To find invers
1. solve for y
2. replace y with xinverse
so
x=4-4y+y^2
reorder right side
x=y^2-4y+4
factor right side
x=(y-2)^2
squaer root both sides
+/-√x=y-2
add 2 to both sides
2+/-√x=y
switch x and y
2+/-√y=xinverse
xinverse=2+√y or 2-√y
subtract 4 from both sides
Answer:
165 Students Have No Made Plans For Lunch.
Step-by-step explanation:
According To the Question,
- Given,On a school trip to a theme park, 4 busses each carry 70 students Then Total Number Of Students on a trip is 70×4=280 Students.

Answer:
Step-by-step explanation:
<u>Given</u>
<u>Converted to standard form</u>
- 8*10^-7 = 8*0.0000001 = 0.0000008
You need to change 17% to decimal by moving the decimal to the right by 2x
so you will get .17*800=136
