Answer:
1/5 probability
Step-by-step explanation:
1) The total number of jelly beans is 20. This will be your denominator.
2) There are 4 red jelly beans. This is your numerator.
3) Using the numerator and denominator we have, your fraction is 4/20.
4) That can be simplified into 1/5.
7.96 / 6 = 1.33 <== unit rate
3x - 6x + 2 > 65
Combine like terms.
-3x + 2 > 65
Subtract 2 from both sides.
-3x > 62
Divide both sides by -3
x < -62/3
one way is to solve for the invers of the first function
remembe, to solve, replace f(x) or g(x) with y, switch x and y, solve for y and replace it with f⁻¹(x)
A.
f(x)=x/2+8
y=x/2+8
x=y/2+8
x-8=y/2
2x-16=y
f⁻¹(x)=2x-16
nope, not A
B.
f(x)=3x³+16
y=3x³+16
x=3y³+16
x-16=3y³
(x-16)/3=y³
∛((x-16)/3)=y
f⁻¹(x)=∛((x-16)/3)
nope, not the same
not B
C.
f(x)=18/x-9
y=18/x-9
x=18/y-9
x+9=18/y
y(x+9)=18
y=18/(x+9)
f⁻¹(x)=18/(x+9)
correct, the answer is C
answer is C
