Answer:
Step-by-step explanation:
The vertex would be the highest/lowest point so lets factor this first
when we factor we get
2(x^2+6x+8)
2(x+4) (x+2)
Using zero product property we find the 2 x values and x intercepts are
-4 and -2
the middle point of these points is -3
Substitute -3 for x and solve
2(-3+4) (-3+2)
2 * 1 * -1
2*-1
-2
(-3,-2) is the vertex
Answer:
(-2,-1)
Step-by-step explanation:
Midpoints are found when you do ([x(subscript A) + x(subscript B)]/2, [y(subscript A) + y(subscript B)]. Therefore your equation (for x of B) should look like this:
-4 = ([-6+x]/2)
After you solve for x, you should have gotten -2 for x.
Then you do the same for y:
2 = ([5+y]/2)
You should get -1. Your final answer should be (-2, -1)

Step-by-step explanation:
Answer:
C. Lincoln Forest is at sea level
Step-by-step explanation:
Elevation above sea level is indicated for several points in the table
Positive number indicates points <u>above</u>, negative number indicates points <u>below</u>, zero elevation indicated points <u>at </u>sea level
So, the answer for Lincoln Forest is:
- C. Lincoln Forest is at sea level
