There is 100 N pushing the box to the right and 10 N pushing the box to the left
since there is force being applied in opposite directions, the net force is found by subtracting the 2
100 - 10 = 90 N ( Net Force)
and because the higher force is pushing the box to the right, the direction will accelerate to the right.

The discriminant is part of the quadratic formula which is b²-4ac.
So, in this case,
b²-4ac = (-9)(-9) - 4(7)(-8) = 305
Answer:
sqrt(11)
Step-by-step explanation:
3^3+sqrt2^2=11
Answer:
y=-3/2x+3
Step-by-step explanation:
The slope is rise over run. It rises 3 and goes back -2 so the slope is -3/2 and it crosses the y-axis at 3 so the y-intercept is 3. The slope equation is y=mx+b.
Answer:
The answer to your question is 2 hours
Step-by-step explanation:
Data
Juan speed = 4 mi/h
Cathy speed = 7 mi/h
t = x
Formula
speed = distance/time
Solve for distance
distance = speed x time
d = s x t
Distance travelled by Juan
d = 4t
Distance travelled by Juan in 1.5 h
d = 4(1.5)
d = 6 mi
total distance d = 6 + 4t
Distance travelled by Cathy
d = vt
d = 7t
Equal both equations
6 + 4t = 7t
Solve for t
6 = 7t - 4t
6 = 3t
6/3 = t
2 = t
Cathy wll catch up with Juan in 2 hours
