^ This is the tenths place.
Since the number after it is less than 5, we round down.
So we round to:
6.9
-3y + 7 = y - 6(¹/₂y + 2)
-3y + 7 = y - 6(¹/₂y) - 6(2)
-3y + 7 = y - 3y - 12
-3y + 7 = -2y - 12
+ 3y + 3y
7 = y - 12
+ 12 + 12
19 = y
9x9+81
81/7= 81 over 7, or 11.6
Answer:
Option 3: take base-4 log each side
In case of multiple answers:
Options 3,4 & 5
Step-by-step explanation:
4^(x+3) = 18
Apply log4 both sides to being the power down
You can take log with any other base too.
In case of multiple answers, options 4 and 5 are also valid
C(12/15) because the other 3 all equal 0.666666666666667 but 12/15 equals 0.8
