\(2\) |
\(f(x) = 45x + 15\) |
\(68\) |
independent - months |
\(4x + 2.5y = 60\) |
\(6\) |
\(12x + y = 5\) |
\(f(x) = 6x + 20\) |
\(0\leq x \leq 2500\) |
\(\$1.60\) |
number of sent messages number of received messages |
\(80x + 100y = 1000\) |
\(J(t) = 6t\) \(S(t = 4.5t\) |
\(t \geq 0\) \(W(t) \geq 0\) |
\(\$330\) |
because of a constant rate of change |
\(y+1=-(x - 2)\) |
\(f(x) = 16x + 44\) |
\(f(x) = 0.25x + 0.35\) |
\(\$15\) |
\(W(t) = 4t + 2\) |
\(14\) |
\(0.02x + 0.05y = 50\) |
slope intercept form |
\(12\) |
\(0\leq t \leq 3\) \(0 \leq W(t) \leq 18\) \(0\leq t \leq 4\) \(0 \leq J(t) \leq 18\) |
JW printer is faster |
\(0 \leq f(x) \leq 1000\) |
\(5\) |
dependent - total cost |
\(f(x) = 50x\) |
