D. y= -2x-1
Hope this helps :))
Answer:
x-axis: (3, 0)
y-axis: (0, 16)
Quadrant 1: (36.7, 3.9)
Quadrant 2: (-1, 2)
Quadrant 3: (-5/8, -5 1/3)
Quadrant 4: (2, -12)
Step-by-step explanation:
x-axis: when y = 0 ⇒ (3, 0)
y-axis: when x = 0 ⇒ (0, 16)
Quadrant 1: when x > 0 and y > 0 ⇒ (36.7, 3.9)
Quadrant 2: when x < 0 and y > 0 ⇒ (-1, 2)
Quadrant 3: when x < 0 and y < 0 ⇒ (-5/8, -5 1/3)
Quadrant 4: when x > 0 and y < 0 ⇒ (2, -12)
Answer:
∠ WXY = 20°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ XYZ is an exterior angle of the triangle, thus
10x - 5 = 3x + 17 + 3x + 2
10x - 5 = 6x + 19 ( subtract 6x from both sides )
4x - 5 = 19 ( add 5 to both sides )
4x = 24 ( divide both sides by 4 )
x = 6
Thus
∠ WXY = 3x + 2 = 3(6) + 2 = 18 + 2 = 20°
