(x - xc)² + (y - yc)² = r²
Where xc and yc are center coordinates
(x - (-4))² + (y - 3)² = 2²
x² + 2.x.4 + 4² + y² - 2.y.3 + 3² = 4
x² + 8x + 16 + y² - 6y + 9 = 4
x² + y² + 8x - 6y + 25 - 4 = 0
x² + y² + 8x - 6y + 21 = 0
Answer:
A. z = 2292.8 is your answer
Step-by-step explanation:
Isolate the variable (z). Note the equal sign, what you do to one side, you do to the other. Add 1092.8 to both sides
z - 1092.8 (+1092.8) = 1200 (+1092.8)
z = 1200 + 1092.8
z = 2292.8
A. z = 2292.8 is your answer

You need to find what 3 is if 5 is $520,000
$520,000 divided by 5 = 104,000
104,000 x 3 = 312,000
Therefore 3 is 312,000

Answer:
x=-9, y=5. (-9, 5).
Step-by-step explanation:
x-3y=-24
5x+8y=-5
--------------
x=-24+3y
5(-24+3y)+8y=-5
-120+15y+8y=-5
-120+23y=-5
23y=-5-(-120)
23y=-5+120
23y=115
y=115/23
y=5
x-3(5)=-24
x-15=-24
x=-24+15
x=-9

Answer:
60
Step-by-step explanation:
Gavin has 20/4 = 5 times as many sweets as his corresponding number of ratio units. The total number of ratio units is 4+5+3 = 12, so the total number of sweets is 5×12 = 60.
There are 60 sweets altogether.
_____
They are divided as ...
- Gavin: 20
- Colin: 25
- Dan: 15
