Answer:
D = -6, E = -8 , F = 0
Step-by-step explanation:
standard form = 
now, when circle passes through (3,-1);
⇒ 
⇒ 
...............( equation 1)
when circle passes through (-2,4);
⇒ 
⇒ 
...............( equation 2)
when circle passes through (6,8);
⇒ 
⇒ 
................( equation 3)
by solving these 3 equations , we get;
D = -6, E = -8, F = 0
hence,
standard form =
= 
Answer:
11
Step-by-step explanation:
15 - 4 = 11
b
a and d should not be considered bc it is not logically correct. c is eliminated because that may not always be the case. therefore it should be b.
Answer:
7.5/5 = 1.5
6/1.5 = 4
X = 4
I'm pretty sure it's right
You divide 22 by 10 (2.2) and then multiply that by 3 to get 30%, which is 6.6. Then, you divide 2.2 by 2 to get 1.1, which is 5%. After this you just add them up to get the answer as 7.7.
Also, if you have q calculator, you can do it the short way and do 22 × 0.35 = 7.7
