1. find the speed of a car
the distance is 124 miles and the time is 2 hours
the speed is defined as distance / time, therefore
speed = 124/2 = 62 miles/hour
that is the speed
2.find the time from equation time = distance/speed, when the distance is 395 miles and the speed is 79 miles/hour, then
time = 395 miles / 79 miles/hour = 395/79
time = 5 hours
Answer:
x=3 x = -1
Step-by-step explanation:
f(x) = x^2 − 2x − 3
Set the function equal to zero
0 = x^2 − 2x − 3
Factor
What two numbers multiply to -3 and add to -2
-3 *1 = -3
-3+1 = -2
0 = (x-3)(x+1)
Using the zero product property
x-3 =0 x+1 =0
x=3 x = -1

Slope form - y2-y1/x2-x1
7-6/ 2-8
1/-6
Your slope is -6x
Hope this helps
