Answer:
Step-by-step explanation:
y = mx + b
slope m is found as the change in y over the change in x
as y decreases 3 units for a 3 unit increase in x, the slope is -3/3 = -1
The y intercept b is where the plot crosses the y axis, 4 units above the x axis
y = -1x + 4
or
y = 4 - x
Let, the number of student = x
Fraction of boys = 1 - 2/5 = 3/5
So, it would be: x * 3/5 = 1482
x = 1482*5 / 3
x = 7410/3
x = 2470
Thus, There are total 2470 students
Hope this helps!
Answer:
Piecewise functions (or piece-wise functions) are just what they are named: pieces of different functions (sub-functions) all on one graph. The easiest way to think of them is if you drew more than one function on a graph, and you just erased parts of the functions where they aren’t supposed to be (along the ’s); they are defined differently for different intervals of . So is defined differently for different values of ; we use the to look up what interval it’s in, so we can find out what the is supposed to be. Note that there is an e…

Answer:
$30.40
Step-by-step explanation:
Divide 19.00 by 5 to find the price per bag.
Price per bag = 3.80
Price * quantity = total
3.80 * 8 = 30.40
Answer:
Aplha=105
Step-by-step explanation:
The perpendicular looks like double the base hence that angle is 30 and the other triangle have equal perpendicular and base, that angle is 45. So alpha+30+45=180, alpha=105
