Represent graphically each of the following relations: \( \begin{array}{llll}\text { (1) } x+y=2 & \text { (a) } x-y=3\end{array} \) Choose the correct answer from those given : \( \begin{array}{llll}\text { (a) If }(2,-5) \text { satisfies the relation: } 3 x-y+c=0 \text {, then } \mathrm{c}=\ldots \ldots \ldots \\ \text { (a) } 1 & \text { (b) }-1 & \text { (c) } 11 & \text { (d) }-11\end{array} \)

If \( f(x)=\left\{\begin{array}{ll}2 x-5 & \text { if }-2 \leq x \leq 4 \\ x^{3}-4 & \text { if } 4<x \leq 5\end{array}\right. \), find: (a) \( f(0) \), (b) \( f(1),(c) f(4) \), and \( (d) f(5) \). (a) \( f(0)=\square \) (b) \( f(1)=\square \) (c) \( f(4)=\square \) (d) \( f(5)=\square \)

-11) \( \frac{22^{4} \cdot 8^{4}}{121^{4} \cdot 4^{6}}= \)

\( 19 j-86 \geq 5 \) or \( 27 j-82 \leq 18 \)

4. Jug A contains 5 times as much water as Jug B. After some water is poured from Jug A to Jug B, there are 1860 ml of water in each jug. How much water is poured from Jug A to Jug B?

Solve for \( r \). \( 3^{r}+3^{3-r}=28 \)
