(b) Negative correlation.
(c) £3500
Answer:
The answer to your question is: D = non of the above
Step-by-step explanation:
Data
-4x - 4y = -5 (I)
x - 2y = 1 (II)
Process
Find the slopes of both lines
(I) -4x - 4y = -5
-4y = 4x + 5
y = 4/-4 x + 5/-4
y = - x + 5/4
(II) x - 2y = 1
- 2y = - x + 1
y = -1/-2 x + 1/-2
y = 1/2 x - 1/2
The slopes are different slope 1 = -1 and slope 2 = 1/2, so there is no relation between the lines.
The correct answer is letter C
<span>2 4/9 = 22/9
Area of square = a^2 = (22/9)^2 = 484/81 square inches.
