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.
