1st on the left matches with y. 2nd matches with 6x-2y. 3rd matches with 2x+y.
4,734 is the answer because I used my calculator XD

Answer:
A. (1 2/3, 4 2/3)
Step-by-step explanation:
If you graph the equations, you see the lines intersect at the solution point:
(x, y) = (1 2/3, 4 2/3)
I used scatter plot graph in the insert graph function of excel and added a trend line that shows the equation of the line of best fit and the r.
The line that can be applied in this function is linear with an equation of y = 3800.6x - 5223.6 and the regression is r² = 0.8925. The y intercept represents when the starting point of a line starts. It is a strong correlation since the value of r² that is equal to 0.8925 is close to 1. We can solve the value of the investment after 6 years using the equation above.
y = 3800.6x - 5223.6
y = 3800.6(6) - 5223.6
y = 17,580
Answer:
-19
Step-by-step explanation:
x= -5 y = -2
-x^2 - 4xy + y^2
- -5^2 -4(-5 x -2) -2^2 Plug in
+ 5^2 -4(-5 x -2) -2^2 Change the signs for - -5
5^2 - 2^2 - 4(10) Place Liked Terms together
25 - 4 - 40 Subtract
21 - 40
-19
