10^9 (Ten to the power of nine)
First of all you have to make them equal to each other. What I mean is the following
3x+20=2x+40
Then you should just solve for x
Answer:
108 = x
Step-by-step explanation:
multiple both sides by 24 and simplify
9 x 24 = 216/2=x
108 = x
Answer:
60
Step-by-step explanation:
In the function, the growth factor is "a", the base of the exponent. When the exponent is increased by 1, the value is multiplied by "a".
f(7) = a·f(6) = 4·15
f(7) = 60
_____
As you know, the exponent signifies repeated multiplication. So, an increase of 1 in the exponent means the base is part of the product one more time:
a^6 = a·a·a·a·a·a
a^7 = a·a·a·a·a·a·a = a·(a^6)
