Use the distance formula:

(6, -2), (-2, -12)

⇒


⇒


= 12.8
The distance between points T and U is
12.8 units.
A=6
B= -1/2
C= 11
I had this one on my test and I got it right have a good day
BOTH they both are correct bc they both state the same thing perimeter is both length+ both width's so l+l+w+w=2l+2w
Answer:
a. Yes
b. No
Step-by-step explanation:
To find if an ordered pair is a solution to the inequality, substitute its x and y values for the x and y in the inequality and solve. If the equation is true, then it is a solution. If it is not, then it is not a solution.
1) First, substitute the x and y values of (3, 1) into the inequality. So, substitute 3 for x and 1 for y:

1 is greater than or equal to 1, so (3,1) is a solution.
2) Second, do the same with the point (1, -4). Substitute 1 for x and -4 for y:

However, -4 is not greater than or equal to -3, thus (1, -4) is not a solution.
