You divide the difference in y-coordinates by the diffrence in x-coordinates. Or whatever the variables are.
Lets say the coordinates of the two points are (a,b) and (c,d). Then:
Rate of change is "rise/run" = (b - d)/(c - a) = (d - b)/(a - c)
<span>the equation is -16t^2+150t+50, the middle term being the upward velocity and the last term being the height it started at.
The vertex is at -150/-32=4.6875, and the height is 401.56 feet
Setting the equation equal to zero,
-16t^2+150t+50=0 or 16t^2-150t-50=0
t=(1/32) { 150 +/- sqrt (22500+3200)}, where sqrt (25700)=160.31
t=(1/32)310.31=9.697 sec or 9.7 seconds TIME TO LANDING

Answer: 20 = 5 × n ; n = 4
How do we know?
If the blue jar has 20 marbles, and the blue jar has 5 times as many as the red jar, and n is how many marbles are in the red jar then we can use this equation:
n × 5 = 20
So for the first portion of your question the answer would be: 20 = 5 × n
Now we have to solve for n:
20/5 = n
4 = n
So the answer to your second part would be: n = 4
In math, a term is defined as number separated by a plus or minus in this sentence.
So you have 5 terms:
