$2,653.60 would be the total cost with tax and the tax is $173.60
Answer:
Step-by-step explanation:
At first sight this equation has 3 terms. Multiply all 3 of them by 10 to remove the fractions:
4b + 13 = 4(b - 5)
Carrying out the multiplication, we get:
4b + 13 = 4b - 20
This can never be true (13 is never equal to -20), so this equation has NO SOLUTION.
Answer:
c

Answer:
The inverse is
f^-1(x) = (1/√2)x^¼
And it is a function
Step-by-step explanation:
Given f(x) = 4x^4
Let y = f(x), so that
y = 4x^4
Then dividing both sides by 4
x^4 = y/4
Taking the fourth root of both sides
x = (y/4)^¼
x = (1/√2)y^¼ = f^-1(y)
Put y = x
y = (1/√2)x^¼ = f^-1(x)
This is the inverse.
f^-1(x) is a function.
