It is more convinient to use substitution
Answer:
1
Step-by-step explanation:
1st way: We can find the slope of the line by plugging the two points into the slope formula. If you do, slope would be (-3/2-3/2)/(-3/2-3/2) which simplifies to -3/-3 which is 1. The slope is 1.
2nd way: You can just use logic to figure it out because since the x and y in both of the points are equal to each other, we know that the slope has to be 1.

Correct expression is 
. As n is greater then or equal to so circle will be closed . Correct options are B) and D)The circle is closed.
<u>Step-by-step explanation:</u>
Here we have , Solve Negative two-thirds n less-than-or-equal-to 16. We need to find Which of the following must be true about the inequality and the resulting graph . Let's find out:
We have expression as : 
⇒
⇒ 
⇒ 
⇒ 
⇒ 
⇒
Therefore , Correct expression is . As n is greater then or equal to so circle will be closed . Correct options are B) and D)The circle is closed.
Answer:
First some theory we need to solve this problem.
For a circle of radius R, the perimeter is:
P = 2*pi*R
where pi = 3.14
If we have a section of this circle, defined by an angle θ, the length of this arc will be:
A = (θ/360°)*2*pi*R
In the case of the problem, the total distance that the child travels is equal to the length of an arc of 310° in a circle of radius r = 6ft.
Using the above formula, we know that the length of this arc is:
A = (310°/360°)*2*3.14*(6ft) = 32.4 ft
