Answer:
x=-3/7 and y=_23/7
Step-by-step explanation:
y=-4x-5 and y=3x-2
using comparison method
-4x-5=3x-2
-4x-3x=-2+5
-7x=3
x=3/-7
substituting the value of x
y=3x-2
=3×(-3/7)-2
=-9/7-2
=-9-14/7
=-23/7
Answer:
(x - 5)² + (y + 7)² = 81
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) = (5, - 7) and r = 9, thus
(x - 5)² + (y - (- 7))² = 9², that is
(x - 5)² + (y + 7)² = 81 ← equation of circle
