(1) 3x+6y-12z=36
(2) x+2y-4z=12
(3) 4x+8y-16z=48
The first equation (1) is the second equation (2) multiplied by 3:
(2) x+2y-4z=12→3(x+2y-4z=12)→3x+6y-12z=36 (1)
The third equation (3) is the second equation (2) multiplied by 4:
(2) x+2y-4z=12→4(x+2y-4z=12)→4x+8y-16z=48 (3)
The equations are linearly dependent, Then the system of equations is dependent, and then consistent too.
Answer:
y=-1/2x+8
Step-by-step explanation:
Perpendicular of y=2x+6 is y=-1/2x
Substitute coordinates
4=-1/2(8)+8
y=-1/2x+8
The answer is letter A.
Solution:
180=2x+4+3x+16
180=5x+20
180-20=5x
160/5=5x/5
32=x
B=3x+16
=3(32)+16
=112 degrees
so the answer is 112
There is an 85 right in front of the x, red flag that you should look around there. The wording of the question says he gets 85 points per test, a perfect definition for our expression if x is the number of tests.
