When this happens... The system of Equations has an Infinite Number of solutions.
A IS YOUR ANSWER
5.
A system of Equations has no solution when the graph of the system are PARALLEL LINES.
OPTION D IS YOUR ANSWER.
Answer:
Set up your height equation, then factor or use quadratic formula to find when h(t)=0
Step-by-step explanation:
Your equation will be -16t^2+vt +h where v is the initial velocity and h is the starting height. Now either factor or quadratic equation, whichever is easier for you.
Remember that the ball is on the ground when h(t)=0 since that is the height. There will be two zeros, one is a negative number so would be before you kicked the ball, the other one will be when the ball comes back down.
Substituting x = 3 into the first expression:
-4(3) - 8 = -12 - 8 = -20
Substituting x = 3 into the second expression:
-2(3 + 1) - 2(3 + 3) = -2(4) - 2(6) = -8 - 12 = -20
Y=mx+b
m=slope
b=y intercept, aka where the line crosses the y axis or where x=0
we can find the y axis by looking
it crosses the y axis at 4 units up
so
b=4
y=mx+4
we also se another point
(-5,0)
when x=-5, y=0
0=m(-5)+4
solve for m
0=m(-5)+4
subtract 4
-4=m(-5)
divide both sides by -5
-4/-5=4/5=m
equaiton is
y=4/5x+4
y=0.8x+4
