Answer:
x =28
Step-by-step explanation:
Divide the numbers
Combine multiplied terms into a single fraction
Eliminate fraction denominators
Simplify
Divide both sides of the equation by the same term
We know that
center (−1, 4) and <span>passes through the point (3, −5)
</span><span>the value for the radius is,
using the Distance Formula---------r=</span>√(4+5)²+(-1-3)²=√(9²+(-4)²
r=√97
<span>equation for a standard form for a circle
(x-h)</span>²+(y-k)²=r²
<span>the center is (h,k)-----------> (-1,4)
</span>(x+1)²+(y-4)²=(√97)²---------------> (x+1)²+(y-4)²=97
the answer is
(x+1)²+(y-4)²=97
It has no solutions. Hope it helps
Inverse, baseically
replace f(x) with y
switch all x and y
solve for y
replace y with f⁻¹(x)
f(x)=6(x+2)-3
replace with y
y=6(x+2)-3
switch x and y
x=6(y+2)-3
solve for y
x=6y+12-3
x=6y+9
minus 9
x-9=6y
divide 6
1/6x-3/2=y
replace
f⁻¹(x)=1/6x-3/2
when x=21
f⁻¹(21)=1/6(21)-3/2
f⁻¹(21)=21/6-3/2
f⁻¹(21)=21/6-9/6
f⁻¹(21)=12/6=
f⁻¹(21)=2
answer is f⁻¹(21)=2
inverse function is
f⁻¹(x)=1/6x+3/2
