The function is given by

$\\ \tt\hookrightarrow D(p)=1500-25p$

Price must be greater than 0

$\\ \tt\hookrightarrow 1500-25p\geqslant 0$

$\\ \tt\hookrightarrow 1500\geqslant 25p$

$\\ \tt\hookrightarrow p\leqslant 60$

Now

$\\ \tt\hookrightarrow D_f\in (-\infty,60]$

Fawzi's SUV is 6 feet 4 inches

Nat2105 [25]

Answer:

<u>9 feet 2 inches</u>

Step-by-step explanation:

Given :

⇒ Height of SUV = <u>6 feet 4 inches</u>

⇒ Height of box = <u>2 feet 10 inches</u>

<u />

============================================================

Solving :

⇒ Total Height = Height of SUV + Height of box

⇒ Total Height = 6 feet 4 inches + 2 feet 10 inches

⇒ Total Height = 8 feet 14 inches

* But, 12 inches = 1 feet *

Hence,

⇒ Total Height = 8 feet + 1 foot + 2 inches

⇒ Total Height = <u>9 feet 2 inches</u>

Use FOIL and the distributive property to derive (a-b)^3

Sergio039 [100]

Answer:

(a-b)^3 = $\left(a-b\right)^3=a^3-3a^2b+3ab^2-b^3$

Step-by-step explanation:

(a-b)^3 = (a-b)(a-b)(a-b)

According to the perfect cube formula (a-b)^3 = $\left(a-b\right)^3=a^3-3a^2b+3ab^2-b^3$

And there you have it! The perfect cube formula already solved your equation!

How do the constant of proportionality and slope relate to the unit rate

Pepsi [2]

Answer:

When a relationship is proportional, all y over x ratios simplify to the slope of the line which is the constant of proportionality or the unit rate, with one as a denominator. Example: Consider the equation y = 60x. The slope is 60. The rate of change is 60 units for every one unit.

\begin{aligned} &y=2x +1 \\\\ &x-y=-3 \end{aligned} y=2x+1 x−y=−3 Is (2,5)(2,5)left parenthesis, 2, comma, 5, right

trapecia [35]

Answer:

Yes

Step-by-step explanation:

Given the system of equations

$\begin{aligned} &y=2x +1 \\\\ &x-y=-3 \end{aligned}$

We want to determine if (2,5) is a solution of the system.

We can do this by substitution of the given point into the equations and see if it holds.

Given (x,y)=(2,5), x=2, y=5

<u>In the first equation</u>

y=2x+1

5=2(2)+1

5=5

Therefore, <u>the point (2,5) satisfies the first equation.</u>

<u>In the second equation</u>

$x-y=2-5=-3$

Since our result (-3) is equal to the Right Hand Side, <u>the point also satisfies the second equation.</u>

<u />

Therefore, (2,5) is a solution of the system.
