4. Caroline gets into a car accident. She is reading a text message and not paying
attention to the road. She hits a parked car
while accelerating at a rate of 21 m/s2. If the
mass of her car is 25000 grams, how much
force did she hit the parked car with?

525,000 N

Step-by-step explanation:

Since Force is mass multiplied by acceleration, you have to create the equation 25000*21 m/s^2.

25000*21 = 525000

She hit the parked car with 525,000 Newtons of force.

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571

step-by-step explanation:

if you was gonna solve for a, a is a   < -12
