Answer:
X= -1
Y= -3
Step-by-step explanation:
y=-5x-8
y=4x+1
-5x-8=4x+1
+5x. -1 +5x -1
-9=9x
-1=x
Y=4(-1)+1
-4+1
Y=-3
Answer:
i think -1/26
Step-by-step explanation:
(y2 - y1) / (x2 - x1)
(-15+16) /(-7-19)
1/-26
Answer:
64°; no
Step-by-step explanation:
Since XW bisects angle X, we have ...
angle YXZ = 2(angle WXY)
(4x +6) = 2(3x -5)
4x +6 = 6x -10 . . . eliminate parentheses
16 = 2x . . . . . . . . add 10-4x
8 = x
Then angle XZY = 8x° = 8·8° = 64°. The angle WXZ is (3x-5)° = (3·8-5)° = 19°, an angle that is not complementary to 64°. XW cannot form a right angle with YZ, so it is not an altitude.
Angle XZY is 64°, and XW is not an altitude.
