Answer: y = 1/2x + 1
Step-by-step explanation:
<u>Given </u><u>:</u><u>-</u>
- A Equation ,

<u>To </u><u>find</u><u> </u><u>:</u><u>-</u>
- The value of y at x = -2.
<u>Solution</u><u> </u><u>:</u><u>-</u>
The given equation is ,
Now on substituting x = -2 , we have,
Using the property of exponents as ,
We have ,
<u>Hence</u><u> the</u><u> </u><u>r</u><u>equired </u><u>answer </u><u>is </u><u>1</u><u>2</u><u>.</u>
4.4 lies between 4.3 and 4.5
Answer:
and
Step-by-step explanation:
We have to solve the given equation - 2x² + 3x - 9 = 0
To solve the equation given above we have to factorize the left-hand side of the equation.
But it can not be factorized. So, use the Sridhar Achaya formula.
Therefore,
and
So,
and
{Where
}
Therefore, the solutions are imaginary numbers. (Answer)
Note: The Sridhar Acharya Formula gives if ax² + bx + c = 0, then the roots of the equation are
and
.
