<span>A) 2x - 7y = 13
B) 3x + y = 8
Multiplying equation B by 7
B) 21x + 7y = 56 then adding it to A
</span><span>A) 2x - 7y = 13
23x = 69
x = 3
y = -1

Answer:
41.2 in
Step-by-step explanation:
The short side of a "golden rectangle" is 2/(1+√5) times the length of the long side:
(66.6 in)(0.618034) ≈ 41.161 in
The shorter side is 41.2 inches long.
Answer:
The equation of the line of best fit is: y = -2.33x + 591.78
The correlation coefficient is: -0.99
There is a strong negative correlation
Step-by-step explanation:
The negative correlation is seen in the sign of the correlation coefficient, which is negative.
The correlation is strong because the absolute value of the correlation coefficient (0.99) is near to one
