Answer:
9
Step-by-step explanation:
If you want to get $15 profit, You will need to paint 9 faces. You spent $12 on painting supplies so this is the explanation.
$3 x 9 = $27
$-12 + $27 = $15
That way, you earn $15.
First find equation
center is (h,k) then
(x-h)^2+(y-k)^2=r^2
given
(7,0) is center
(x-7)^2+y^2=r^2
also given (2,0)
(2-7)^2+0^2=r^2
(-5)^2=r^2
25=r^2
(x-7)^2+y^2=25 is equation
take derivitive of both sides, implicit differntiaton
2(x-7)+2y dy/dx=0
2(x-7)=-2y dy/dx
(7-x)/y=dy/dx
at (2,0)
(7-2)/0
undefined
that means the line is x=something
(2,0)
the equation is x=2
Answer:
x = 0
Step-by-step explanation:
Note the equal sign, what you do to one side, you do to the other. Isolate the variable, x. Do the opposite of PEMDAS.
First, add 7 to both sides:
9x - 7 (+7) = - 7 (+7)
9x = -7 + 7
9x = 0
Next, divide 9 from both sides:
(9x)/9 = (0)/9
x = 0/9 = 0
x = 0 is your answer.

Sometimes true: when x = y it's true ; when x ≠ y it's not true.
