Is there more to the problem?? Like how many points total in the quiz and stuff?
Angles in a triangle total 180°
180=128+5x+10+9x
180-128-10=5x+9x
42=14x
x=3
Answer:
Step-by-step explanation:
-1/2 ÷ 2(9+3)-4 - 3/4(8)
-0.5 ÷ 2(12)-4 - 3/4(8)
-0.5 ÷ 2(12)-4 - 6
-0.5 ÷ 24-4 - 6
-0.5 ÷ 14 =
Answer: -1/3
Step-by-step explanation:
Slope is the difference between the y coordinate points divided by the x coordinate points
We have (-1, 2) and (-4, 3)
Slope = 3 - 2/ -4 - (-1)
Slope = -1/3
Answer:
b
Step-by-step explanation:
u start at (0,9.5) and with every increasing x value the y value is decreasing by .5 units
