2|x+5.3| = 4.2 is equivalent to

(1) 2(x+5.3) = 4.2 when x+5.3 >= 0
solve x = -3.2 when x >= -5.3 ... good value
('good value' means the value has no conflict with the condition -- when)

and

(2) 2[-(x+5.3)] = 4.2 when x+5.3 < 0
solve x = -7.4 when x < -5.3 ... also good

x = -3.2 or -7.4

Given that latitude and longitude describe locations on the Earth with respect to the equator and prime meridian.

Latitude High Temp

("N)  

 

12 53

 

16 41

 

30 67

 

36 63

 

32 70

 

11 58

 

10 61

 

33 67

 

30 72

 

 

Slope 0.732

Int -21.56266667

Regression line is y = 0.732x-21.563 where x represents the latitude and y high temperature

Since slope = 0.732, we get temp increases by 0.8 degree for 1 degree increasenorth in latitude

Hence option c is right
