The answer would have to be 4x^2y
Answer: $129
Step-by-step explanation: First, you round 2.75 up to 3 and then you multiply by 43. Boom, $129.
The matching is given below.
- Doubling ⇒ 2
- Quadrupling ⇒ 4
- Tripling ⇒ 3
- Halving ⇒ 1/2
<h3>What is an exponent?</h3>
Let a be the initial value and x be the power of the exponent function and b be the increasing factor. The exponent is given as
y = a(b)ˣ
You are asked to write exponential equations from word problems.
We know that factor 2 represents doubling, factor 4 represents quadrupling, factor 3 represents tripling, and factor 1/2 represents halving.
Then the matching is given below.
- Doubling ⇒ 2
- Quadrupling ⇒ 4
- Tripling ⇒ 3
- Halving ⇒ 1/2
