Answer:
(-6,9,-3)
Step-by-step explanation:
-3x -y +z=6
-3x-y+3z =0
x-3z =3
Multiply the second equation by -1
-1 *(-3x-y+3z) =0*-1
3x +y -3z =0
Add this to the first equation
-3x -y +z=6
3x +y -3z =0
----------------------
0 + 0 + -2z = 6
Divide by -2
-2z/-2 = 6/-2
z = 6/-2
z=-3
Take the third equation to find x
x-3z=3
x-3(-3) = 3
x+9=3
Subtract 9 from each side
x+9-9 =3-9
x=-6
Now we need to find y
3x +y -3z =0
3(-6) +y -3(-3) =0
-18 +y +9=0
-9+y =0
Add 9 to each side
-9+9+y = 0+9
y=9
(-6,9,-3)
Answer:
Okay so number 3 is either undefined or Zero. I always forget which is which.
Step-by-step explanation:
But for 1 and 2 use your solution m=rise/run. Or you could count the ways down, like say, for number 1 it runs over 3 from a point and goes up till the next point. I hope this helps.
Answer:
10x + 5
Step-by-step explanation:
x = some number
10x = 10 multiplied by 'x'
10x+5 = five more than 10 multiplied by some number
Based on the information given, the bisected angle, quadrilateral, and congruent angles will be explained.
<h3>How to illustrate the information?</h3>
It should be noted that a quadrilateral simply means a closed shape that has four sides and four angles. These include square, rectangle, parallelogram, etc.
A bisected angle simply illustrates a line that splits an angle onto two equal angles.
Congruent segments are the segments that have the same length.
The diagrams are attached accordingly.
