Answer:

they are identical. proved below.

Step-by-step explanation:

formula: $sin(t)+sin(s) = 2sin(\frac{t+s}{2} )cos(\frac{t-s}{2} )$

using the formula to proof:

$sin9a+sin5a$

$2sin(\frac{9+5}{2})* cos(\frac{9-5}{2})$

$2sin7a * cos2a$

True. proved that they are identical.

What equation represents the line that passes through points (1.-5) and (3 -17)?

zzz [600]

ALL LINES CAN BE REPRESENTED IN THE FORM $f(x) = ax+b$ .

We know that:

$f(1) = -5 \implies a\cdot(1)+b = -5 \implies a+b = -5$

and

$f(3) = -17 \implies a\cdot(3) +b = -17 \implies 3a+b = 17$

Observe that:

$3a+b = 2a+a+b = 2a+(a+b)$

So:

$2a+(a+b) =-17$

But we know that $a+b = -5$ , so:

$2a+(a+b) =-17$

$2a+(-5) = -17$

$2a = -12$

$a = -6$

Since:

$a+b = -5$

$(-6)+b = -5$

$b = 1$

So the line is:

$f(x) = 1-6x$
