Suzie made a mistake in the following problem. the mistake was made in line only input the number of the first incorrect line. line 1 7(6) ÷ 5 + 42 line 2 7(6) ÷ 5 + 16 line 3 42 ÷ 5 + 16 line 4 42 ÷ 21 line 5 2

Mistake in Line 2

Step-by-step explanation:

Line 1  

7(6) ÷ 5 + 42  

Line 2  

7(6) ÷ 5 + 16  

Line 3  

42 ÷ 5 + 16  

Line 4  

42 ÷ 21  

Line 5  

2

To simplify any expression we use order of operation

Line 1 is 7(6) ÷ 5 + 42  

Order of operation is PEMDAS

First we start with parenthesis

so we multiply 7(6) in line 2

7*6- 42

So Line 2 is 42 ÷ 5 + 42  

Hence there is a mistake in Line 2

choice b is correct

step-by-step explanation:

we have been given the following system of linear inequalities;

we are required to graphically determine the solution to these system of inequalities. using a graphing tool, the solution is as shown in the attachment below;

step by step explanation: when u removing the parentheses and combined them that would be : x+3y-x-y=2y
