Answer:
See explanation below
Step-by-step explanation:
a + b = 0
The additive identity establishes that if you add a real number to zero, then you get the same real number back.
The additive inverse of a number x is -x (because x + (-x) = 0)
a+b = 0, but by the additive identity we can add -a (the additive inverse of a) to both sides of the equation:
a + b - a = 0 - a
a + b - a = -a (Now, using the Cancellation property we can cancel a and -a on the left side)
b = -a
In the 2nd digit is worth 300. In the 3rd digit it is worth 30.
Answer: 13
Step-by-step explanation:
Area = 165
Area of square is :
Area = length × length
Let length be l
165 = l ^ 2
Square both side
l = sqrt(165)
l = 12.85
l = 13 to the nearest whole number
Plugging the values into a table on desmos, it clearly follows an exponential equation as shown by the equation of best fit. Therefore, the relationship is exponential.
