Answer:
Trend lines are lines used to approximate the general shape of a scatter plot. A positive trend line tells us the scatter plot has a positive correlation. A negative trend line tells us the scatter plot has a negative correlation.
Answer:
-4 square units
Step-by-step explanation:
a = l × b
x2 - 3x - 28 = (x +4)(×)
x2 - 3x - 28 = x2 + 4x
-3x - 28 - 4x = 0
-7x - 28 = 0
-7x = 28
x = -4
As always, the "unit rate" can be written two ways. You have not specified which one you want.
.. (30 lb)/(1/3 ac) = 90 lb/ac
.. (1/3 ac)/(30 lb) = (1/90) ac/lb
If the two linear equations have the same slope (and the SAME y-intercept), the equations represent the same line. Since a line intersects with itself everywhere, there will be an infinite number of solutions (intersecting everywhere.)
