Answer: 109.5 km/ hr
Step-by-step explanation:
Distance = 73 km
Time = 40 minutes = 40/60 = 2/3 hours
Speed = Distance / time
= 73 / 2/3
= 73 x 3/2 = 219 / 2 = 109.5 km/hr
X + (-y) = -2.3 + ( - (-5.9) ) = -2.3 + 5.9 = 3.6
Answer:
The person above is correct
Step-by-step explanation:
Step-by-step explanation:
angle k equal to angle m ,,,
Paralell lines have same slopes
y=mx+b
m=slope
given
y=-3x-8
slope is -3
so we just have to have y=-3x+b
