Answer:
20
Step-by-step explanation:
if their ages total is 60 and gabrielle's is two times mikhail's age, that means that Mikhail would be twenty because their age times 2 would be 40 and 40 plus 20 is 60.
Answer:
A) g = 2m OR g -2m = 0
B) g + m = 60
Multiplying A) by -1
A) -g + 2m = 0 then adding this to B)
B) g + m = 60
3m = 60
Mikhail’s age = 20
Gabrielle's age = 40

Answer:
f(x) = + cosx or - cosx
Step-by-step explanation:
(2+tan^2x/sec^2x) -1 =(f(x))^2
=(( 1 + sec^2x)/sec^2x) -1
= 1 / sec^2x + 1 - 1
= 1 / sec^2x
= cos^2x
(f(x))^2 = cos^2x
f(x) = + cosx or - cosx
First you have to have the absolute value isolated so the 2 has to be divided. Then set up the two cases and solve.
No; we have
which reduces to
