1/5m + 6 = 3/4<br> What is m?
kakasveta [241]
1/5m + 6 = 3/4

subtract 6 from each side

1/5m = 3/4 - 6

divide 1/5 from each side

m = 3/4÷1/5 - 6/5

simplify

m= 3/4 × 5 - 6/5
m = 15/4 - 6/5
m = 75/20 - 24/20
m = 51/20

m = 2 11/20

2x^2 + 2y^2 - 8x + 10y + 2 =0
scoray [572]

A circle of radius <em>r</em> centered at (<em>a</em>, <em>b</em>) has equation

(<em>x</em> - <em>a</em>)² + (<em>y</em> - <em>b</em>)² = <em>r </em>²

To get the given equation in this form, complete the square with respect to both <em>x</em> and <em>y</em>.

2<em>x</em>² - 8<em>x</em> = 2 (<em>x</em>² - 4<em>x</em>)

2<em>x</em>² - 8<em>x</em> = 2 (<em>x</em>² - 4<em>x</em> + 4 - 4)

2<em>x</em>² - 8<em>x</em> = 2 ((<em>x</em> - 2)² - 4)

2<em>x</em>² - 8<em>x</em> = 2 (<em>x</em> - 2)² - 8

2<em>y</em>² + 10<em>y</em> = 2 (<em>y</em>² + 5<em>y</em>)

2<em>y</em>² + 10<em>y</em> = 2 (<em>y</em>² + 5<em>y</em> + 25/4 - 25/4)

2<em>y</em>² + 10<em>y</em> = 2 ((<em>y</em> + 5/2)² - 25/4)

2<em>y</em>² + 10<em>y</em> = <u>2 (</u><u><em>y</em></u><u> + 5/2)² - 25/2</u>

So we have

2<em>x</em>² + <u>2</u><u><em>y</em></u><u>²</u> - 8<em>x</em> + <u>10</u><u><em>y</em></u> + 2 = 0

2 (<em>x</em> - 2)² - 8 + <u>2 (</u><u><em>y</em></u><u> + 5/2)² - 25/2</u> + 2 = 0

2 (<em>x</em> - 2)² + 2 (<em>y</em> + 5/2)² = 37/2

(<em>x</em> - 2)² + (<em>y</em> + 5/2)² = 37/4

(<em>x</em> - 2)² + (<em>y</em> + 5/2)² = ((√37)/2)²

which means this circle has radius (√37)/2 and center (2, -5/2).
