Y = x² + 2x – 45
y = -3x + 5
-3x + 5 = x² + 2x – 45
x² + 5x – 50 = 0
x has two values 5 and -10
x = 5 => y = -10
x = -10 => y = 35
Good luck.
Answer:
2/9
Step-by-step explanation:
lets create a sample space
so
the pirates can be sold for $7 $6 or $9
p
6 7 9
under the sea can be sold for $6 $7 or $9
S
6, 7, 9
driving test can be sold for $6 $7 or $9
D
6, 7, 9
here are all the combinations:
p,6
p,7
p,9
s,6
s,7
s,9
d,6
d,7
d,9
since out of 9 combinations driving test is the only one that is not water related lets look at that. There are only 2 combinations of driving test which are less than or equal to $7, (d,7 and d,6) hence the probability of selling no water games for less than $7 is 2/9
