A. I would suggest including <em>all</em> units in your answer. Both answers are correct but the unit is also important.
average rate of change:
($750 - $350) / (2014 - 2010) = $400 / (4 years) = $100 per year
initial value:
$350
B. Take 2010 to be year 0. Then for year <em>x</em> = 0, the fee is <em>y</em> = $350.
If the fee increases at a rate of $100 per year, this means that when <em>x</em> = 1, <em>y</em> = $350 + $100 = $450. So the graph of the function that models the dog-walking fee is a line that passes through the points (0, 350) and (1, 450), adn the slope of this line is
(450 - 350) / (1 - 0) = 100/1 = 100
which is the same as the average rate of change.
Using the point-slope formula for a line, the equation you want is then
<em>y</em> - 350 = 100 (<em>x</em> - 0)
<em>y</em> - 350 = 100<em>x</em>
<em>y</em> = 100<em>x</em> + 350
740% = 7.4 = 7 4/10 reduces to 7 2/5
Answer:
x=7
Step-by-step explanation:
The two marked angles in the image are supplementary, so we can form the following equation:
2x-3=x+4
We can solve that equation to find <em>x</em>.
2x-3=x+4
2x=x+7
x=7

<u>P=28ft 6inches</u>
Step-by-step explanation:
First lets make. each side into inches.
Length. 9ft 10in = 118inches
Width. 4ft 5in= 53inches
P= 2l+2w
P=2(118)+2(53) P=236in+106in. or. P=19ft8in+ 8ft 10inches
P=342inches. or. P=28ft 6inches
