Find the equation of the circle with center (4,5) which passes through the y-intercept of the line 5x-2y+6=0

Elena-2011 [213]

Answer:

(x-4)^2 + (y-5)^2 = 20

Step-by-step explanation:

Rearrange the line equation of 5x - 2y + 6 = 0

So y = 5/2x +3

The y-intercept of the line equation is 3 as when x=0, y=3.

We know the Circle has the formula $(x-4)^2 + (y-5)^2 = ?^2$ from the question but with the intercept, we can find the entire equation as the y-intercept is (0,3) so we can substitute it into the equation to find the full equations so:

$(0-4)^2 + (3-5)^2 = ?^2$

This simplifies to:

$(-4)^2 +(-2)^2$ = $?^2$

16 + 4 = 20 = $?^2$

The answer is 20 so the equation of the circle is $(x-4)^2 + (y-5)^2 = 20$

Solve the equation.<br> -9x + 1 = -x + 17

ddd [48]

Answer:

The value of $x$ :

$x = -2$

Step-by-step explanation:

Find the value of $x$ :

$-9x + 1 = -x + 17$

-Add both sides by $x$ :

$-9x + 1 + x = -x + x + 17$

$-8x + 1 = 17$

-Subtract both sides by $1$ :

$-8x + 1 - 1 = 17 - 1$

$-8x = 16$

Divide both sides by $-8$ :

$\frac{-8x}{-8} = \frac{16}{-8}$

$x = -2$

So, the final answer would be $x = -2$ .
