Answer:
(1, -2) Option A in your list of possible answers
See attached image.
Step-by-step explanation:
We need to graph the lines by using a couple of points on the plane for each equation.
For example:
the points (0, -3) and (3, 0) for the line y = x - 3
and the points (0, 1) and (-1, 4) for the line y = - 3 x + 1
Please see the lines in the attached image, and notice that they intersect at the point (1, -2), which gives you the solution for the system.
The average income for the household that is surveyed should represent the sample data is not relevant.
The information that should be considered as follows:
- The level of the income of the household represents the parameter of the population.
- The total income for the household that is surveyed represents the statistics of the sample.
- The household i.e. surveyed is relevant for the sample of the total population that lives in the zip code.
Therefore we can conclude that the average income for the household that is surveyed should represent the sample data is not relevant.

Answer:
The function is increasing for all real values of x where
x < –4.
Step-by-step explanation:
we have

This is a vertical parabola open downward (the leading coefficient is negative)
The vertex (h,k) represent a maximum
The roots of the function (or x-intercepts) are x=-6 and x=-2
The x-coordinate of the vertex is the midpoint of the roots
so

The y-coordinate of the vertex is
substitute the x-coordinate of the vertex in the quadratic equation



The vertex is the point (-4,4)
The function is increasing in the interval (-∞,-4)
The function is decreasing in the interval (-4,∞)
Speed is given by the formula:
speed=distance/ time
this implies that when we rewrite the above formula for distance we shall have:
distance=speed*time
from our question:
speed=60 mph
time=3 1/2 hours=3.5 hours
thus
distance=60x3.5
=210 miles
the answer is 210 miles
