It is the blue one. By doing the vertex formula we can see the x value of the vertex is -3/4. The blue one best represents that as the negative A value shows the parabola will be facing down too and have a maximum not a minimum for the vertex

Answer:

y = 0.75

Step-by-step explanation:

(4y + 1) = 4

A rectangular parking lot is 120 feet long and 75 feet wide. Diego made another scale drawing of the parking lot at a scale of 1

Answer:

We kindly invite you to read carefully the explanation detailed below for further details.

Step-by-step explanation:

At first we understand that Diego converted length and wide units from feet to inches ( $1\,ft = 12\,in$ ) and then he divided each term by 180, since he was using a reduction scale, so that rectangular parking lot can be represented on paper. That is:

Step 1 - Unit conversion:

$l = 120\,ft$ ( $l$ - Length)

$l = 120\,ft\times \frac{12\,in}{1\,ft}$

$l = 1440\,in$

$w = 75\,ft$ ( $w$ - Width)

$w = 75\,ft\times \frac{12\,in}{1\,ft}$

$w = 900\,in$

Step 2 - Applying scaling:

$l' = \frac{l}{180}$ ( $l'$ - Scaled length)

$l' = \frac{1440\,in}{180}$

$l' = 8\,in$

$w' = \frac{w}{180}$ ( $w'$ - Scaled width)

$w' = \frac{900\,in}{180}$

$w' = 5\,in$
