A. $756.47

Step-by-step explanation:

We have been given an equation that fits the scatter plot of the values for stock ABC over the past month with an r-value of 0.9858.

To find the value of ABC after 22 days, we will substitute in our given equation as:

Therefore, the value of stock ABC will be $756.47 after 22 days and option A is the correct choice.

the answer to this question is yes

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
