Each X and Y in the equations don't have a number in front of them so they are all considered 1.
D = 1*(-1) - 1*(-1) = -1 -1 = -2
The answer is -2
Answer:
<h2>M = ( 5 , 2)</h2>
Step-by-step explanation:
The midpoint M of two endpoints of a line segment can be found by using the formula

where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
A(12,9), B(-2,-5)
The midpoint M is

We have the final answer as
<h3>M = ( 5 , 2)</h3>

Answer:
1560 cubic inches
Step-by-step explanation:
18x20= 360
360x13= 4680
4680/3=1560
Formula for triangle perimeter is: a + b + c. In this scenario we have:
a = 3 feet 8 inches
b = 2 feet 10 inches
c = 4 feet
a + b + c =
= 3 ft + 8 in + 2 ft + 10 in + 4 ft =
= 9 ft + 18 in
We know that 1 foot is 12 inches, so we can simplify the result to this form:
10 ft + 6 in
or:
<u>10.5 feet</u>
Answer:
There will be
billion messages sent or received in November.
Step-by-step explanation:
Given.
Number of text messages sent or received
billion.
Increment on the very next month 
Lets find what is 
⇒
⇒
So we will add this value to our previous months data.
Now
Number of text messages sent in the month of November
billion.
Rounding to the nearest tenth the answer will be
billion.
So
billion text messages were sent or received in November.
