Answer:
x=-3 and y= -6
Step-by-step explanation:
we have
6=-4x+y and -5x-y = 21
6+4x=y we substitute y in the second equation
-5x-(6+4x)=21
-9x-6=21
-9x=27
x=-3
we substiture x in the second
-5(-3)-y =21
15-y=21
15-21=y
y=-6
Answer:
<h3>The answer is 10 units</h3>
Step-by-step explanation:
The distance between two points or a line segment can be found by using the formula
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(-4, 1) and (2, 9)
The length of segment AB is
We have the final answer as
<h3>10 units</h3>

Answer:
x = 14
Step-by-step explanation:
The sum of angles in a triangle is 180°:
∠O +∠P +∠Q = 180°
(2x -5)° +(3x -8)° +(10x -17)° = 180°
15x -30 = 180 . . . . . divide by °, collect terms
x -2 = 12 . . . . . . . . . divide by 15
x = 14 . . . . . . . . . . . .add 2
