A linear pair means the adjacent angles form a line...meaning they equal 180 degrees
Answer:
m=20
Step-by-step explanation:
hope this helps!! :)
You have to get X all by itself so you divide 20 and 30 which gives you a fraction. X= 20/30
Then = 2/3
Answer:
35 m/s
Step-by-step explanation:
Let gravitational acceleration g = 9.8m/s2. We can calculate the amount of time for the ball to fall vertically a distance of 1.6 m



This is also the time it takes for the ball to fly horizontally, assume constant horizontal speed, we can calculate the speed it takes to travel across 20m in 0.571s
v = 20 / 0.571 = 35 m/s
Y=mx+b
m=slope
b=yintercept
given
y=-2x+3 and
y=-4x-1
first equation is slope -2 and yintercept 3
second is slope -4 and yintercept -1
3rd option
