5 log 3 + log 4 can be written as:
Answer:
Step-by-step explanation:
Find 3 ratios that are equivalent to the given ratio. 5/15
1 : 5 (0.2)
3/15 (0.2)
4 : 20 (0.2)
Siamone has $65.32 + DAN
Dan has CARLY - $37.50
CARLY = $127.75
Plug Carly into Dan's equation...
$127.75 - $37.50 = $90.20
DAN = $90.20
Plug Dan into Siamone's equation
$65.32 + $90.20 = $155.57
He has the same as well 6.5
You will need the point slope formula if you don't know it already which is x2-x1 over y2-y1. so in this case, it would be 1-(-1) over -4 -(2) which gives you 1 over 3 simplified and that is your slope. you are then going to substitute one of the point in the slope formula, y=mx+b. so let's say you go with the first point and substitute it, that will give you, 2=1/3(-1)+b and you would solve for b. after you figure out your equation, you multiply 1/3 by -1 to give you -1/3+b=2. Then you would add -1/3 to both sides to get b by itself. You would have b= 2+(-1/3). you with then calculate the difference to get b= 2 1/3 or b= 2.3.
