Answer:
(7, 0 )
Step-by-step explanation:
Given the 2 equations
y = - 2x + 14 → (1)
y = 2x - 14 → (2)
Since both equations express y in terms of x we can equate them
2x - 14 = - 2x + 14 ( add 2x to both sides )
4x - 14 = 14 ( add 14 to both sides )
4x = 28 ( divide both sides by 2 )
x = 7
Substitute x = 7 into (2) for corresponding value of y
y = (2 × 7) - 14 = 14 - 14 = 0
Solution is (7, 0 )
Answer:
ok!
Step-by-step explanation:
the mean is 8.125 and the median is 7
Answer:
it's valid true the cat is cute
There are three answers and they are: choice 2, choice 3, choice 5
======================================================
Further Explanation:
Choice 1 is false because the intersection of the altitudes of a triangle leads to the orthocenter.
----
Choice 2 is true because the three medians of any triangle always intersect at the centroid. A median is a line that goes from one vertex to the midpoint of the opposite side. In this case, we go from point E to the midpoint of side CD. The midpoint of CD is found by bisecting segment CD (see choice 5)
----
Choice 3 is true. This is effectively the same as choice 5 below. The "perpendicular" aspect does not matter.
----
Choice 4 is false. Following the steps mentioned here will create an altitude line (see choice 1)
----
Choice 5 is true. To bisect something is to cut it in half. Let's say that point F is the midpoint of line segment CD. This means that line segment EF is one of the three medians of triangle CDE.
