To find the length of a line given two points, we are going to use the distance formula, which is defined below:

(
and
are the two points)
The points in this problem are (2, 5) and (-1, 5). We can find the distance of DC by substituting these values into the distance formula and simplifying, as shown below:

- Substitute values into formula

- Combine like terms and then simplify
to 0

- Compute


- Compute

The length of DC is 3.
Answer:
P (green/yellow) = 65/139
Step-by-step explanation:
42 + 45 + 20 + 32 = 139 possibilities
45 + 20 = 65 desired outcomes
65/139

The statements that describe the given inequality are as follows:
- Riley wants to save at least $350. She earns $10 each week walking dogs. She has $75 saved. How many weeks will Riley need to walk dogs?
- Elijah would like to have at least $350 to take on vacation for spending money. He already saved $75 and plans to save $10 per week from his weekly paycheck. When will Elijah have enough money to go on vacation?
<h3>What is the inequality and it's meaning?</h3>
The inequality is given by:

It means that the sum of a fixed amount of 75 plus a variable amount of 10 has to be of at least 350.
Hence, the 2nd and the 3rd options are correct.

Answer:
Step-by-step explanation:
eq. of line x-3y-6=0
3y=x-6
y=1/3 x-6/3
or
y=1/3 x-2
its slope m1=1/3
y=2x+5
slope m2=2
if α is the angle between the lines then

X+(3x+4)=72
4x+4=72
4x=68
X=17
