Answer:
A
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
Given (h, k) = (0, - 7) and r = 11, then
(x - 0)² + (y - (- 7))² = 11², that is
x² + (y + 7)² = 121 → A
Answer:
1/4
Step-by-step explanation:
2/8 is 1/4 and 1/2 is 2/4, subtract and you get 1/4.
Change 5/3 to 15/9. Then add 15 + 17 and put it over 9. 32/9
Answer:
76%
Step-by-step explanation:
do the amount of correct answers divided by the total of questions asked.
Well evaluate means solve . so you just substitute the -18 in place of x you'll get -18-10/ 4
which is -28/4 = -7
