Answer:
X= 1, Y= 4, Z= -2
Step-by-step explanation:
(3(6x-2y-3z=4)) + (-2(9x-3y+3z=-9))
Z=-2
Substitute in Z
(6x-2y+6=4) + (3x+2y-4z=7)
X=1
Substitute in Z and X
3+2y-4=7
Y=4
The slope formula is (y2 - y1)/(x2 - x1). It doesn't matter which one you use as x1 or x2 and long as you use the same order for the y's.
After plugging these 2 points in the formula, you get (24-4)/(5-1) = 20/4 = 5. Therefore, the slope is 5.

Answer:
r=-5
Step-by-step explanation:
-3=r-4/2-(-1) (plug into the slope formula)
-3=r-4/3 (solve the denominator)
-9=r-4 (multiply both sides by 3)
-5=r (add 4 to both sides)
Answer:
lines LO and LP intersect
Step-by-step explanation:
they touch at point L
Answer:
B. 24
Step-by-step explanation:
The way to find range is by putting the set from largest to smallest, then subtracting the highest number from the lowest. In this case, the highest number would be 31, and the lowest would be 7. So 31-7=24 which is your range. Hope this helps! (please give brainlist!) :)
