In geometry, a transversal is a line that intersects two or more other (often parallel ) lines. In the figure below, line n is a transversal cutting lines l and m . When two or more lines are cut by a transversal, the angles which occupy the same relative position are called corresponding angles .

Remember

we can do anything to an equation as long as we do it to both sides

try to isolate the variable

you have 2 types
x+b=c
x/b=c

fior the first type, minus b from both sides to get
x=c-b

for the second, multiply both sides by b to get rid of the fraction to get
x=cb

also remember that -x times -1=x

b.add 25 to both sides
-a=20
multiply -1
a=-20

c.
-t/8=-4
multiply both sides by 8
-t=-32
mutiply -1
t=32

d. -n/-5=-30
mulitply both sides by -5
-n=150
multiply both sides by -1
n=-150

e. multiply both sides by 12
-l=144
multiply b y-1
l=-144

What is the rate of change between the interval of x = 3 pi over 2 and x = 2π?

galina1969 [7]

Check the picture below.

$\bf slope = m = \cfrac{rise}{run} \implies 
\cfrac{ f(x_2) - f(x_1)}{ x_2 - x_1}\impliedby 
\begin{array}{llll}
average~rate\\
of~change
\end{array}\\\\
-------------------------------\\\\
\begin{cases}
x_1=\frac{3\pi }{2}\\
x_2=2\pi 
\end{cases}\implies \cfrac{f(2\pi )-f\left( \frac{3\pi }{2} \right)}{2\pi -\frac{3\pi }{2} }\implies \cfrac{3-1}{\frac{4\pi -3\pi }{2}}\implies \cfrac{2}{\quad \frac{\pi}{2}\quad }\implies \cfrac{4}{\pi }$
