Answer:
(x + 2)² + (y + 9)² = 49
Step-by-step explanation:
Equation:
(x - h)² + (y - k)² = r²
(x - -2)² + (y - -9)² = 7²
(x + 2)² + (y + 9)² = 49
Dependent, because you're changing the probability
Answer:
4 times
Step-by-step explanation:
1 quart is equivalent to 32 fluid ounces.
If each eruption consumes 8 fluid ounces of vinegar. Assuming that the amount of vinegar required per eruption is constant, the number of times Tanvi can make her volcano erupt is:

Tanvi can make her volcano erupt 4 times with 1 quart of vinegar.
Answer:h
2x+1+3x+8./2=. 17
5x+9. = 17 x2
5x+9= 34
-9. -9
5x=25
Divide by 5
X=5
Step-by-step explanation:
X equals 90 because 360 /2=
