m∠ACB=120° and AD is an altitude to leg BC . What is the distance from D to base AB , if CD=4cm?
7nadin3 [17]

Correct answer is: distance from D to AB is 6cm

Solution:-

Let us assume E is the altitude drawn from D to AB.

Given that m∠ACB=120° and ABC is isosceles which means

m∠ABC=m∠BAC = \frac{180-120}{2}=30

And AC= BC

Let AC=BC=x

Then from ΔACD , cos(∠ACD) = \frac{DC}{AC} =\frac{4}{x}

Since DCB is a straight line m∠ACD+m∠ACB =180

                                              m∠ACD = 180-m∠ACB = 60

Hence cos(60)=\frac{4}{x}

          x=\frac{4}{cos60}= 8

Now let us consider ΔBDE, sin(∠DBE) = \frac{DE}{DB} =\frac{DE}{DA+AB} = \frac{DE}{4+8}

DE = 12sin(30) = 6cm

The population full-time equivalent number of students (FTES) at Lake Tahoe Community College for 2005-2006 through 2010-2011 wa
makkiz [27]

The mean of the set of numbers that are given in this situation regarding the population will be 1809.33.

<h3>How to solve the mean</h3>

The mean of the numbers will be:

= (1,585 + 1,690 + 1,735 + 1,935 + 2,021 + 1,890) / 6

= 1809.33

The median of the numbers will be:

= (1735 + 1890) / 2

= 1812.50

Also, from the complete question, the first quartile will be 1690 and the third quartile is 1935.

Which two points are on the graph of y = -x + 3?
ch4aika [34]

The points (0, 3) and (4, -1) are on the graph of y = -x + 3.

I have a site that I use a lot that is perfect for problems like these. It's called Desmos.com. It's basically a free online graphing calculator that is super helpful for most problems relating to graphs.

How can complex fractions be used to solve problems involving ratios
strojnjashka [21]
When you have ratios, and some unknowns, you can create complex fractions from them. Bring them to the same denominator, and solve for x.

Example - we have this proportion:
2-x
5-45
And we can change it into fraction:
\frac{2}{5}=\frac{x}{45}

\frac{2*9}{5*9}=\frac{x}{45}

\frac{18}{45}=\frac{x}{45}
18=x

In case of more complex fractions it may come in handy.
