Motion Along a Line The graphs in Exercises 105 and 106 show the position s = f(t) of an object moving up and down on a coordi-
nate line. (a) When is the object moving away from the origin?
Toward the origin? At approximately what times is the (b) velocity
equal to zero? (c) Acceleration equal to zero? (d) When is the accel-
eration positive? Negative?

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!
