Step-by-step explanation:
(secx-tanx)(secx+tanx)
=sec^2-tan^2
=1
Answer:
it looks great! i'd give you an a+
honestly I couldn't make that
Answer:
The answer is C so X is=16
I will try to solve your system of equations.
y=22;−10x+15y=−10
Step: Solvey=22for y:
Step: Substitute22foryin−10x+15y=−10:
−10x+15y=−10
−10x+(15)(22)=−10
−10x+330=−10(Simplify both sides of the equation)
−10x+330+−330=−10+−330(Add -330 to both sides)
−10x=−340
−10x
−10
=
−340
−10
(Divide both sides by -10)
x=34
Answer:
y=22 and x=34Answer:
