Answer:
21
Step-by-step explanation:
x2 + 3.4y, when x = 2, y = 5
(2)2+3.4(5)
2×2+3.4×5
4+5×3.4
4+17

Answer:
0, -2
Step-by-step explanation:
The solution of an ordered pair is when the two lines intersect on one of the boxes.
In this case, the two lines meet at <u>0,-2</u>
<u />
The x is 0
The y is -2
Supplementary understanding of why it is negative:
Since the x (horizontal line) hasn't moved anywhere from the middle, the origin or (middle line) represents zero, therefore since it HAS NOT moved, it shall remain zero.
Since the y (vertical line) meets at "two-down", down would indicate it is negative (below the origin), and it only went down two boxes, so that's where the two came from.

So plot the 5 on the y axis then go down 1 and across the the right 3
S+9
More than suggests addition.
