We know that
X²+y²=9 -------> X²+y²=3²
is the equation of a circle with center (0,0) and radius r=3 units
so
<span>the translation of four units to the right and three units down is equals to move the center (0,0)--------> (0+4,0-3)------> (4.-3)
the new center of the circle is (4,-3)
the new equation is
(x-4)</span>²+(y+3)²=3²
see the attached figure
Answer:
b = 30
Step-by-step explanation:
The sum of the 2 angles above the line will equal the angle below the line
3b + b - 15 = 2b + 45
4b - 15 = 2b + 45 ( subtract 2b from both sides )
2b - 15 = 45 ( add 15 to both sides )
2b = 60 ( divide both sides by 2 )
b = 30
Answer:
-3 >v
Step-by-step explanation:
3v-37>-2(8-5v)
Distribute
3v -37> -16 + 10v
Subtract 3 from each side
3v -3v -37> -16 + 10v-3v
-37 > -16 +7v
Add 16 to each side
-37 +16 > -16+16 +7v
-21 > 7v
Divide each side by 7
-21/7 >7v/7
-3 >v
Answer:
the third one: -15 <= 4x-3 < 5
