Answer:

f(-2) = 11

Step-by-step explanation:

Given the function, f(x) = -3x + 5:

We can evaluate f(-2) by substituting -2 as the <em>input</em> (or x-value) for the function:

f(-2) = -3x + 5

f(-2) = -3(-2) + 5

f(-2) = 6 + 5

f(-2) = 11

Therefore, f(-2) = 11.

. The land area of Charlotte, NC is approximately 3 x 102 square miles.
lidiya [134]

Answer:

Option A

Step-by-step explanation:

Land area of Charlotte, NC = 3\times 10^2 square miles

Scale to be used,

1 square miles = 6.4\times 10^2 square acres

By this scale,

3\times 10^2 square miles = (6.4\times 10^2)\times(3.2\times 10^2) square acres

                                  = (6.4\times 3)\times 10^{2+2}

                                  = 19.2\times 10^4 square acres

                                  = 1.92\times 10^5 square acres

Therefore, Option A will be the correct option.
