Answer:

Step-by-step explanation:
To find the distance between two points, use the distance formula.
The distance formula is:

Let (3,-4) be x₁ and y₁ and let (5,4) be x₂ and y₂. Therefore:

Answer:
<h2>(0,1) and (2,5).</h2>
Step-by-step explanation:
The graph of the inequality is attached.
Remember, a solution of an inequality is a point on the shaded region. Also, it must satisfy the inequality expression

From the graph we know the possible answers are (0, 1) and (2, 5), let's prove it.
<h3>For (0, 1):</h3>

Which is true, so (0, 1) is solution.
<h3>For (2, 5):</h3>

Which is true, so (2, 5) is solution.
Therefore, the solutions are (0,1) and (2,5).
Ok so
since we h ave
3.5=1 day's morning
and
2.3=1 day's afternoon
we need to add them to find 1 day and multiply by 6 (number of days)
that answer is not listted so we make into anohter form
this wold be
6 times (3.5 +2.3)
if we distributed
a(b+c)=ab+ac
6(3.5+2.3)=6 times 3.5+6 times 2.3
this is D
