3 / 1½ = 2 cups of flour per teaspoon
2x = 5
divide both sides by 2 to isolate x
x = 2.5
You need 2.5 teaspoons of vanilla for 5 cups of flour.

Let x be the number of days and y represent miles driven.
Since it costs 25 per day, you multiply 25 by x.
25x
10 cents (otherwise known as .1 dollars) per mile, multiply .1 times y. Now add the two.
.1y
25x+.1y
The answer is <span>a.) 25x + 0.1y</span>.
Answer: To find the inverse of the function, we need to make x as a function of y and at the final step make a switch between x and y (i.e. make x as y and y as x)
y = x² + 4x + 4 ⇒⇒⇒ factor the quadratic equation
y = (x+2)(x+2)
y = (x+2)² ⇒⇒⇒ take the square root to both sides
√y = x+2
x = √y - 2 ⇒⇒⇒ x becomes a function of y
final step:
∴ y = √x - 2 ⇒⇒⇒ the inverse of the given function
So, as a conclusion:
f(x) = y = x² + 4x + 4 ⇒⇒⇒ the given function
f⁻¹(x) = y = √x - 2 ⇒⇒⇒ the inverse of the given function
Answer:
The more often your interest compounds, the more interest you'll earn on your investment. It's easy to see that money grows more quickly when it's earning compound interest than when it's earning simple interest
