It gained 4 lbs:) 6*4 = 24
24+12 = 36
The answer is C: x < -2
The fact that it is less than -2 is shown by the open circle on -2, and the arrow pointing to the left. An open circle means that the number cannot be included (which is why it can't be "less than or equal to," but instead is just "less than."), and the line pointing to the left means that your variable is specifically less than the number circled.
MxM=M^2 (m squared)
Highest variable comes first, so it'd be m^2+5m+6
(m+2)(m+3) is your answer. That is it factored. If that equation equals 0, then m=-2 or -3
Answer:
<h3>No, they are not equivalent</h3>
Step-by-step explanation:
Are the following systems equivalent? How do you know?
For the equation;
2x+y= -4 ... 1
7x+7y=0 ... 2
Let us find the solution of the equation;
From 1;
y = 4 - 2x
Susbtitutw into 2;
7x + 7(4-2x) = 0
7x + 28 - 14x = 0
-7x + 28 = 0
7x = 28
x = 28/7
x = 4
Recall that y = 4-2x
y = 4 - 2(4)
y = 4 - 8
y = -4
The solution is (4, -4)
For the other equations;
5x+6y= 4 ... 1 * 1
4x+2y= -4 ..... 2 * 3
___________________
5x+6y= 4
12x+6y= -12
Subtract
5x-12x = 4 + 12
-7x = 16
x = -16/7
Since the solutions to both simultaneous equations are different, hence the systems of equations are not equivalent.
Answer:
0.714 free throws.
Step-by-step explanation:
Anna made 20 out of 28 free throws.
Free-throw average = 
= 0.7142857143 free throws.
This equals 0.714 free throws (answer rounded up to the nearest thousandths)
