\( 1 \leftarrow \quad \begin{array}{l}\text { Graph the equation and identify the } y \text {-intercept. } \\ y=\frac{3}{2} x+6\end{array} \)

Solve the following inequality. \( x^{2}-15 x+54>0 \) The solution is (Type your answer in interval notation. Use integers or fractions for any numbers in the expression. Type an exact answer, using radicals as needed.)

Last week, Dakota decided she wanted to make her own holiday cards. She purchased supplies and made her first batch. She plans to make even more today. The function \( C(t)= \) \( 7 t+11 \) represents the total number of cards she'll have after \( t \) hours of working on cards today. Complete the paragraph. Dakota started with \( \square \) cards. She will make \( \square \) cards per hour. After 2 hours of working today, she will have \( \square \) cards in all.

6. Find the solution. \( \quad 6 y-1=2(y+8) \)

Solve. Check your solution. \( 9 a+8+3 a=-5 \)

Which two equations below have a solution of \( x=-5 \) ?
