Which linear equation can be derived from this proportion?

inn [45]

9514 1404 393

Answer:

D. 2x - 6 = 5x - 45

Step-by-step explanation:

To make the linear equation, we can multiply the given equation by 5(x-3).

$\dfrac{x-9}{x-3}=\dfrac{2}{5}\\\\\dfrac{(x-9)(5)(x-3)}{(x-3)}=\dfrac{2(5)(x-3)}{5}\\\\5(x-9)=2(x-3)\qquad\text{looks like }\textit{cross multiply}\\\\5x-45=2x-6\qquad\text{use the distributive property; matches D.}$

The length of a rectangular mural is 2 ft more than three times the height. The area is 165 ft^2. Find the height of the mural.

NISA [10]

Answer:

x=-1±4√31/3 ft is the height

Step-by-step explanation:

let the height be x ft.

then the length would be 3x+2

area = L*H= x(3x+2)

165=3x²+2x

0= 3x²+2x -165

dividing the whole equation by 3

0=x²+2x/3-55

(x)²+2(x)(1/3) +(1/3)² -55 -(1/9)=0

(x+1/3)²- 495-1/9=0

(x+1/3)²= 496/9

taking square root on both sides

(x+1/3)= ±4√31/3

x= ±4√31/3-1/3

x=-1±4√31/3 ft is the height
