Answer:
A
Step-by-step explanation:
if (x1,y1) and (x2,y2) are the extremities of diameter,then eq. of circle is
(x-x1)(x-x2)+(y-y1)(y-y2)=0
reqd. eq. is (x+1)(x-5)+(y+9)(y-1)=0
center is (2,-4)
r=√(2²+(-4)²-(-14))
=√(4+16+14)
=√(34)
eq. of circle is (x-2)²+(y+4)²=34
or
(x²-4x)+(y²+8y)=14
(x²-4x+4)+(y²+8y+16)=14+4+16
(x-2)²+(y+4)²=34

Step-by-step explanation:
bc it just is lolllllll
<h2>y = 252</h2>
Step-by-step explanation:
To find the value of y when z = 14 we must first find the relationship between them
The statement
y varies directly as z is written as
y = kz
where k is the constant of proportionality
when y = 180
z = 10
180 = 10k
Divide both sides by 10
k = 18
The formula for the variation is
y = 18z
When z = 14
y = 18(14)
<h3>y = 252</h3>

9_>x>_-1
- x would have to be less than or equal to 9, but greater than or equal to -1. the symbols for the greater than or equal to is the > with a line under it (in case you didn’t know) and same with the less than or equal to
Answer:
Yes
I hope this answers your question!
Step-by-step explanation:
How do you estimate a division problem?
You can use multiplication to check your division answer this way.
1) Do the division problem.
2) Multiply the quotient times the divisor.
3) If there is a remainder, add it to the multiplication product.
4) Compare this answer to the dividend. They should be the same number (630 = 630).
