Cos9x - cos5x = -2sin2x.sin7x
sin17x - sin3x = 2sin7x.cos10x
so f(x) =
=
the answer is x= 8, and y=5
Answer:
{x | x∈ R, x < 2}
Step-by-step explanation:
Given
Open circle on 2
Arrow pointing left
Required
Determine the inequality
An open circle on 2 means represents either < or >
The arrow points to the left of -2 means that the number line represents numbers less than 2. i.e. < 2
Represent the numbers with x.
The inequality is: x < -2
Using proper notation, the inequality is: {x | x∈ R, x < 2}
Answer:
3
Step-by-step explanation:
to find this answer we will then have to do 5 x 2/3
since we our multiplying by a fraction we will then have to change the fraction to a decimal.
2/3 = 0.6
this will then give us the equation of 5 x 0.6
this will give us the sum of 3 jars that had were able to be filled woth marbles.
