Answer:
Equation of line: y=3x-18
Step-by-step explanation:
Point: (4,-6) and slope = 3
y=3x-18
F^-1(x) = sqrt 2(-5+x)/2, - sqrt 2(-5+x)/2
Answer: 9x+4=50
Step-by-step explanation:
In this case, we're looking at how many you can buy, not how many CD's you own.
Seca(1-sina)(seca+tana)=1
Left hand side
=(1-sina) (seca +tana) / cosa
=seca +tana - sinaseca - sinatan / cosa
=seca + tana -tana -(sin^2a/cosa) / cosa
=(1/cosa - sin^2a/cosa) / cosa
= (1-sin^2a / cosa) / cosa
= (1-sin^2a)/ (cos^2a)
=1 (verified)
Answer:
Depositing means that you added 50$ to your account. This means that you account increased by an amount of 50.
The integer describing this is +50.
Then, withdrawing means that you took money from the account. This means that your account decreased by an amount of 20.
