A student showed the steps below while solving the inequality |x - 4| <= 1 by graphing.

Step 1: Write a system of equations: y1 = |x - 4|; y2 = 1

Step 2: Graph the 2 equations

Step 3: Identify the values of x for which y1 <= y2: x = 3 or x = 5.

Step 4: Write the solution in interval notation:

What is the first step in which the student made an error?

Anybody on Edg will know this question.

c.35

step-by-step explanation:

8+13=21

21+8=29

29+6=35

d

step-by-step explanation:

given

y + 3 = - 4(x - 2) ← distribute the parenthesis

y + 3 = - 4x + 8 ( subtract 3 from both sides )

y = - 4x + 5 → d

take it another

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
