Answer:
(10,6)
Step-by-step explanation:
let c be x2,y2
then apply mid point formula
x=(x1+x2)/2
y=(y1+y2)/2
If you wish to<u> mentally estimate</u> the <u>total cost</u> of items, <u>rounding </u>off the items to the<u> nearest half dollar</u>, then you have to consider all five items separately.
Five items cost $1.85, $.98, $3.49, $9.78, and $6.18.
1. $1.85≈$2;
2. $0.98≈$1;
3. $3.49≈$3.50;
4. $9.78≈$10;
5. $6.18≈$6.
Then the total cost is
$2 + $1 + $3.50 + $10 + $6 =$22.50.
Answer: correct choice is C
Answer:
Step-by-step explanation:
Complete the square
+ 2x - 13 = 0
+ 2x = 13
+ 2x + 
= 13 +1 (take 1/2 of the b term , the 2 )
+ 2x + 1 = 14
(x +1)^2 = 14
Answer:
One Solution
Step-by-step explanation:
