The strategy for winning every time appears to be to ensure that the remaining number of coins is a multiple of 6. Then the first player can ensure a win by taking 2 coins to make the total number be 48.

An artist designed a badge for a school club. Figure ABCD on the coordinate grid below shows the shape of the badge.
dedylja [7]

Answer:

(8, 4)

Step-by-step explanation:

<em>AD is enlarged to JM</em>

<em>AD² = 2² + 1² = 4 + 1 =5</em>

<em>AD =  √5</em>

then you plug in JM

<em>JM² = 6² + 3² = 36 + 9 = 45</em>

<em>JM = √45 = 3 √5</em>

<em>so if </em>

<em>JM=3 AD</em>

then

<em>ML= 3 DC </em>

<em>then you add</em>

<em>5+3=8</em>

the coordinates for point L are (8, 4)

Could someone help me for this?
lina2011 [118]

Answer:

x = - \frac{5}{3} , x = \frac{5}{2}

Step-by-step explanation:

to find the points of intersection equate the 2 equations , that is

7x - 15 = 10 + 12x - 6x² ( subtract 10 + 12x - 6x² from both sides )

6x² - 5x - 25 = 0 ← factor the quadratic on left side

consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term

product = 6 × - 25 = - 150 and sum = - 5

the factors are - 15 and + 10

use these factors to split the x- term

6x² - 15x + 10x - 25 = 0 ( factor the first/second and third/fourth terms )

3x(2x - 5) + 5(2x - 5) = 0 ← factor out (2x - 5) from each term

(2x - 5)(3x + 5) = 0

equate each factor to zero and solve for x

3x + 5 = 0 ⇒ 3x = - 5 ⇒ x = - \frac{5}{3}

2x - 5 = 0 ⇒ 2x = 5 ⇒ x = \frac{5}{2}
