Step-by-step explanation:
46.75. I think. You multiply 5.5 x 8.5. Hope this helps!
Answer:
Step-by-step explanation:
On this one you would eliminate the ones that are negative or that go into a negative. Which would be A,C, and E. The rest that are left are zero or positive. B for example is a zero because eventually there will be no candle. D would be the same in some way, the students will eventually leave the school. Finally F, the temperature would be increasing.
Answer - B,D,F
Answer:
<u><em>The equation is y = (1/2)x + - 3.5</em></u>
Step-by-step explanation:
We look for an equation with the form y = mx + b, where m is the slope and b the y-intercept.
We're given the slope, (1/2) which we can use for m:
y = (1/2)x + b
We are told the line goes through (5,-1). We need a value of b that will move the line to include this point. Do that by substituting the values:
x = 5, and y= -1
y = (1/2)x + b
-1 = (1/2)*5 + b
-1 = (2.5) + b
- 3.5 = b
<u><em>The equation is y = (1/2)x + - 3.5</em></u>

Answer:
Day 7 - 8
Step-by-step explanation:
We can calculate the maximum work she did in each interval by finding the difference between the y axis limits for each day.
This is also observed by the steepness of the graph, which is steepest for the interval between 7- 8 hours .
From day 1 to day 2 she worked 3 hours
From day 4 to 5 she worked 0 hours
From day 7 to 8 she worked 6 hours
From 9 to 10 she worked zero hours.
Hence, the maximum work she did was from day 7 to 8
