Answer:
a) negative correlation b) Diagram C (I think) c) Diagram b
Step-by-step explanation:
a) Negative= line going dow
Positive= line going up
no correlation= no line
b) the dots are to close to each other which mean it has a string correlation.

Answer:
f(3) = 11
Step-by-step explanation:
To evaluate f(3), substitute x = 3 into f(x), that is
f(3) = 2(3) + 5 = 6 + 5 = 11
Charlotte's speed in meters per second is 2.5 meters per second.
What I did:
9 k per hour= (9/60)=per minute
9/60=0.15=15 m/m
0.15/60=0.025
0.025=2.5 m/s.
That is why Charlotte's speed in meters is 2.5 m/s.
The coefficient would be 1
before every variable, there is a one
So, x is equal to 1x
x+x is 2x
hope this helps:)
