Writing the Inverse of a Function What is the inverse of fx) = 1x + 2?
h(x) =
3
1x+2
+2

o h(x) = {x-2
O h(x) = 3x - 2
O h(x) = 3x - 6

Jack has a piece of red ribbon that is two times as long as his piece of blue ribbon. he says that he can use two different equation to find out how long his piece of red ribbon is compared to his piece of blue ribbon is. is he correct? explain his reasoning

How can you find the mean absolute deviation (mad) for this set of data?

The value of x in this system of equations is 1. 3x + y = 9 y = –4x + 10 substitute the value of y in the first equation: combine like terms: apply the subtraction property of equality: apply the division property of equality: 3x + (–4x + 10) = 9 –x + 10 = 9 –x = –1 x = 1 what is the value of y?
