Well first solve for x
2x + 3 = -19
2x = -22
x = -11
Therefore yes, -11 is a solution for the function.
Answer:

Step-by-step explanation:
The coordinates of A = (2,9)
The coordinates of B = (7,4)
Let M (x,y) be the mid point of A and B.

So, the coordinates of mid point of A and B is
.
Answer:
C. 72
Step-by-step explanation:
-3 x -2 = 6
6 x 3 = 18
18 x 4 = 72
Answer:
24
Step-by-step explanation:
The multiples of 8 are 8,16,24,32 etc. and the multiples of 6 are 6,12,18,24,30, ect. The answer is 24 because it is the lowest multiple of 6 that crosses with multiples of 8.
X + 2y = -6
2y = -x - 6
y = (-x - 6)/2
answer is D. Last one
y = (-x - 6) / 2
