Answer: f(3) = 14
Concept:
Here, we need to understand the idea of evaluation.
When encountering questions that gave you an expression with variables, then stated: "If x = a, y = b, z = c" (a, b, c are all constants), this means you should substitute the value given for each variable back to the expression.
Solve:
<u>Given function</u>
f(x) = 4x + 2
<u>Substitute value of the x into the expression</u>
f(3) = 4(3) + 2
<u>Simplify by multiplication</u>
f(3) = 12 + 2
<u>Simplify by addition</u>
f(3) =

Answer:
<h2>C. 0.05 +0.1y = 0.12 + 0.06y</h2>
Step-by-step explanation:
According to the problem, both expression are equal because they have the same amount of mercury.
When the problem specifies an initial value, this means that value is not with the variable, because is an initial constant. When the problem specifies a rate, this is a coefficient of the variable, which expresses time (years.)
So, 0.05 parts per billion with a rate of 0.1 means: 0.05 + 0.1y, because the ratio is rising, that means is positive.
Similarly, 0.12 parts per billion with a rate of 0.06 means: 0.12 + 0.06y, because the ratio is also increasing, is positive.
Therefore, the right answer is C.
