I’m not quite sure I understand but if your saying that -9 =x and -7 =y then the answer would be -59 so the equation wouldn’t be true I hoped I helped :)
For this case we have that each student takes 8 \ frac {3} {4} minutes to perform and play 3 songs. Then, we convert the mixed number to a fraction:

Thus, each student takes
minutes.
If there are 9 students in the recital then we have:
minutes.
Thus, the recital lasts at least 78.75 minutes.
Answer:
The recital lasts at least 78.75 minutes.
Answer:
The answer is x=−1247
Step-by-step explanation:
Let's solve your equation step-by-step.
1+39(12−44)=x
Step 1: Simplify both sides of the equation.
1+39(12−44)=x
1+−1248=x
(1+−1248)=x(Combine Like Terms)
−1247=x
−1247=x
Step 2: Flip the equation.
Answer: x=−1247
Answer:
(x + 2)² + (y - 1)² = 25

Circle Center Formula: (x - h)² + (y - k)² = r²
- <em>(h, k)</em> is center
- <em>r</em> is radius
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify variables</em>
<em>(h, k)</em> = (-2, 1)
<em>r</em> = 5
<u>Step 2: Find Equation</u>
- Substitute in variables [Circle Center Formula]: (x - -2)² + (y - 1)² = 5²
- Simplify: (x + 2)² + (y - 1)² = 25
