Answer:
x² + y² +10x -6y - 69 = 0
Step-by-step explanation:
We need to write the standard equation of circle with , centre (-5,3) and radius 10 unit . The Standard equation of the circle ⭕ is ,
=> ( x - (-5))² + (y -3)² = r²
=> ( x +5)² + (y-3)² = 10²
=> x² + 25 + 10x + y² +9-6y = 100
=> x² + y² +10x -6y + 31 = 100
=> x² + y² +10x -6y - 69 = 0
<h3>• Hence the equation of the circle is x² + y² +10x -6y - 69 = 0.</h3>
Answer:
Step-by-step explanation:
y= 3.50m + 35
y= 4.25m
4.25m = 3.50m + 35
.75m = 35
m = about 47 movies
-9-8(1+4h) = -17. We need to solve for h.
First, use the distributive property for 8(1+4h):
8(1+4h) = 8*1 + 8*4h = 8 + 32h
So -9-8(1+4h) = -17
-9 - (8+32h) = -17
-9 - 8 - 32h = -17
-17 - 32h = - 17
Add 17 on both sides to have the variables on a side and the numbers on the other:
-17 - 32h + 17 = -17 + 17
-32h = 0
divide both sides by -32 to get the variable h alone and its value on the other side:
(-32h)/-32 = 0/-32
h = 0.
So -9-8(1+4h) = -17 for h = 0.
You can recheck your answer (very important):
-9 - 8(1+4h) = -9 -8(1+4*0) = -9 - 8(1+0) = -9-8*1 = -9-8 = -17
The answer has been approved.
Hope this Helps! :)
Answer:
C
Step-by-step explanation:
So this is transformations
So this seems like it was rotated 180 degrees then dilated by a scale factor
The rule for 180 degrees is (-x,-y)
The rule for dilations is (2x,2y)
So the answer should be
C. (-2x,-2y)
Have a nice day
