Answer:
The standard form is 
Step-by-step explanation:
The standard form of a linear equation can be written as

The given equation is

This equation is in the slope-intercept form.
To rewrite this in standard form, we must multiply through by the least common multiple which is 4.

We now add
to both sides of the equation to obtain,

This simplifies to

Hence the standard form is

The correct answer is A
Sin(A-B) = sinAcosB - cosAsinB
=<span>sin23cos27- cos23sin27</span>
= sin(23-27)
= sin(-4)
=-sin4
Well, there are 100 pennies in a dollar, and 10 dimes in a dollar. So, the ratio could be 10:100, or 1:10.
It would be nice If I could read it better. The answer is C if is says angle 3 and angle 5.
