Answer:
you need 8 hours of training
The answer is -9 >(the same symbol I just don’t have it in my keyboard, sorry)k
-9>k
Answer:
Below
Step-by-step explanation:
sin(2x) = 2 ×cos(x)× sin(x)
● sin(x) = 2 × cos(x) × sin(x)
● 2 × cos(x) = 1
● cos (x) = 1/2
So we can deduce that:
● x = Pi/3 + 2*k*Pi
● or x = -Pi/3 + 2*k*Pi
K is an integer
The first equation must be multiplied by 18 and second equation must be multiplied by 8
<em><u>Solution:</u></em>
<em><u>Given system of equations are:</u></em>
--------- eqn 1
-------------- eqn 2
Multiply the second equation by 8 both sides to remove the fraction in the variable y

Multiply the first equation by 18 both sides to obtain the coefficient -3 in the variable y

Add eqn 3 and eqn 4

Thus the y-term is eliminated
Therefore, first equation must be multiplied by 18 and second equation must be multiplied by 8
