Answer:
A) Horsepower is the independent variable
D) The scatter plot shows a negative correlation
Step-by-step explanation:
Independent variable goes on the x-axis, it does not depend on another.
In this case, horsepower is the independent variable.
Negative correlation is a relationship between two variables in which one variable increases as the other decreases.
In this case, the scatter plot shows a negative correlation.
This is in slope-intercept form which is y=mx+b
where m is the slope and b is the intercept
in this equation -7 is m
The correct answer is -7
I really don't know how toowrk it out on paper, I'm afraid. I just looked at it, and somehow knew that the answers are 7 and 9.
Answer:
2x^2+7x+3
Step-by-step explanation:
(2x+1)(x+3)
2x^2+x+6x+3
2x^2+7x+3
Answer:
14
Step-by-step explanation:
put -2 where x is
f(x)=-x^2-9x
f(-2)= -(-2)^2 -9(-2)
f(-2)= -4 + 18
f(-2)= 14
