lesya [120]

Answer:

k=0.106383

Step-by-step explanation:

Let's solve your equation step-by-step.

12=4.7k+11.5

Step 1: Flip the equation.

4.7k+11.5=12

4.7k=0.5

Step 3: Divide both sides by 4.7.

4.7k

4.7

=

0.5

4.7

k=0.106383

PLEASE HELP ME GET THIS DONE
Grace [21]

Answer:

C

Step-by-step explanation:

The line on the left has equation y = x - 2

The start of the line has an open circle at x = 3 meaning that x ≠ 3

The line is defined as y = x - 2 for x < 3

The line on the right has equation y = x - 1

The start of the line has a closed circle at x = 3 meaning that x can equal 3

The line is defined as y = x - 1 for x ≥ 3

Thus the definition of the function is C
