Answer:
(x) = 
Step-by-step explanation:
let y = f(x) and rearrange making x the subject, that is
y = 5x + 4 ( subtract 4 from both sides )
y - 4 = 5x ( divide both sides by 5 )
= x
change x to (x) and y back to x, thus
(x) =
Answer:
y = 4x - 1
Step-by-step explanation:
Just plug it into slope intercept form which is y = mx + b

64, 68, 71, 87, 215, 215
To find the median, we must find put the data set in order from least to greatest.
Great! We already have it like that :)
Now, our median is in between 71 and 87
So, basically, we have to find what the median of 71 and 87 are.
Simply add the two numbers together, and then divide it by 2.
71 + 87 = 158
158 ÷ 2 = 79
So, 79 is your median!
