For two lines to be perpendicular, their slopes must be negative reciprocals of one another, mathematically:
m1*m2=-1, in this case our reference line has a slope of -3 so:
-3m=-1 divide both sides by -3
m=-1/-3
m=1/3
So the perpendicular line will have a slope of 1/3
Answer:
m = -18
Step-by-step explanation:
<u>Step 1: Combine like terms</u>
-8 = -m + 2m + 10
-8 = m + 10
<u>Step 2: Subtract 10 from both sides</u>
-8 - 10 = m + 10 - 10
-18 = m
Answer: m = -18
Answer:
x = 19.42
Step-by-step explanation:
8²+x²=21²
64+x²=441
-64 -64
x²=377
x=19.41648784
rounded is 19.42
20% if it will determine the pay of how much it is.
False. You get billed by the end of the month the money is “borrowed” money from the bank until you have to pay it all back, if it’s not paid on time you have to pay extra (interest). With debit card your money is taken out immediately.
