11/13 reduce in lowest form
Answer:
choice A. Since 12 -8 = 4 not 5
Step-by-step explanation:
if we plug in x =6 for 2x -8 = 5
2*6 - 8 = 12 - 8 = 4 not 5
Try B. 3*6 + 7 = 18 + 7 = 25 = 25 true
Try C. 4*6 + 12 = 24 + 12 = 36 = 36 true
Try D. 6*6 - 6 = 36 - 6 = 30 = 30 True

Answer:
See below
Step-by-step explanation:
arrange to standard form (x-h)^2 + (y-k)^2 = r^2 h,k = center r = radius
x^2 - 4x + y^2 + 2y = 4 complete the square for 'x' and 'y'
(x-2)^2 - 4 + (y-1)^2 -1 = 4
(x-2)^2 + ( y-1)^2 = 4 + 4 + 1 = 9 '9' is equal to r^2 so r = 3
<u>center = 2,1 radius = 3 </u>
25% of 15 is the same as 15% of 25
25%=25/100
25% of 15=(25/100)15=(25*15)/100
15%=15/100
15% of 25=(15/100)25=(25*15)/100
Therefore:
25% of 15=15% of 25
because:
(25/100)15=(15/100)25
(25*15)/100=(25*15)/100
3.75=3.75
