the first choice has a negative 7 and the second choice has a negative 161 these are both negatives in different places which cause a different reaction
Continue the slop until it hits the y axis and that point will be your y intercept

Answer:

Paul will catch Fred after
at a distance
.
Step-by-step explanation:
Distance is represented by
and the time is represented by
. Here after
hours(when Fred started) the distance covered by Fred and Paul is same that is
.
For Fred:
time=
distance=
Speed

Paul:
Since Fred started 30 minutes earlier, so Paul's travel time will be 30 minutes less than that of Fred.
Time
Speed
Distance

Hence system of equation

Solution of this system of equations gives the time, when Paul will catch Fred and distance covered by each of them.

Time taken by Paul
Hence Paul will catch Fred after
at a distance
.
Answer:
3.1 seconds
Step-by-step explanation:
The time it will hit the ground is when the <em>height is equal to 0</em>. So we plug in 0 in h and solve the quadratic equation for t.

We will use the quadratic formula [
] to solve this.
a is -16
b is 40 , and
c is 30.
plugging these into the formula we get:

Since time cannot be negative, we take t = 3.1 as the value
So it will take 3.1 seconds to hit the ground (target)
