Answer:
the system of equation has infinite solution
Step-by-step explanation:
, 
Solve the first equation for x_2
Subtract 5x1 on both sides


Now substitute -5x1 on second equation



0=0
So the system of equation has infinite solution
The answer should be 84. I hope that helped
Question #5: The center of this ellipse is (4,2). The ellipse is vertically oriented. What is the distance (a) from the center (4,2) to the upper vertex of the ellipse? What is the distance (b) from the center (4,2) to the right hand vertex of the ellipse?
The equation of this ellipse is
(y-4)^2 (x-4)^2
--------- + ---------- = 1, where (a and b are determined above).
a^2 b^2
Answer:
m∠K = 36°
m∠L = 54°
m∠M = 90°
Step-by-step explanation:
A triangle's angles add up to 180 degrees. We will add together all the angles and set them equal to 180. Then, we will solve for x. Lastly, we will solve for the angle measurements.
-> The little "box" in angle M means that it is equal to 90°
90° + (2x + 42)° + (4x + 12)° = 180°
90° + 42° + 12° + 2x° + 4x°= 180°
144° + 6x°= 180°
6x° = 36°
x = 6°
[m∠K]
4x + 12
4(6) + 12
36°
[m∠L]
2x + 42
2(6) + 42
54°
Answer:
Your answer is B.
Step-by-step explanation:
4 x 2 = 8
I know this because 12 / 6 = 2.
Therefore, Sense it is divided by two, you multiply the 4 by 2.
