Answer: 2,2,3,3,3
The point-slope equation of a line that cointains the point (x1,y1) and has a slope of m is
y-y1=m(x-x1)
so
point (-2,3) and slope -4
y-3=-4(x-(-2))
y-3=-4(x+2) is da equation
Answer:
PQ R s parallelogram
< Q = < s = 114
< P = 180 _ 114 = 66
<2 = 66 / 2 = 33
< I = 114 / 2 = 5 7
< I + < 2 = 3 3 + 57 = 90
< ( STP ) = 90
TP I ST
3/4 = 6/8 = 9/12
4/5 = 8/10 = 12/15
Answer:
<em>19800 seconds, or 330 minutes, or 5 hours + 30 minutes</em>
Step-by-step explanation:
<u>Number Permutations</u>
We know the phone number has 7 digits, 4 of which are known by Mark. This leaves him 3 digits to guess with. We also know the last one is not zero. The number can be represented as
XXY
Where X can be any digit from 0 to 9 and Y can be any digit from 1 to 9. The first two can be combined in 10x10 ways, and the last one can be of 9 ways, this gives us 10x10x9 = 900 possible permutations.
If each possible number takes him 22 seconds, every possibility will need
22x900=19800 seconds, or 330 minutes, or 5 hours + 30 minutes
