Graph the image of this triangle after a dilation with a scale factor of 2 centered at the origin.

Svet_ta [14]

Answer:

Since, the coordinates of the given triangle are (0,0), (4,-4) and (-4,-2)

In the dilation by the scale factor k with centered at origin,

$(x,y)\rightarrow (kx,ky)$

Thus, If the dilation occurs by the scale factor of 2 with centered at origin,

New coordinates of the triangles are,

$(0,0)\rightarrow (2\times 0, 2\times 0)$

$(-4,4)\rightarrow (2\times -4, 2\times 4)$

$(-4,-2)\rightarrow (2\times -4, 2\times -2)$

Thus, the coordinates of new triangle are,

(0,0) ( -8, 8) and (-8,-4)

FOIL when multiplying two binomials.

First:
√ 3*√ 3= 3

Outer:
√ 3 *2 = 2√3

Inner:
-4*√3= -4√3

Last:
-4*2=-8

Put it together
3+2√3-4√3-8

Simplify
(-2√3)-5

Final answer: (-2√3)-5

Javier designs leather shoes at his workshop. He charges $45 for women's shoes and $50 for men's shoes. He needs to make $2,500

Ipatiy [6.2K]

We write the equation that is given above,<span>
45x + 50y = 25000
Since there are no women, x should be zero. We are then left with the equation,
50y = 25000
<span>To answer, we divide both sides of the equation by 50 giving us 50. Thus, Javier needs 50 male customers for him to meet his expenses. </span></span>
