Name the types of the following triangles

Solve: \( -9 x-1=-8 x+15 \)

Write the empirical formula of at least four binary ionic compounds that could be formed from the following ions:

Graph the linear function by finding \( x \) - and \( y \)-intercepts. Then write the equation using function notation. \( x-y=-1 \)

Given the function \( f(x)=-4 x-8 \), find the following values. \( \begin{array}{lll}\text { a. } f(-2) & \text { b. } f(s) & \text { c. } f(-x)\end{array} \)

Consider the following function. \[ f(x)=\left\{\begin{array}{lll}x^{2}+x & \text { if } \quad x<-3 \\ 6 & \text { if } & x=-3 \\ 2 x-1 & \text { if } & x>-3\end{array}\right. \] Evaluate the given limits. If a limit does not exist, enter DNE. (a) \( \lim _{x \rightarrow-3^{-}} f(x)=\square \) (b) \( \lim _{x \rightarrow-3^{+}} f(x)=\square \) (c) \( \lim _{x \rightarrow-3} f(x)=\square \)
