400+30+8 is how you put 438 in standard form.
The function that is graphed is...
B.) y = |x - 3| - 4
Since the lines "|" in the function make it a V shape.
And when you graph the one point where the the 2 lines meet it is.
(-3, -4)
So this answer is correct. :P
Good Luck! :)
To find the mean, add up all the test scores and divide by the number of tests:
524/10 = 52.4.
Well 3/8 is .375 but times 100 is 37.5%
Then 37.5% of 800 is 300
