If g(x) = -4x + 5, find g(-3x).
nignag [31]
Answer: 12x + 5

Explanation:

g(x) corresponds to x, so you plug -3x into x. That equals -4(-3x) + 5. Multiply to get 12x + 5. Because you can’t add a number with a variable to a whole number, that’s your answer. Hope this helps!

A 2-kg toy car accelerates from 0 to 5 m/s. How much work is done?
Viktor [21]

The work is the difference between the final and initial kinetic energy:

W=\Delta K = \dfrac{1}{2}mv^2_f-\dfrac{1}{2}mv^2_i=\dfrac{1}{2}m(v^2_f-v^2_i)

Substitute your values to get

W=\dfrac{1}{2}\cdot 2(25-0)=25
