Free points, solve 4b+5b=8b-1+3b+15?

vazorg [7]

Answer: Hi!

First, we should combine like terms:

4b + 5b = 8b − 1 +3b + 15 =

9b = 11b + 14

Now, we should subtract 11b from both sides.

-2b = 14

Now, we should divide both sides by -2.

b = -7

Hope this helps!

Prove that Tan x + Cos x = 1 /Sin x .Cos x

Anit [1.1K]

Answer:

tanx + cotx = $\frac{1}{sinxcosx}$

Step-by-step explanation:

<u><em>Explanation</em></u>

Take R.H.S = $\frac{1}{sinxcosx}$

= $\frac{sin^{2}x+cos^{2}x }{sinxcosx}$

= $\frac{sin^{2}x }{sinx cosx} + \frac{cos^{2} x}{sinxcosx}$

= $\frac{sinx}{cosx} + \frac{cosx}{sinx}$

= tanx + cotx

tanx + cotx = $\frac{1}{sinxcosx}$
