Answer:
2: For every gallon of gas purchased, $3.75 was paid.
Step-by-step explanation:
Both options 1 and 3 would require having a dot plotted at those points to be sure, and they're close but they're still approximations. And option 4 is irrelevant. However the point at (4,15) can be used to check option two: 15/4 = 3.75 , ie the price per gallon of gas.
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
Answer:
1.625
Step-by-step explanation:
The decimal of 5/8 is 0.625.
We can then add 1 to it, since it is a whole number
Therefore, we have 1 + 0.625 = 1.625
what are the expressions?
please put the expressions so that i can help you! c:
Answer:
$180
Step-by-step explanation:
The difference between 1/5 and 1/6 of the rental price is ...
1/5 - 1/6 = 6/30 -5/30 = 1/30 . . . of the rental price
If 1/30 of the rental price is $6, then the full rental price is $6 × 30 = $180.
The total rent of the car is $180.
