Kimmie solves the follow expression, looking at her steps, explain her mistake. 3x (3+ 12 = 3)-4
3x (15 = 3)-4
3x5-4
15-4
11

-6.67

Step-by-step explanation:

3x(3+12=3)-4

3x(15=3)-4

3x(15/-3)-4

3x(-5)-4

3x(20)

x=20/-3

x= -6.67

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3

step-by-step explanation:

y=sec x is the correct answer
