Answer:
D
Step-by-step explanation:
add them together
sub B = (x,y)
midpoint= ( (x-2)/2, (y+2)/2 )
(x-2)/2=1 and (y+2)/2=0
x-2=2 and y+2=0
x=4 and y= -2
B= (4,-2)
Answer:
12.5 km/hr
Step-by-step explanation:
An hour is 60 minutes.
So 15km/72min = x km/60min
15*60 = 72*x
x = 12.5
Answer:
mean:B median:B mode:A
Step-by-step explanation:
A is the mode, since it has the highest amount of same values,
c=x
b=x+1
a=x+2
mean: 3x+3/3=x+1, which is B, so B is the mean,
B is also the median, since B values are in the middle
1. f(5)=-39
2. g(-2)= -21
4. f(7)=19
9. x=7
