Step-by-step explanation:
<em>Correct me if I'm wrong but...</em>
<em>1st you would choose two ordered pairs. Like, for instance, in the graph I only see (-4,-4) & (6,8) as whole points. Then, you would use the formula: Y2 - Y1*line*X2-X1. Then, if you need to simplify, you can simplify. After that, put it in Point-Slope Form: Y-Y1=m(x-X1) and there is your answer.</em>
Answer:
C. No solution
Step-by-step explanation:
System of Equations:
A) 
B) 
Simplifying and rearranging equation A.
Dividing each term by 3 (common factor for each term) in equation A.
Subtracting both sides by 
Adding 7 both sides.
Adding the above equation to equation B.
+
We have 
which is not true.
Hence the system has no solution. (Answer)
There is a certain order that we follow in doing any mathematical operation:
First we get rid of any operation within brackets, then we do multiplication and divisions and finally we do additions and subtractions.
We need to evaluate: 5x2x(-4) + 6:
So since we have no operations within brackets, then we will do the multiplications first (in their order) then the addition:
5x2x(-4)+6 = 10x(-4)+6 = -40+6 = -34
Now, we need to divide -34 by 2:
-34/2 = -17
The answer is: -17

The answer to your question is:
Step-by-step explanation:
1.-
Data
3.3 x 10 ⁴ pounds of paper
1.5 x 10³ pounds of aluminum
Amount of aluminum / amount of paper = 1.5 x 10³ / 3.3 x 10⁴
= 0.045 times
= 4.5 x 10 ⁻²
2.-
Data
1.2 x 10 ³ text messages in a month
text messages in a year = ?
1.2 x 10³ text messages ------------------- 1 month
x ------------------- 12 months
x = (12 x 1.2 x 10³) / 1
x = 14400 text messages
x = 1.44 x 10⁴ text messages
3.-
Data
distance = 4 x 10⁶ miles I am not sure if the power is 6 or 8
speed = 1.6 x 10³ mi/h
Formula
time = distance / speed
time = 4 x 10⁶ / 1.6 x 10³
time = 2500 h
time = 2.5 x 10 ³ h
