Depends on how much the quiz of your class are worth. The quizzes could represent only %50 of your grade and the rest might be homework
You will have to find 6% of 550.
As a proportion it will look like...
6/100=x/550
550*6=3300 3300/100=33
x=33
33 toys will be defective. Hope I was of assistance.
Step 1: 10 grpups of 23 = 230
Step 2: 6 groups of 23 = 138
Step 3: 10 + 6 = 16
Hi!
Switch up the variables:
y = -14x - 2.
x = -14y - 2.
Add 2 to both sides.
x + 2 = -14y - 2 + 2.
x + 2 = -14y.
Divide by -14 on both sides.
(x + 2) / -14 = -14y / -14.
(x + 2) / -14 = y.
Change the y to f^-1(x).
f^-1(x) = (x + 2) / -14.
Hopefully, this helps! =)
