f(-9) means x is -9
Replace x with -9 and solve:
2/3(-9) - 6
Simplify:
-6 - 6 = -12
f(-9) = -12
Answer:
angle 1=
°
Step-by-step explanation:
to find the angle of 1 you should know angle 2, what is angle 2?
angle
° and angle
are symetrical so they have the same value.
now that we know that angle 2 is equal to
°
then what is angle 1
if the whole line has an angle of
° and angle
°.
so the equation will be :

flip the equation to find
:

the angle 1 which we found in the given equation is 135
check if my answer is correct is :

my equation is correct

Answer:
The no. of variations in sign is 3
Step-by-step explanation:
Variation in sign occurs when every single time a negative product is produced by a pair of consecutive terms.
Therefore, the determination of the number of changes in sign in the given sequence is must.
Therefore, we take the product of the pair of consecutive terms as:
= - 3, variation in sign
= - 6, variation in sign
= 10, no sign variation
= - 20, variation in sign
= 24, no sign variation
