Answer:

The lines are parallel.

There is no solution to the system.

Step-by-step explanation:

4x − 9y = 54,

16x − 36y = 208

 

−16x + 36y = −216

16x − 36y = 208

-------------------------------------------

 0 + 0 = −8

   0 = −8

Since this is not true, there are no solutions

The lines are parallel

If f(x) = 5x-3, which expression represents its inverse function?
valentinak56 [21]

Answer:

Pretty sure it's C

Step-by-step explanation:

For inverse functions, I do the opposite operation

the only logical inverse function I see working in this expression would be C

divide the 5 from 5x and add the 3

Also, subtract the f(x) on both sides to get the "- y"

so, you get : 5/x + 3 = - y (f(x) is just "y")

Aneli [31]

Answer:

y = 5/8x - 3

Step-by-step explanation:

(8,2) and (-8,-8)

m=(y2-y1)/(x2-x1)

m = ( -8 -2)/ (-8 - 8)

m = (-10)/(-16)

m = 5/8

y - y1 = m(x - x1)

y - 2 = 5/8(x - 8)

y - 2 = 5/8x - 5

y = 5/8x - 3
