A student showed the steps below while solving the inequality Ix-4I <= 1by graphing.
Step 1: Write a system of equations y1 = Ix-4I<= 1
Step 2: Graph the two equations:
graph picture
Step 3: Identify the values of x for which y1 <= y2: X=3 or x=5
Step 4: Write the solution in interval notion:
(-infinity, 3)u(5, infinity)

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

THE ANSWER IS:
Step 3, because the value for x for which y1 <= y2 also include values between 3 and 5.

 Step 3, because the value for x for which y1 <= y2 also include values between 3 and 5.

898.1666667

step-by-step explanation:

5389/6 = 898.1666667

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
