Answer:
y = 2x - 9.
Step-by-step explanation:
2y - 4x = -18

2y = 4x - 18
Divide both sides by 2:
y = 2x - 9.
Answer: 8
Step-by-step explanation: In this problem,
we're asked to find f(-4) or the value of the function when x = -4.
To find the value of the function when x = -4,we simply plug in a -4 for
the x in our function and we have (-4)² + (-4) - 4 or 16 + -4 - 4 which is 8.
So f(-4) = 8.

I got the answer to be 0.9. To get the mean, you add up all the data and then divide it by the number of numbers in you data, so I did 0.5+0.7+1.0+1.7+0.6+1.0=0.8 and then divided by 7, giving me 0.9.
