Answer:
[tex]\huge\boxed{N}[/tex]
Step-by-step explanation:
In order to find the midpoint of LQ, we need to find how long it is.
We can do this by finding the distance between L (-4) and Q (8).
From -4 to 0, it's 4.
From 0 to 8, it's 8.
So the total distance is [tex]8+4=12[/tex].
The midpoint of 12 units will be 6 units past L. We know that L is -4 so let's add 6 to it.
[tex]-4 + 6 = 2[/tex]
N is located at 2, so N is the midpoint of LQ.

What is the solution of this equation? 7y -4 = 9y +13 -4y
Answer:
y = 8.5
Step-by-step explanation:
7y - 4 = 9y +13 - 4y
First arrange to combine like terms.
7y - 4 = 9y - 4y + 13
7y - 4 = 5y + 13 Subtract 5y from each side
7y - 5y - 4 = 5y - 5y + 13
7y - 5y - 4 = 13
2y - 4 = 13 Add 4 to each side
2y - 4 + 4 = 13 + 4
2y = 13 + 4
2y = 17 Divide each side by 2
2y/2 = 17/2
y = 17/2 or 8[tex]\frac{1}{2}[/tex] or 8.5
How do you solve for x and y in this matrix equation?
Answer:
Hi!
I might be able to help you!
The Matrix Solution
It means that we can find the values of x, y and z (the X matrix) by multiplying the inverse of the A matrix by the B matrix.
The matrix method is similar to the method of Elimination as but is a lot cleaner than the elimination method. Solving systems of equations by Matrix Method involves expressing the system of equations in form of a matrix and then reducing that matrix into what is known as Row Echelon Form.

An egg is dropped from a height of 90 ft. If acceleration due to gravity is –16 ft/s2 and initial velocity is 0 ft/s, approximately how long will it take for the egg to reach the ground? h(t) = at2 + vt + h0 1.9 s 2.4 s 9.7 s 40.7 s
Answer:
B
Step-by-step explanation:
I answered it on edge
2.45 seconds will it take for the egg to reach the ground.
What is height?Height can be defined the vertical distance from the top to the base of the object.
Given
Height h(t) = 90 ft
Acceleration due to gravity a = -16 ft/[tex]s^{2}[/tex]
Initial velocity v = 0
[tex]h_{0}[/tex] = 0
[tex]h(t) = at^{2} +vt+h_{0}[/tex]
90 = 16[tex]t^{2}[/tex] + 0
90 = 16[tex]t^{2}[/tex]
[tex]t^{2} = \frac{90}{16}[/tex]
[tex]t^{2}=5.625[/tex]
t = [tex]\sqrt{5.625}[/tex]
t = 2.45
Hence, 2.45 seconds will it take for the egg to reach the ground.

If EC bisects BED, find m BED.
A. 128°
B. 130°
C. 134°
D. 136°
Answer:
19x+22
Step-by-step explanation:
Answer:
D. 136°
Step-by-step explanation:
[tex]\because \overrightarrow{EC} \:bisects \: \angle BED. \\
\therefore m\angle BEC = m\angle DEC\\
\therefore (11x+2)\degree = (8x+20)\degree \\
\therefore 11x + 2 = 8x + 20\\
\therefore 11x - 8x = 20-2\\
\therefore 3x = 18\\
\therefore x = \frac{18}{3}\\
\therefore x = 6\\\\
\because m\angle BED= m\angle BEC + m\angle DEC\\
\therefore m\angle BED= (11x+2)\degree + (8x+20)\degree\\
\therefore m\angle BED= (19x+22)\degree \\
\therefore m\angle BED= (19\times 6+22)\degree \\
\therefore m\angle BED= (114+22)\degree \\
