Answer: x = 0, y = 7
-x+y=7
add x to both sides
y=x+7
plug this in for y in the other equation
6x-(x+7)=-7
simplify
6x-x-7=-7
simplify
5x-7=-7
add 7 to both sides
5x=0
divide both sides by 5
x=0
plug in to one of the equations to find y
-(0)+y=7
y=7
Therefore, x=0 and y=7.
Hope this helps!
Using the chain rule: The derivative of e^u is (e^u)(u'). Notice that e^u is rewritten exactly as is and then multiplied by the derivative of the exponent.
Let u=2x. So u'=2
So the derivative of e^u is e^(2x)*2 This can also be written as 2e^(2x).
Answer: C. framing
Step-by-step explanation:
People tends to decides on options based on the type of framing presented to them. Framing effect is a cognitive bias where people decide on options presented to them based on whether it's presented with positive or negative connotations and remarks. In the case above, the reaction of people to the same idea when presented positively and negatively was different. It implies that the framing of the same idea may influence people's decision
Because when you do that ...
-- you're starting with a piece that's less than ' 1 ', and
-- you're calculating a piece of it that's less than the whole original piece.
