Answer:
11x^2+x-1
Step-by-step explanation:
To do so, just add the two polynomials together as such:
11x^2 +0x-5 plus
0x^2+1x-4 equals
11x^2+x-1
Answer:
f⁻¹(x) = x+2 / 3
Step-by-step explanation:
Given function is:
f(x) = 3x-2
We have to find the inverse of the given function.
Put y = f(x) in given function, we have
y =3x-2
Adding 2 to both sides of the above equation we have
y+2 = 3x-2+2
y+2 = 3x
Dividing by 3 to both sides of the above equation, we have
y+2 / 3 = 3x / 3
y+2 / 3 = x
Put x = f⁻¹(y) in the above equation we have
y+2 / 3 = f⁻¹(y)
Swapping equation we have
f⁻¹(y) = y+2 / 3
Replace y with x we have
f⁻¹(x) = x+2 / 3 which is the answer.
Answer:
20%
Step-by-step explanation:
To find the percent she gave away, find how much of 25 treats 5 is:
5/25 = 1/5 = 0.2
