Homework I

Q.I

Solve the following simultaneous equations by graphical method. · Complete the following tables to get ordered pairs.

x-y=1
X 0 1 3 -2
Y -1 0 2 -3
(x,y) (0,-1) (1,0) (3,2) (-2,-3)

5x-3y=1
X 2 5 -1 -4
Y 3 8 -2 -7
(x,y) (2,3) (5,8) (-1,-2) (-4,-7)

· Plot the above ordered pairs on the same co-ordinate plane.
· Draw graphs of the equations.
· Note the co-ordinates of the point
of intersection of the two graphs. Write solution of these equations.

Q.II

Solve the above equations by method of elimination. Check your solution with the solution obtained by graphical method

Solutions

x-y=1 -(I)


5x+3y=1 -(II)


Multiplying both side of equation(I) by 5


5x-5y=5 -(III)


5x-3y=1 -(IV)


5x-5y=5


5x-3y=1


Eliminate like term


-5y=5+ 3y=1=-2y=4

y=4/-2

y=-2

Place y=-2 in equation(IV)


5x-3(-2)=1


5x+6=1


5x=-5


x=-5/5=-1


x=-1

Gene editing Gene editing: The future Introduction Gene editing is a rapidly evolving field with the potential to revolutionize medicine. By changing the DNA of cells, gene editing can be used to treat or even cure diseases, improve agricultural yields, and create new products. There are two main types of gene editing: CRISPR-Cas9: This is a relatively new gene editing technology that is very precise and efficient. CRISPR-Cas9 uses a protein called Cas9 to cut DNA at a specific location. This allows scientists to insert, delete, or replace genes. ZFNs and TALENs: These are older gene editing technologies that are not as precise as CRISPR-Cas9. However, they are still effective and are used in some clinical trials. Gene editing has the potential to treat or even cure a wide range of diseases, including: Cancer: Gene editing could be used to target and kill cancer cells. Inherited diseases: Gen

HTML Practical No.1 Aim: On a graph paper, draw a line parallel to the $X$- axis or $Y$- axis. Write coordinates of any four points on the line. Write how the equation of the line can be obtained from the coordinates. [Instead of parallel lines, lines passing through the origin or intersecting the $X$ or $Y$- axis can also be considered] Requirement: Graph paper,scale, eraser,pen,pencil Procedure: 1]A line equation $y=2$ is also written as $0x+y=2$,The graph of this line is parallel to $x$-axis;as for any value of $x,y$ is always. 2] Similarity equation $x=2$ is written as $x+0y=2$ and its graph is parallel to $y$-axis. $x$ 1 4 -3 $y$ 2 2 2 $(x,y)$ (1,2) (4,2) (-3,2) Conclusion: In this activity we have observed that x-axis and y-axis are parallel to each other Graph:
