Sina - (cosa)(tanb)/cosa + (sina)(tanb)
sina ≡ (tana)(cosa)
(tana)(cosa) - (cosa)(tanb)/cosa + (tana)(cosa)(tanb)
= cosa(tana - tanb)/cosa(1 + tanatanb)
(cosas cancel out)
= (tana - tanb)/(1 + tanatanb) ≡ tan(a-b)

Step-by-step explanation:
Answer:
y=-4/5 x + 7
Step-by-step explanation:
Subtract 8 x by 8 x. Do not put 8 x under 10 y or 70.
Then divide 10 by all of the terms.
Then you have: y= 7 - 8/10 x
But then you have to flip 7 and - 8/10 x
And get y= -8/10 x + 7
Simplified is y= 4/5 x + 7
REMEMBER: y=m x + b
M= Slope
B= y-intercept
2.2=4
2.7=14
5-4+14-5=1+14-5=15-5=10
Good Luck!
