Answer:

(74/9,274/9)

Step-by-step explanation:

You have

x-5y=4 and

y=2x+14

so we subsitute y in the first equation

x-5(2x+14)=4

x-10x-70=4

-9x=74

x=74/9

so y=2(74/9)+14

y=148/9+14

y=274/9

so the oredered pair is

(74/9,274/9)

Alchen [17]

Answer:

By assuming that shortest feather has a length of 1/4 inches, the length of the longest feather is 2 inches.

Step-by-step explanation:

A mathematical translation of the statement of the problem is:

$x - y = \frac{7}{4}$

Where x, y represent the lengths of the longest and shortest feathers, respectively. Let assume that length of the shortest feather is 1/4 inches. Then, the length of the longest feather is:

$x = y + \frac{7}{4}$

$x = 2$

By assuming that shortest feather has a length of 1/4 inches, the length of the longest feather is 2 inches.

Answer:

Step-by-step explanation:

The f^-1 notation indicates you need to find the inverse of the function

y=2x+1

x=2y+1

Exchange the x & y variables. Note this is what accomplishes that reflection across the line y = x

7=2y+1

-2y=1-7

-2y=-6

Divide both side of the equation by -2

negative divide negative is positive so

y=3
