Standard form for circle with radius r and center (h,k) is
(x-h)^2+(y-k)^2=r^2
r=36
center at -2,-7
(x-(-2))^2+(y-(-7))^2=36^2
(x+2)^2+(y+7)^2=1296
firts option
The value of 2a + 3b is 13
C. 5/15
First, change 3/7 to have the same denominator as 1/14.
3/7=6/14 because 7•2=14 (denominator) 3•2=6 (numerator)
Next, subtract 1/14 from 6/14.
6/14-1/14=5/14
15 + 6(x + 1)
Factor a 3 out of the expression.
3(5 + 2(x + 1))
Distribute the 2.
3(5 + 2x + 2)
Combine like terms.
3(7 + 2x)
3(7 + 2x) is your answer.
Answer:
17/50
Step-by-step explanation:
34% = 34/100 --> 34/100 * 1 = 34/100 * (1/2)/(1/2) = (34/2) / (100/2) = 17/50
