What is the value of x please help me

Mathematics
1 answer:
Tju [1.3M]3 years ago
7 0

Answer:

<h2>x = 4</h2>

Step-by-step explanation:

ΔLMN and ΔPMQ are similar. Therefore thw sides are in proportion:

\dfrac{LM}{PM}=\dfrac{NM}{QM}

We have:

LM = 3 + 9 = 12

PM = 9

NM = x + 12

QM = 12

Substitute:

\dfrac{12}{9}=\dfrac{x+12}{12}                <em>cross multiply</em>

9(x+12)=(12)(12)

9(x+12)=144             <em>divide both sides by 9</em>

\dfrac{9(x+12)}{9}=\dfrac{144}{9}

x+12=16             <em>subtract 12 from both sides</em>

x=4

Write the slope-intercept form of the line with a slope of 2 and a y-intercept of -4. Include your work in your final answer. Ty
xenn [34]

Answer:

The formula for slope intercept is y=mx+b and m is the slope and B is our y intercept. so if we just input our values:

y=2x-4

you also you could write the slope as 2/1 since the slope is rise over run (rise/run)

How do I solve these equations
Sever21 [200]
You need to know the properties of each function.
Tan is opposite (y) over adjacent (x).  Sin>0 means that sin is positive, therefore, it is located on either quadrant 1 or 2. Tan=4/3  so it is located in quadrant 1.
The side of the triangle must be Adjacent=3  opposite=4 and hypotenuse=5
Now, you are asked to find the half angle of Cos which is 
\sqrt{\frac{1+cos}{2} }
By following the formula, cos=3/5 then:
\sqrt{ \frac{1- \frac{3}{5} }{2} }    Multiply everything (inside the square          \sqrt{ \frac{5+3}{10} }                  root) by 5
\frac{2 \sqrt{2} }{ \sqrt{10} }
\frac{2 \sqrt{20} }{10}                Then just simplify
\frac{ \sqrt{20} }{5}      The answer is Square root of 20 over 5
