Identify the function shown in this graph. .
A. y=x+4
B. y = -x+ 4
C. y = -x-4
D. y= x - 4

Consider the table below. x y -1 -5 0 5 1 11 2 13 3 11 complete the standard form equation representing the quadratic relationship displayed above, where a, b, and c are constants.

Twice the sum of a number and 4 is equal to three times the difference of the number and 7. find the number.

The linear combination method is applied to a system of equations as shown. 4(.25x + .5y = 3.75) → x + 2y = 15 (4x – 8y = 12) → x – 2y = 3 2x = 18 what is the solution of the system of equations? (1,2) (3,9) (5,5) (9,3)
