Step-by-step explanation:
Answer:
P(x) = -1.1x +49
Step-by-step explanation:
You are given the percentage in 2000 (for x=0) as 49, and told that its rate of change is -1.1 percent per year. So, with a slope of -1.1 and an intercept of 49, the slope-intercept form of the linear equation becomes ...
P(x) = -1.1x +49
_____
The slope-intercept form for slope m and y-intercept b is ...
y = mx + b
The answer is 3 yards.
There are 3 feet in a yard, so if we divide 9 (the length of the rope in feet) by 3, then we get the amount of yards in the rope: 9/3=3.
