Answer:

Step-by-step explanation:

First, simplify the equation.

-3x+1<7

-3x<6

x>-2 (the sign flips because you are dividing by negative)

> means x is greater than -2 so the line will go towards the right.

Because the sign is >, the dot is open.

Should it be facing left or right ?

riadik2000 [5.3K]

Answer:

Facing Right

Step-by-step explanation:

Given inequalities are:

4-x≤-1

Subtracting 4 from both sides

4-x-4≤-1-4

-x≤-5

Multiplying both sides with -1. Multiplying with a negative number changes the sign of the inequality

So,

x≥5

Second Inequality:

2+3x≥17

Subtracting 2 from both sides

2+3x-2≥17-2

3x≥15

Dividing both sides by 3

x≥5

Union of both solutions:

x≥5 ∩ x≥5

=> x≥5

Hence the solution will be facing right on the number line towards all numbers greater than or equals to 5 ..

$\text{The hundredths place is the 2nd place after the decimal}\\\\\text{The number in the hundredths place in this case is 9}\\\\\text{You would round up if the number to the right of it it's 5 or greater}\\\\\text{You would keep it the same if the number to the right of it is 4 or less}\\\\\text{The number to the right of 9 is 5, so round up}\\\\\text{When you round, it would turn into: 12.90, since the 9 turns into a "10",}\\\text{then you carry the one over to the next number}\\\\$
