Answer:42.5
Step-by-step explanation:
X would equal -3.5 or -7/2
306% of 25
= (306/100) * 25
= 3.06 * 25
= 76.5
Answer:
(x + 4)² + (y - 9)² = 25
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) = (- 4, 9) and r = 10 ÷ 2 = 5, thus
(x - (- 4))² + (y - 9)² = 5², that is
(x + 4)² + (y - 9)² = 25
