CURRENT OBfECTive Identify y-intercept in applications Question A group of students decides to make and sell cupcakes to raise money for their after-school group. To get started, they spend \( \$ 350 \) on all the supplies they will need. After determining how many cupcakes they can make with their supplies, they are happy with the profit they will earn by selling the cupcakes for \( \$ 2.50 \) each. What is the \( y \)-intercept in this situation? Do not include units in your answer. Somy thatis incorrect. Thy again?

13. There are about \( 4 \cdot 10^{5} \) known species of beetles. The number of known species of caddis flies is abo \( 10^{4} \). How many times more species of beetles are there than caddis flies?

Simplify the expression \[ (f+1)(2)= \]

\( 103 \Rightarrow \)

1. Calcula la tasa de variación (TV) y realiza su gráfica de acuerdo a \( f(x)=2 x^{2} * x-1 \) en \( [-2,3] \)

Simplify the expression. Write the answer as a power. \( \begin{array}{ll}\text { 1. } \frac{8^{12}}{8^{6}}=9^{12} & \text { 2. } \frac{3^{24}}{3^{15}} \\ \text { 3. } \frac{7^{14}}{7^{4}} & \text { 4. } \frac{3^{7}}{3^{4}} \\ \text { 5. } \frac{4^{12}}{4^{5}} & \text { 6. } \frac{9^{8}}{9^{3}} \\ \text { 7. } \frac{3^{4} \cdot 3^{5}}{3^{2} \cdot 3^{2}} & \text { 8. } \frac{8^{15}}{8^{7} \cdot 8} \\ \text { 9. } \frac{4^{5} \cdot 4^{9}}{4^{3} \cdot 4^{3}} & \text { 10. } \frac{9^{14} \cdot 9^{5}}{9^{7}} \\ \text { 11. } \frac{7^{3} \cdot 7^{9}}{7^{2} \cdot 7} & \text { 12. } \frac{3^{15} \cdot 3^{8}}{3^{9} \cdot 3^{6}}\end{array} \)
