3.2 -9x+ 7.1 -3x
= (-9x -3x)+ (3.2+ 7.1) (combine like terms)
= -12x+ 10.3
The final answer is -12x+ 10.3~
Multiplying by 2, the next one would be 160
You have to remember that 1 equal 100% and that what you need to do is just to multiply the number by 100 and add at the end symbol % .
<span>.0015 * 100 = 0.15% </span>
the cosine is a cyclical function, so it cycles through from 0 all the way to the left and from 0 all the way to the right, nonstop, so its domain is (-∞, +∞), namely all real numbers.
