Hello :
<span>note :
an equation of the
circle Center at the w(a,b) and ridus : r is :
(x-a)² +(y-b)² = r²
in this exercice : </span><span>x²+y²-16x+6y+53=0
(</span>x²-16x) +( y²+6y ) +53 = 0
(x² -2(8)x +8² - 8²) +(y² +2(3)x -3²+3² ) +53=0
(x² -2(8)x +8²) - 8² +(y² +2(3)x +3²)-3² +53=0
(x-8)² +( y+3)² = 20
the center is : w(8,-3) and ridus : r = <span>√20</span>
5x - 5y > = 70...subtract 5x from both sides
-5y > = -5x + 70...divide by -5 on both sides, and change the inequality sign
y < = x - 14 <===
Answer:
Think about PEMDAS, Whatever is in parentheses you solve that first. (6-2) which will be 4, you'll do 7+65*4 and find your answer. And divide by 2 at the end.
Hope this help
Step-by-step explanation:
Congruency is made up of two factors:
1) they possess the same angles
2) they possess the same side lengths, pertaining to each angle.
Answer: D) 3 blocks west and 5 blocks south.
At first, it is 6 blocks west and 2 blocks south, then 3 blocks east and 3 blocks south. Whenever it is an opposing direction, subtraction is used, and when it's the same direction, addition is used.
For west: 6-3
For south:2+3
Therefore: 3 blocks west and 5 blocks south.
