Answer:
None of these
Step-by-step explanation:
Corresponding, alternate interior, and same side interior angles only occur in a set of parallel lines. In figure f, none of the lines are parallel. Straight angles are defined as angles that make up one side of the line, or 180 degrees, and as the picture clearly shows, this is not the case.
8:24 9:27 are some equal solutions.
Look at the x and y values and determine the relationship. For example, if the x values were 0, 1, 2, 3 and the y values were 1, 3, 5, and 7, you could see the slope equation was 2x+1. Another way you could do it is to input the values into a graphing calculator and it can determine the slope for u.
Answer:
(-3, 4, 6)
Step-by-step explanation:
-3x-4y+z=-1 equation 1
2x+y-z=-8 equation 2
x+8y-z=23 equation 2
Add equation 1 and 2
-3x-4y+z=-1
2x+y-z=-8
-----------------------
-x -3y = -9 equation 4
Add equation 1 and 3
-3x-4y+z=-1
x+8y-z=23
--------------------
-2x + 4y = 22 equation 5
multiply equation 4 by -2
2x + 6y = 18
Now add it with equation 5
2x + 6y = 18
-2x + 4y = 22
-----------------------
10y = 40
divide by 10 on both sides
y = 4
Plug in y = 4 in equation 4
-x -3y = -9
-x - 3(4) = -9
-x -12 = -9
add 12 on both sides
-x = 3
x=-3
plug in x=-3 and y =4 in any one of the original equation
-3x-4y+z=-1 equation 1
-3(-3) -4(4) +z= -1
9 -16 +z=-1
-7 + z= -1
add 7 on both sides
z = 6
