Answer: y = |x+3|-2
Step-by-step explanation:
The answer is the second one, y = |x+3|-2
It's similar to Parabola, |x+3|-2 is just like (x+3)^2-2, except about the graph. So (-3,-2)
Question 6
first multiply the numerator and
denominator by 9+(2)^1/2
Question 7
Step-by-step explanation:
x=2
y=0

Answer:
84 is the highest possible course average
Step-by-step explanation:
Total number of examinations = 5
Average = sum of scores in each examination/total number of examinations
Let the score for the last examination be x.
Average = (66+78+94+83+x)/5 = y
5y = 321+x
x = 5y -321
If y = 6, x = 5×6 -321 =-291.the student cannot score -291
If y = 80, x = 5×80 -321 =79.he can still score higher
If If y = 84, x = 5×84 -321 =99.This would be the highest possible course average after the last examination.
If y= 100
The average cannot be 100 as student cannot score 179(maximum score is 100)
Answer:
Step-by-step explanation:
Percent Error = | Actual Yield-Theoretical/ Theoretical Yield | *100%
Error= |-1/7|*100%= 14.29%
