Hello there!

To find this, we must simplify this equation.

first, let's simplify the right side

-1 * x = -x

-1 * 5 = -5

Now, we have: y -3 = -x -5

Now we must add + 3 to each side to get rif of the negative three

now we have y = -x - 2

So, your answer is B.) y= -1x - 2

I hope my answer was of assistance!

Check all that apply. Pi/4<br> is the reference angle for:

Sergio039 [100]

Reference angle is the angle that is formed by the the terminal side of teh angle and the horizontal line or the x-axis. The reference angles of the different quadrants can be determined using the formula correspondingly:

Quadrant 1: RF = actual angle

Quadrant 2: RF = actual angle - 90 = actual angle - pi/2

Quadrant 3: RF = actual angle - 180 = actual angle - pi

Quadrant 4 : RF = actual angle - 270 = actual angle - 3/4 pi

The first thing to do is to determine the quadrants of each angle and then apply the formula:

a. 19 pi /4 = 855 deg = 2nd Q = 135 + 45 = 180 (correct)

b. 15 pi/4 = 675 deg = 4th Q = 315 + 45 = 360 (correct)

c. 7 pi/4 = 315 deg = 4th Q = 315 + 45 = 360 (correct)

d. 12 pi/4 = 540 deg = x axis = not correct

Answers are A, B and C.

How do I solve log(x) - log(6) = 2 ?

iris [78.8K]

$\bf \textit{Logarithm Cancellation Rules}
\\\\
log_a a^x = x\qquad \qquad \stackrel{\stackrel{\textit{we'll use this one}}{\downarrow }}{a^{log_a x}=x}
\\\\\\
\textit{Logarithm of rationals}
\\\\
log_a\left( \frac{x}{y}\right)\implies log_a(x)-log_a(y)
\\\\[-0.35em]
\rule{34em}{0.25pt}\\\\
log(x)-log(6)=2\implies log\left(\cfrac{x}{6} \right)=2\implies log_{10}\left(\cfrac{x}{6} \right)=2
\\\\\\
10^{log_{10}\left(\frac{x}{6} \right)}=10^2\implies \cfrac{x}{6}=10^2\implies x=600$
