Answer:
They form right angles 90 degrees angles
Step-by-step explanation:
X² - 2x + y² + 6y - 6 = 0
x² - 2x + y² + 6y = 6
(x² - 2x + 1) + (y² + 6y + 9) = 6 + 1 + 9
(x - 1)² + (y + 3)² = 16
center: (h, k) = (x, y) = (1, -3)
radius: 4
Answer:
7-z
Step-by-step explanation:
<span>let's say, you have 2(x+5)=10
What you do is multiply the x and the 5 by 2 so it now looks like
2x+10=10
The act of multiplying the inside numbers by the number outside the parenthesis is the distributive property. Now using distributive property to remove grouping symbols is similar
</span>Lets say you have 18 + {2 + 3 (6 -1*2)} first you would multiply 2by1
= 18 + {2 + 3(6 - 2)} then subrtact 2 from 6
= 18 + {2 + 3(4)} then multiply 3by 4 take away () grouping signal
= 18 + {2 + 12} then add 2 and 12
= 18 + {14} then take away the last grouping signals
= 18 + 14 then add 18 and 14
= 32
