Try to get all the x'es to the right side
Answer:
y = 1.5x
Step-by-step explanation:
We are to find the equation of the straight line
Using the coordinate (0, 0) and (200, 300)
Slope m = 300-0/200-0
m = 300/200
m = 1.5
Since the line pass through the origin, the y intercept is 0
Substitute m = 1.5 and b =0 into y = mx+b
y = 1.5x + 0
y = 1.5x
This gives the required equation
Ten thousand - 10,000
thousand literally just haves 1,000
if the twenty is before the three zeros, it would be 20,000 which is twenty thousand. its the same with other numbers. its super simple!
Answer: From what you wrote the I think the ball is drop
At time 0 you are 7 meters above ground
You basically just need to solve for
1.5 =7t-4.9t^2
by rearrange the equation you get
4.9t^2-7t+1.5=0
by using Quadratic Formula
t=1.166s
