Uhhhhhhhhhh i don’t really know
Answer:
X= 114
I don’t know what y is labeling so I won’t be able to help there sorry
Answer:
It would take 2,000 minutes
Step-by-step explanation:
2,000 times 5 is 10,000
We do the midpoint formula to find the center of the circle to get the left side of the equation.
Midpoint = [(X₁ + X₂) / 2 , (Y₁ + Y₂) / 2]
Now plug in:
[(8 + 4) / 2 , (- 6 - 2) / 2]
(12 / 2 , - 8 / 2)
(6, - 4)
The center of the circle is (6, -4)
Now we plug it into the equation of a circle:
(x - h)² + (y - k)² = r² where (h, k) is the center of the circle and r is the radius.
(x - 6)² + (y + 4)² = r² is the left side of the equation. This will eliminate options A and C
Now we do the distance formula using the center and an endpoint to get the radius. The formula for distance is:
√((X₂ - X₁)² + (Y₂ - Y₁)²)
We plug in using either of the endpoints.
√((4 - 6)² + (- 2 - (- 4))²)
√((-2)² + 2²)
√(4 + 4)
√8
√8 is your radius
(√8)² = 8
Your correct answer is (x - 6)² + (y + 4)² = 8, Option D
Answer:
Let x be the number of gallons of the 20% solution and let y be the number of gallons of the 5% solution.
Your system would be:
x+y=15
0.2x+0.05y=(0.13)(15)
Solve the system using either elimination or substitution method, or a combination of the two.
