Answer:  A

The y-intercept is 3, not -3, so answer C is eliminated

Choose a point that is clearly in the shaded area or one that is clearly in the unshaded region

I choose the point (0, 0) and substituted these values in the equation and since 0 < 3, A is the correct answer

What is the equation of this line

Answer:

y = -\frac{4}{3}x + 4

Step-by-step explanation:

Use the slope-intercept form to write the equation if the line of the graph given.

y = mx + b, where,

b = y-intercept, which is where the line cuts across the y-axis = 4.

m = slope = \frac{y_2 - y_1}{x_2 - x_1} = \frac{0 - 4}{3 - 0} = \frac{-4}{3}

Substitute m = ⁴/3 and b = 4, into the slope-intercept formula to get the equation of the line:

y = mx + b

y = -\frac{4}{3}x + 4

Well, it's the average amount of time, so add 26.1 + 24.3 + 32.8 + 18.2. That equals 101.4 seconds or 1 minute and 41.4 seconds.

This is the change in kinetic energy of a system in which a 16 kg object moving at 25 m/s slows to a velocity of 20 m/s.
Natalka [10]

The change in kinetic energy of the  system is 200 J

Kinetic energy is the energy that an object possesses as a result of its motion.

It is given by:

Kinetic energy = (1/2)m[v - u]²

Where m is the mass of the object, v is the final velocity and u is the initial velocity.

Given that m = 16 kg, v = 20 m/s, u = 25 m/s, hence:

Kinetic energy = (1/2) * 16 * (20 - 25)² = 200 J

The change in kinetic energy of the  system is 200 J
