100 points! must have correct answer and explain your work! evaluate the expression: v ⋅ w given the vectors: r = < 5, -5, -2> ; v = < 2, -8, -8> ; w = < -2, 6, -5> (it's an essay question so explain throughly.)

If the value of x increases by 5, how does the value of m(x + 3) change? a) it increases by 5m. b) it increases by 8m. c) it decreases by 5m. d) it decreases by 8m.

With this question substitute t=3 and t=5 to determine if the two expressions are equivalent. 4(t + 3) 4t+12 which statements are true? check all that apply. a. the value of both expressions when t =5 is 32. b. the two expressions are not equivalent. c. the value of both expressions when t=3 is 15. d. the value of both expressions when t=5 is 23. e. the two expressions are equivalent. f. the value of both expressions when t=3 is 24.

What is the value of f(x) = 2.2 for f(-2)?
