Answer:
x=-2
y=5
Step-by-step explanation:
x=28-6y
2x-3y=-19
(substitute the value of x)
2(28-6y)-3y=-19
y=5
x=28-6*5
x=-2
Answer:
Option D.
3 equations with 3 variables
Step-by-step explanation:
The coordinates of a point in space must necessarily have 3 components. One to describe the distance on the x axis, another to describe the distance on the y axis to the point, and a third to describe the distance on the z axis.
If we have three variables, then 3 equations are needed to solve the system. With less than 3 equations it would be impossible to solver the system.
Therefore the correct answer is option D.

6. Classify the angle as acute, right, obtuse, or straight.
A. obtuse
B. acute
C. straight
D. right
(THE ANSWER IS OBTUSE ANGLE)
An Obtuse Angle Is what your looking at right now. Its angle is bigger than 90 degree.
A Acute angle is lower than 90 degree which tends to make something looking like the “<” “>” sign.
And straight angle is just a straight line (No kidding)
A right angle is justs a L shape sign. The corner of the L 90 degree
