Replace,

x = y

Or

x = f(x)

then us stay:

x = 5y + 12

Isolate 5y


5y = x - 12

Dividing both the sides by 5

y = x/5 - 12/5

Then, replace y = f^-(x)

f^-(x) = x/5 - 12/5

Hope this helps

Which set of ordered pairs below is a function?
Paha777 [63]
The answer is A.

Ordered pairs that equate to a function would not have two separate points with the same x-value. In other words, every x-value must be associated with only one y-value.

URGENT WORTH 20 POINTS
Triss [41]
If we were to draw a best fit line, the y-interest would be near 15, and the slope would be negative.

In the options given, the slope is either -3 or -13. If we imagine a line through the plotted points, the rise would be about 15 while the run would be about 5. This means the slope is about -3.

The best answer is y = -3x + 15

PLEASE HELP!! 10 POINTS
kenny6666 [7]

Check the picture below.

we know B is the midpoint of AC, and we know ED is 4 units, since AD is a total of 8, then AE must also be 4 units, meaning point E is the midpoint of AD.

since E is the midpoint of AD and B is the midpoint of AC, then EB is the midsegment of the triangle, and is parallel to the base DC.

∡ABE = 60°

∡AEB = 90°
