We evaluate b^2 - 4ac. If the answer is positive, then there are two real solutions. If it is zero, there is one real solution. If it is negative, there are 2 complex solutions. In this equation, a = 1, b = 5, c = 7. Now we plug in the numbers.
Because this answer is positive, there are two real solutions.
Because this answer is positive, there are two real solutions.
Answer:
<em>The correct answer is First option</em>:
Step-by-step explanation:
We are given 4 equations:
Let us solve the first two:
Multiplying (2) with 10 and adding to (1):
So, approximately, value of x is -0.3.
Putting value of x in (2):
value of x is approximately -0.3 so y is approximately 1.4.
So, the solution is (–0.3, 1.4)
<em>The correct answer is First option</em>:
The above two equations have a solution <em>approximately (–0.3, 1.4).</em>
