Slope of line perpendicular to ax+by=c is b/a
given
-2x-8y=18
slope of perpendicular is -8/-2=4
y=4x+b
find B
(4,5)
x=4,y=5
5=4(5)+b
5=20+b
minus 20
-15=b
y=4x-15
Answer:
$74,250
Step-by-step explanation:
495,000x0.6=297,000
297,000/4=74,250
Ok, so I'm pretty sure you get it by just dividing 168 by 182 to get 0.923 etc. Then if you multiply it by 100 then you get your grade. Which is about a <em>92.3%</em>. Hope this helps.
Answer: No
Step-by-step explanation:
You do 0.5 + 0.5 until you get it to 2.5 than count how many times you added 0.5 to get 2.5 it is equal to 5 so a week is 7 days so no it will not last them a week.
