Answer:
it could be |-2|=2 or |2|=2
Step-by-step explanation:
its absolute values so any number in the doubles lines will be positive
Answer:
3/2 weeks
Step-by-step explanation:
The question: find the number of weeks you and your friend sells equal number of magazine
You = 2w + 9
Your friend = 6w + 3
Equate both equations
2w + 9 = 6w + 3
Collect like terms
2w - 6w = 3 - 9
- 4w = - 6
w = -6/-4
w = 3/2 weeks
There are shaded parts and total parts.
Write this as a fraction.
Simplify the fraction.
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
The question says the machine uses up m gallons of oil each hour on weekends.
This means that if the machine works for 24 hours each day, it implies that:
There are only two days on weekends i.e. Saturday and Sunday.
This means that if the amount of oil used in 1 day in the weekend is 24m, then we can say:
Saturday: oil used is 24m
Sunday: oil used is 24m
Total oil used during the weekend is:
