Equation for given circle. A(4,7) is at center top of circle and B(7,4) is at center right hand side
1 answer:
Note:
The equation for a circle with center at (h,k) and radius r is
(x-h)² + (y-k)² = r²
For the specified circle,
h=4, h=7.
From the diagram shown below, the radius, r, is determined from the Pythagorean Theorem as
r² = 3² + 3² = 18
Therefore the equation for the circle is
(x - 4)² + (y - 7)² = 18
Answer: (x - 4)² + (y - 7)² = 18

Hi! Your answer is q = -9
Please see an explanation for a better and clear understanding to your problem.
Any questions about my answer and explanation can be asked through comments! :)
Step-by-step explanation:
Since we want to solve for q-term. That means we are going to isolate q-term.
We can add 4 and 9 together.
Because we want to know the value of q. That means we have to isolate q-term by subtracting both sides by 13.
We are reaching to the final step where we divide the whole equation by 3.
Finally, the solution for this equation is q = -9. But what if you are not certain or sure about the answer? Let's check it out!
To check the answer, simply substitute q = -9 in the equation.
Notice that the equation is true for q = -9. Hence, we can conclude that the solution for this equation is q = -9.
Hope this helps!
