Given



--- inverse
Required

For two functions f(x) and g(x) where f(x) and g(x)are inverse;

So, by comparison:

Answer:
Point T is the right angle of the triangle, so RTS = 90 degrees
8x + 18 = 90 (degrees)
8x = 72
x = 9 degrees
Step-by-step explanation:
I got 8(2a+3b) for the answer

Step-by-step explanation:
Answer:
The length of QS and TV is 8 units
Step-by-step explanation:
we know that
If triangle QRS is congruent with triangle TUV
then
QS=TV
QR=TU
RS=UV
In this problem
we have
QS=3v+2
TV=7v-6
so
QS=TV
3v+2=7v-6
Solve for v
7v-3v=2+6
4v=8
v=2
<em>Find the length of QS</em>
substitute the value of v
QS=3(2)+2=8 units
so
TS=8 units
