Answer:
I'll set up the problem and you can do the calculation
Step-by-step explanation:
we need to complete the squares to get the equation in the general form:

where h = the x coordinate of the center
k = the y coordinate of the center
r = the radius
so looking at

we can see that if use -1 as the constant we have

doing the same for y

we can use -2 as the constant (basically you that the s
quare of the y coefficient )

so now we have to add or subtract the constant on the RHS to see what the square of the radius is according to the general form of the equation at the top
20 +1+4=25
Take the square root and you have the radius
Answer:
3x^3 + 3x^2 - 27x - 27
Step-by-step explanation:
Answer:
y = 3/4 x + 25/4
Step-by-step explanation:
just tried the numbers out with desmos (free online software
the 3/4 where guessedby intuition
(would indeed appreciate the brainliest if you appreciate the work)
Honestly I’m not for sure but I’m think it’s either a or b
Answer:
11/381
Step-by-step explanation:
Not sure what the ? after each number means but I'm going to assume they aren't there
so we need find the number of tokens in all which is
44+1414+66=1524
P(red)=44/1524 now reduce giving P(red)=11/381
