Answer:
3
Step-by-step explanation:
Answer:
the system has no solutions
Step-by-step explanation:
the systems are shaded in different directions with no part of them intersecting
this means that there are no solutions
Answer:
0
Step-by-step explanation:
In the given expression, substitute -5 for x and 25 for y:
5|x|-y to the third power over x becomes
5|-5| - 25 25 - 25
------------------ = -------------- = 0
-5 -5
4)
12/16=21/b
multiply both sides by b
(12/16)b=21
now multiple both sides by (16/12)
b = 21 (16/12) =28
5)
rate is distance / time or time/distance
train travels 279 km per 1.5 hr =270/1.5
or
1.5 hr per 270 =1.5/27p
answer choice a and c matches that.
looking at choice C...270km/1.5hr=5hr/270km
looking at choice A.. 1.5hr/270km=5hr/k km
the units don't match for choice C so the
right answer is A
6)
1.5/270=5/k
multiply both sides by k
(1.5/270)k=21
now multiple both sides by (270/1.5)
k = (270/1.5)21= 900
7) 75 points per 6 game
75 points / 6 games
75/6=P/20
multiply both sides by 20
(75/6)20=P
P=250
