Answer:
15
Step-by-step explanation:
you do parenthesis first
9-6=3 then add 3 to 12
3+12=15
Since the scatter plot has a line of best fit (the line you created), the points follow a linear pattern. Then looking at the slope, we see that it is positive (moves upward). The correlation is positive.

Answer:
x = -2 and 1
Step-by-step explanation:
Given :
f(x) = x+2
g(x) = -x²+4
The solution to the equation f(x) = g(x)
=> x+2 = -x²+4
=> x²+x = 4-2
=> x²+x -2 = 0
By factorisation
=> x²+2x-x -2 = 0
=> x(x+2) -1(x+2)
=> (x+2) (x-1)
x = -2 and 1
