Yes it could be one........
Think of the equation of a linear function:
Recall y = mx + b for vertical shifts, we just add or subtract from 'b' and that will move the line up or down accordingly.. However, for horizontal shifts, we will need to add or subtract from 'x'. Note that the slope or 'm' stays the same for each type of shift.
Now that we know how the shifts occur, we might consider a different form of the equation for a linear function: y = a(x - h) + k here the 'a' is just our slope, 'k' is our original y intercept, and 'h' will represent the amount of horizontal shift.
So to get the desired transformations of a horizontal shift to the left of 8 and a vertical shift of down 3 from our original function y = x, we can make the following changes: y = (x + 8) - 3 Now you might be confused with how we got the 'x + 8'.. Let's consider values of 'h'. For positive values of h, the result will be a shift to the right and for negative values of h the result will be a shift to the left. So since we want a shift to the left we need to use a '-8' and when we substitute that into our new form, y = (x - h) + k you can see the sign change.
Now we can simplify of course and get the final equation: y = x + 5 or in function form f(x) = x + 5
You simply put 40 over a hundred and 55 over n (which is the number were trying to find) so you do cross multiplication. 55 times a hundred and after you get the answer. You divide it by 40 and should get 137.5.
1,000 pennies.
<span>If it was 7/10 full then after she removed 200 pennies it was 5/10 full. (5/10 = 1/2) </span>
<span>Therefore 2/10 is equal to 200 pennies. (7/10 - 5/10 = 2/10) </span>
<span>If 2/10 is 200 then 10/10 is 1000 pennies.</span>
One lap is .25 miles. so 9 laps would be 2.25 miles in 2.5 minutes. miles/minute is what we are trying to find. it is exactly what it looks like the amount of miles divided bye he amount of minutes, so 2.25/2.5 ur answer is 0.9 miles/minute
