Marion is observing the velocity of a cyclist at different times. After four hours, the velocity of the cyclist is 14 km/h. After nine hours, the velocity of the cyclist is 4 km/h. Part A: Find the rate of change for the cyclist from hour 4 to hour 9. (2 points) Part B: Write an equation using the point-slope form equation that can be used to describe the velocity of the cyclist at different times. (4 points) Part B: Change your point-slope equation from part B to a slope-intercept equation. (4 points)

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)

answer: yes, since the line has a steeper rate of change than the exponential the y-values will be greater and they will only intersect one time.
