Consider the circle represented by this equation.

LenKa [72]

Answer:

See below

Step-by-step explanation:

arrange to standard form (x-h)^2 + (y-k)^2 = r^2 h,k = center r = radius

x^2 - 4x + y^2 + 2y = 4 complete the square for 'x' and 'y'

(x-2)^2 - 4 + (y-1)^2 -1 = 4

(x-2)^2 + ( y-1)^2 = 4 + 4 + 1 = 9 '9' is equal to r^2 so r = 3

<u>center = 2,1 radius = 3 </u>

Answer:

Step-by-step explanation:

$2x^2+12x=0\qquad\text{divide both sides by 2}\\\\x^2+6x=0\\\\x(x+6)=0\iff x=0\ \vee\ x+6=0\qquad\text{subtract 6 from both sides}\\\\x=0\ \vee\ x=-6$

For a sale, a store decreases its prices on all items by 25%. An item that costs $120 before the sale now costs $120 - 0,25($120

Alexxandr [17]

Answer:

$Cost = \$120 * 1 - \$120 * 0.25$

Step-by-step explanation:

Given

$Cost = \$120 - 0.25(\$120)$

Required

Solve using distributive property

$Cost = \$120 - 0.25(\$120)$

$\$120$ can be rewritten as $1(\$120)$

So:

$Cost = 1(\$120) - 0.25(\$120)$

Factorize:

$Cost = \$120(1 - 0.25)$

Now, we can apply distributive property on the expression;

$Cost = \$120 * 1 - \$120 * 0.25$

Hence, the above is an equivalent expression.

Solving further, we have

$Cost = \$120 - \$30$

$Cost = \$90$
