the number of cases of water ir 15
Answer:
4.583
Step-by-step explanation:
Equation of a circle is:
(x − h)² + (y − k)² = r²
where (h, k) is the center of the circle and r is the radius.
x² + (y − 3)² = 21
The center of the circle is (0, 3), and the radius is √21, or approximately 4.583.
The given equation does not have any solution.
For given question,
We have been given an equation −5a + 5a + 9 = 8
We know that the like terms are those terms which have same variable to the same power.
Combine Like terms;
0 + 9 = 8
9 = 8
⇒ which is False.
This statement is false for any values of x
Therefore, the given equation does not have any solution.
