If x and y vary directly and x=25 when y=100 find x when y=24.<br> PLEASE HELP FASTTTTTTT

Veseljchak [2.6K]

Answer:

x = 6

Step-by-step explanation:

Given that x and y vary directly then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition x = 25 when y = 100 , then

100 = 25k ( divide both sides by 25 )

4 = k

y = 4x ← equation of variation

When y = 24 , then

24 = 4x ( divide both sides by 4 )

6 = x

16. The area of the rectangle is 5x2 + 17x + 6. Find the length & width (the factors), then determine the perimeter of the r

Bezzdna [24]

Area of a rectangle is represented by the expression:

$\text{Area}=\text{length }\cdot\text{ width}$

Since, the area is defined by the following expression:

$\begin{gathered} \text{Area}=5x^2+17x+6 \\ We\text{ can factor the expression:} \\ \text{Area}=(5x+2)(x+3) \end{gathered}$

So, notice that:

$\begin{gathered} \text{Length}=5x+2 \\ \text{Width}=x+3 \end{gathered}$

The perimeter is given by the following formula:

$\begin{gathered} \text{Perimeter}=2L+2W \\ \text{Perimeter}=2(5x+2)+2(x+3) \\ \text{Perimeter}=10x+4+2x+6 \\ \text{Perimeter}=12x+10 \end{gathered}$
