Answer:
x = -4
Step-by-step explanation:
2(x - 4) = 6x + 8
2x - 8 = 6x + 8
-4x - 8 = 8
-4x = 16
x = -4
Answer:
(x + 2)² + (y - 4)² = 16
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here (h, k ) = (- 2, 4 ) and r = 4 , then
(x - (- 2))² + (y - 4)² = 4² , that is
(x + 2)² + (y - 4)² = 16
Answer:
Step-by-step explanation:
a|c means that c=a*k k is some positive integer. We know that b|c so b| ak and (a,b)=1, so it must be b|k, i.e k=b*r, r is some positive integer number. Now we have that c=abr, so ab| c.
B) if x and x’ are both solution then we have that
mi | x-x’ for every i.
By a) we have that m1m2...mk| x-x’, so x and x’ are equal by mod od m1m2...mk.
