Final Exam - MTH 025 Please show your work for each problem. Partial credit will be given for correct work, even if the final answer is not correct. If your answer is incorrect and you have no work shown, the problem will be counted completely wrong. Therefore, it is in your best interest to show your work. CIRCLE your final answer. Solve the equation. 1) \( \frac{1}{5} a-\frac{1}{5}=-3 \) 2) \( (y-11)-(y+10)=8 y \)

\( \left. \begin{array} { c } { x + y + z = 6 } \\ { \left. \begin{array} { c } { 3 x - 2 y + 6 z = 11 } \\ { x + z = 7 } \end{array} \right. } \end{array} \right. \Rightarrow \left[ \begin{array} { c c c c } { 1 } & { 1 } & { 1 } & { 6 } \\ { 3 } & { - 2 } & { 6 } & { 1 } \\ { 1 } & { 0 } & { 1 } & { 7 } \end{array} \right] \)

The total of \( x \) and 78 is 24

3 Реши задачу. Один гончар заработал 1300 тенге, а другой, изготавливая такие же изделия, - 1950 тенге. Сколько изделий изготовил каждый из них, если первый изготовил на 2 изделия меньше, чем второй?

Find \( \sum_{i=3}^{7}\left(-\left(-\frac{1}{3}\right)^{i-1}\right) \) First write out the summation: Find the answer:

Factor the polynomial function \( f(x)=4 x^{3}+20 x^{2}+29 x+10 \) Note: Write \( \left(x-\frac{a}{b}\right) \) as \( (b x-a) \) The zeros are \( f(x)= \)
