Answer:
x=-7
Step-by-step explanation:
xe^-x+7e^-x=0
factor out the e^-x
e^-x(x+7)=0
e^-x=0, x+7=0
-x=ln(0), x=0-7=-7,
since ln(0) is undefined,
the only solution is -7.
divide
Step-by-step explanation:
But i think I know what you need to do so first count the graph like see where it is pointed at then divide and u get ur answer Again im not sure but maybe
The rate of change is the slope of this line
m = (y2 - y1)/(x2 - x1) = (13 - 5)/(4 - 0) = 8/4 = 2
Answer & Explanation:
Energy is heat. For example, if you boil a cup of water it has more energy than a cup at room temperature. It is considered a physical change because its properties do not change only the state of matter. On the other hand, if wood burns then that is a chemical change because it changes its chemical properties. Please rank as Brainliest if this helps! Thank you!
