Find an ordered pair (x, y) that is a solution to the equation.<br><br> x-5y=5
timurjin [86]

Answer:

(x,y)=(0,-1)

Step-by-step explanation:

Observe that the equation x-5y=5 can be transformed in the equation of a line

x-5y=5\\-5y=5-x\\y=\frac{x-5}{5}\\y=\frac{1}{5}x-1

Since x can take any value then the equation has infinite solutions. But we need only an solution (x,y). Then, taking x=0 we have that y=\frac{1}{5}*0-1=-1.

Therefore the ordered pair (x,y)=(0,-1) is a solution of the equation.

The area if a rectangle is 53.6cm^2.If the length is multiplied by four and the width is halved, the area would then be?
e-lub [12.9K]

Answer:

26.8cm²

Step-by-step explanation:

the area if a rectangle is 53.6cm^2.If the length is multiplied by four and the width is halved, the area would then be?​

Area of rectangle = length x width

53.6 = 4L x 1/2 W

53.6 = 2L × W

Divide both sides by 2

L × W = 53.6 ÷ 2

New area  = 26.8cm²

Given the parent functions f(x) = log3 (5x − 5) and g(x) = log3 (x − 1), what is f(x) − g(x)?. . a. f(x) − g(x) = log3 (4x − 4).
grandymaker [24]
f ( x ) = log _{3} ( 5 x - 5 ), g ( x ) =log _{3} ( x - 1 ); \\ f ( x ) - g ( x ) = log _{3}( 5 x - 5 ) - log _{3}( x - 1 ) = \\ log _{3}   \frac{5(x-1)}{x-1}  = log _{3} 5
Answer: C ) f ( x ) - g ( x ) = log3 5
