Factor out 0.1t (t + 16)
t + 16 = 0
Subtract 16 from both sides
t = -16
After 16 years the income begins to decline

Bond [772]

The graph of a non member's yearly cost is steeper, and also has a lower y-intercept. And the graph of a member's yearly cost starts higher, but is less steep.

Help me solve for A and B!

expeople1 [14]

Here we have one large triangle with two smaller triangles drawn inside. The two smaller triangles are similar.

Thus, a/12 = 12/16, or a/12 = 3/4, or 4a=36, or a = 9.

Find b in the same way: b/20 = 9/12 (and so on).

Answer: b) {-3, 0.5}

Step-by-step explanation:

The new equation is the original equation plus 6. Move the original graph UP 6 units. The solutions are where it crosses the x-axis.

$\text{Original equation:}\quad f(x)=\dfrac{15}{x}-\dfrac{9}{x^2}\\\\\\\text{New equation:}\quad\dfrac{15}{x}+6=\dfrac{9}{x^2}\\\\\\.\qquad \qquad f(x)= \dfrac{15}{x}-\dfrac{9}{x^2}+6$

+6 means it is a transformation UP 6 units.

Solutions are where it crosses the x-axis.

The curve now crosses the x-axis at x = -3 and x = 0.5.
