Answer:

20x - 16

Step-by-step explanation:

We can first do 1/2 (36x - 14), getting 18x - 7.

Then our expression becomes 18x - 7 + 2x - 9.

We can combine like terms, getting 20x - 16.

Write the equation in standard form for the circle with center (0, 9) passing through (0, 27/2)

sammy [17]

Given

coordinates of center= (0,9)

Circle passes through (0, 27/2)

Find

Equation of circle

Explanation

The equation of circle in standard form is

$\begin{gathered} (x-h)^2+(y-k)^2=r^2 \\ (x-0)^2+(y-9)^2=r^2 \end{gathered}$

We know the circle passes through (0,27/2), then

$\begin{gathered} (0-0)^2+(\frac{27}{2}-9)^2=r^2 \\ r=4.5 \end{gathered}$

So the equation in the standard form is

$(x-0)^2+(y-9)^2=4.5^2$

Final Answer

$(x-0)^2+(y-9)^2=4.5^2$
