What is the center of the circle with the equation: X2 + y2 +18x + 14y + 105 = 0

professor190 [17]

Answer:

(9, -7)

Step-by-step explanation:

$x^2+y^2+18x+14y+105=0\\$

Rearrange like x and y terms next to each other, then complete the square on both.

$(x-9)^2-361 + (y+7)^2 - 49 + 105 = 0$

The negative of the # numbers instead the brackets give you the centre of the circle.

What is the equation of the line that is parallel to 3x-5y=7 and passes through the point (-10,8)

Goryan [66]

Answer:

$5y - 3x = 70$

Step-by-step explanation:

The given line has equation:

3x-5y=7

We need to determine the slope of this line, so we rewrite in slope intercept form.

$y = \frac{3}{5}x - \frac{7}{5}$

The slope of this line , when we compare to y=mx+c is

$m = \frac{3}{5}$

All parallel lines have the same slope.

Hence our line also has the same slope

This line passes through (-10,8).

The equation is given by:

$y-y_1=m(x-x_1)$

We substitute the slope and point to get:

$y - 8 = \frac{3}{5}(x - - 10)$

We expand to get:

$y - 8 = \frac{3}{5}x + 6$

$y = \frac{3}{5}x + 14$

$5y - 3x = 70$

-x+3y=10 <br><br> find x and y intercept

zloy xaker [14]

$-x+3y=10 \\ \\
\hbox{x-intercept: } y=0: \\
-x+3 \times 0=10 \\
-x=10 \\
\boxed{x=-10} \\ \\
\hbox{y-intercept: } x=0: \\
-0+3y=10 \\
3y=10 \\
y=\frac{10}{3} \\
\boxed{y=3 \frac{1}{3}}$
