Krystal’s poster project for reading class is 2 feet high and 1 1 2 feet wide. Her friend Victoria’s poster is 4 feet high and 1

Bess [88]

The area of Victoria's poster is twice the area of Krystal's poster.

<h3>How compare the areas of two similar posters</h3>

The two areas are shown in the image attached below. Each poster represents a rectangle and the ratio between the two areas ( $r_{A}$ ), no unit, is defined by the following formula:

$r_{A} = \frac{w_{V}\cdot h_{V}}{w_{K}\cdot h_{K}}$ (1)

Where:

$w_{V}$ - Width of Victoria's poster, in feet.
$h_{V}$ - Height of Victoria's poster, in feet.
$w_{K}$ - Width of Krystal's poster, in feet.
$h_{K}$ - Height of Krystal's poster, in feet.

If we know that $h_{V} = 4\,ft$ , $w_{V} = 1.5\,ft$ , $h_{K} = 2\,ft$ and $w_{K} = 1.5\,ft$ , then the ratio between the two areas is:

$r_{A} = \frac{(4)\cdot (1.5)}{(2)\cdot (1.5)}$

$r_{A} = 2$

The area of Victoria's poster is twice the area of Krystal's poster. $\blacksquare$

Consider the equation y = a - bx. If y = 6 when x = 1 and y = 0 when x = 2, find . = х

Trava [24]

Answer:

see explanation

Step-by-step explanation:

(a)

y = $\frac{a}{x}$ - bx

substitute y = 6 , x = 1 into the equation

6 = a - b → (1)

substitute y = 0 , x = 2 into the equation

0 = $\frac{a}{2}$ - 2b ( multiply through by 2 to clear the fraction )

0 = a - 4b → (2)

multiply (1) by - 4

- 24 = - 4a + 4b → (3)

add (2) and (3) term by term to eliminate b

- 24 = - 3a + 0

- 24 = - 3a ( divide both sides by - 3 )

8 = a

substitute a = 8 into (1) and solve for b

6 = 8 - b ( subtract 8 from both sides )

- 2 = - b ( multiply both sides by - 1 )

2 = b

Then a = 8 and b = 2

(b)

when x = 4

y = $\frac{8}{4}$ - 2(2) = 2 - 4 = - 2
