Answer:

68.7

Step-by-step explanation:

We need only estimate (approximate) the value of f(x) at x = 5:

f(x)=6.87(2.5)(x – 1) → f(5)=6.87(2.5)(5 – 1).

Note that 2.5(4) = 10, so now we have (exactly) f(5)=6.87(10), which, in turn, is

equal to 68.7.

Assignment: $\bold{Solve \ Equation: \ 58=-2\left(m+4\right)+m}$

<><><><><>

Answer: $\boxed{\bold{m=-66}}$

<><><><><>

Explanation: $\downarrow\downarrow\downarrow$

<><><><><>

[ Step One ] Switch Sides

$\bold{-2\left(m+4\right)+m=58}$

[ Step Two ] Expand $\bold{-2\left(m+4\right)+m}$

$\bold{-m-8}$

[ Step Three ] Rewrite Equation

$\bold{-m-8=58}$

[ Step Four ] Add 8 To Both Sides

$\bold{-m-8+8=58+8}$

[ Step Five ] Simplify

$\bold{-m=66}$

[ Step Six ] Divide Both Sides By -1

$\bold{\frac{-m}{-1}=\frac{66}{-1}}$

[ Step Seven ] Simplify

$\bold{x=-66}$
