Times both sides by -1
-8x=x²-20
add 8x both sides
0=x²+8x-20
factor
what 2 numbers multiply to get -20 and add to get 8
-2 and 10
0=(x-2)(x+10)
set to zero
x-2=0
x=2
x+10=0
x=-10
x intercepts at x=-10 and 2 or at the points
(-10,0) and (2,0)
Answer:
5 mph north
Step-by-step explanation:
The relative velocity of the truck with respect to the car is ...
relative velocity = truck velocity - car velocity
relative velocity = 42 mph north - 37 mph north
relative velocity = 5 mph north
Step-by-step explanation:
In that equation it tells you that your slope is 2/3. It also tells you that your y intercept is -4. (Remember slope is written in y=mx+b) So first you plot your y value. (Remember that y intercept is up and down and slope is rise/fall over run) So your first point should be located at -4. Now you can began putting in your slope. Since your slope is positive, go up two and go to the right 3 times (rise/run). That's how you graph your equation.
Answer:
