Answer:
y=-3x+5
Step-by-step explanation:
m= (-10-(-1))/(5-2) = -3
-1 = -3x2 + c
c=5
Gina surveyed students about their lunch time preference. Out of 50 students, 20 prefer eating lunch at 11:00am, 15 prefer eating at 11:15a.m., 10 prefer eating at 11:30a.m. , and 5 have no preference. Based on the information, what is the probability that a student chosen at random has no lunch time preference?
Answer:
6xy(x+2y)
Step-by-step explanation:
6x²y+12xy²
The GCF between 6 and 12 is 6. Factor out 6.
= 6(x²y+2xy²)
The GCF between x² and x is x. Factor out x.
= 6x(xy+2y²)
The GCF between y and y² is y. Factor out y.
= 6xy(x+2y)
Therefore, the GCF of the expression is 6xy and the factored expression is 6xy(x+2y).
I hope this helps!
Answer:
3072ft
Step-by-step explanation:
we have,
h(t)=-16t²+192t+2560
where
h -----> is the height in feet of the rock
t -----> the time in seconds
For t=8 seconds
substitute the value of t in the function and find the value of h
h(8)=-16(8)²+192(8)+2560
=3072ft
