The answer is marked with red colour.
Step-by-step explanation:
find slope first
38-8/-14-(-20) = 5
y = 5x + b
find y intercept by sub in any set value show as long as they are belongs together
8 = 5(-20) + b
8 = -100 + b
108 = b
y = 5x + 108
You want log √(9/25). Recognizing that √9 = 3 and that √25 = 5, we get
log 3/5, which by rules of logs comes out to log 3 - log 5.
To four decimal places:
log 3 - log 5 = 0.4771 - 0.6990, or -0.2218.
