Anyone have any idea? i dont have any idea

ladessa [460]

Answer:

$\tt f(x)=2x^2+20x-10$

let y=f(x)

$\tt y=2x^2+20x-10$

$\tt 2x^2+10x=y+10$

$\tt x^2+10x=\frac{1}{2} y+5$

$\tt x^2+10x+25=\frac{1}{2} y+30$

$\tt (x+5)^2=\frac{1}{2} (y+60)$

$\tt 2(x+5)^2=f(x)+60$

$\boxed{\tt f(x)=2(x+5)^2-60}$

Hope it helps! :)

Using a scale, or rate, of Inch per foot, calculate the room's dimensions for your drawing.

likoan [24]

Answer:

Scaling is used to resize the dimension of a structure to fit the different platforms, like from structure to paper.

Step-by-step explanation:

To resize down-scale the dimension of a room, if the scale is 1/4 inches per foot, then the size of a 6x4 feet (width and length) room would be;

1/4 x 6 = 1.5 inches

1/4 x 4 = 1 inches

that is, 1.5 x 1 inch on paper when scaled down.
