Answer:
<u> (x-1)^4 + (y-4)^2 = 25 </u>
Step-by-step explanation:
Center at 1,4 means the circle is of the form:
(x-1)^4 + (y-4)^2 = r^2
Find r^2 using distance formula from center to the given point
r ^2 = ( 8-4)^2 + (4-1)^2
r^2 = 16 +9 = 25
so you answer is <u> (x-4)^4 + (y-8)^2 = 25 </u>

42 inches^2
The formula to find the area of a triangle is (base x height)/2
So, 12 x 7 = 84
and 84 / 2 = 42
Answer: x = 2
y = 2
Step-by-step explanation:
The given system of equations is expressed as
y = x²- 3x + 4- - - - - - - - - - - - -1
x + y = 4- - - - - - - - - - - -2
We would the method of substitution by substituting equation 1 into equation 2. It becomes
x + x²- 3x + 4 = 4- - - - - - - - - - -3
x² + x - 3x + 4 = 4
x² - 2x + 4 = 4
Subtracting 4 from the left hand side and the right hand side of the equation, it becomes
x² - 2x + 4 - 4 = 4 - 4
x² - 2x = 0
Adding 2x to the left hand side and the right hand side of the equation, it becomes
x² - 2x + 2x = 0 + 2x
x² = 2x
Dividing the left hand side and the right hand side of the equation by x, it becomes
x²/x = 2x/x
x = 2
Substituting x = 2 into equation 1, it becomes
y = 2²- 3 × 2 + 4
y = 4 - 6 + 4
y = 2
I would have said six hundred thousand but that cant be it.. sorry
