Answer:
Her weight is increase by 18 lbs over past five years and the slope is 3.6 lbs per year.
Step-by-step explanation:
Given information: Estelle weight is
At age 16 = 110 lbs
At age 21 = 128 ibs
Increase in her weight over the past 5 years is the difference of weight at age 21 and at age 16.
Increase in her weight over the past 5 years = 128 - 110 = 18
Her weight is increase by 18 lbs over past five years.
Let x=age and y=weight, then the weight function passes through the points (16,110) and (21,128).
If a line passes through two points
and
, then the slope of the line is

Using the above formula we get



Therefore the slope is 3.6 lbs per year.
Answer:
3x-y= 27
Step-by-step explanation:
9x-3y=27
1/3(9x-3y=81)
hence 3x-y=27
Answer:
D. 914 feet
Step-by-step explanation:
We are given the distance that a person can see on a clear day from the upper observation platform of the Eiffel tower in Paris. We are then required to estimate the height of the upper observation platform using the formula;

Where d is the distance and h the height of the upper observation platform. The first step would be to solve for h, that is make h the subject of the formula in the above equation;
We multiply both sides of the equation by the reciprocal of 5/6 which is 6/5;

The next step is to eliminate the square root on the Left Hand Side of the equation by squaring both sides;

Given d is 25.2, h becomes;

To the nearest whole number, h becomes 914
The question is asking to calculate how fast is the water level rising when the water is 9 inches deep and base on the said question or problem, and in my own understanding and computation about the said problem, the speed of the rising of the water level is 24/63 feet per minute. I hope this would help
