A biologist measured the length and mass of 20 reptiles. The equation y=0.3x – 2 is the line of best fit for the data, where x is the length, in centimeters, and y is the mass, in grams.
Based on the equation, what is the approximate length of a reptile that has a mass of 20.5 grams?
O A 62 cm
B. 66 cm
C. 70 cm
D. 75 cm

question:

could we have options?

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
