Atractor has a rear wheel with a 2-meter diameter and a front wheel with a 1-meter diameter. two points on the outer rims of the tires, a and b, are labeled in the picture. the height above the ground, in meters, of point a is a function of the distance, in meters, x, that the tractor moves forward. the graph of this function is shown. which function represents the height above the ground, in meters, of point b? a b(x)=0.5+cosx b b(x)=0.5+0.5cos(x2) c b(x)=0.5+0.5cosx d b(x)=0.5+0.5cos(2x)

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer

first one because it can't have a fraction in it

step-by-step explanation:

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
