Answer:
Hence the required equation of circle is
(x - 4)² + ( y - 1)² = 4
Step-by-step explanation:
The equation of a circle whose center (h, k) and radius r is given-
(x - h)² + (y - k)² = r²
Here given that-
Center = ( 4, 1) & r = 2
Equation of circle-
<em>( x - 4)² + ( y - 1)² = 2²</em>
<em>(x - 4)² + ( y - 1)² = 4</em>
<em>x² + 16 - 8 x + y² + 1 - 2 y = 4</em>
<em>x² + y² -8 x - 2 y + 13 = 0 </em>
Hence the required equation of circle is
(x - 4)² + ( y - 1)² = 4
0R
x² + y² - 8 x - 2 y + 13 = 0
Answer:
1260
Step-by-step explanation:
12/72 is 1/6 of the students going to the play
210 students go to play
210 times 6 is 1260
Answer:
y=-1/5x+6
Step-by-step explanation:
y-b=m(x-a)
×5) y-7=-1/5(x--5) (×5
5y-35=-1(x+5)
5y-35=-x-5
5y=-x+30
y=-1/5x+6
Answer:
can you give more details of the question being asked
Step-by-step explanation:
The expression for y in terms of "a" when value of x is doubled is 
<em><u>Solution:</u></em>
Given that,
y is directly proportional to 
Therefore,
Where "k" is the constant of proportionality
y = a for particular value of x
Therefore,
--------- eqn 1
We have to find when x is doubled
x is doubled means 2x
Let it be 
Hence we get,
--------- eqn 2
Substitute value of k from eqn 1, we get
Thus expression for y in terms of "a" when value of x is doubled is
