Answer:
x = 6
Step-by-step explanation:
to evaluate this 1/2 (4x + 16) = 20 we need to open the bracket and then cross multiply and finally evaluate for the value of x
1/2 (4x + 16) = 20
4x + 16 = 2 x 20 ............................... using cross multiplication
4x + 16 = 40
combine the like terms together
4x = 40 -16
4x = 24
divide both sides by the coefficient of x
4x/4 = 24/4
x = 6
therefore the value of x in the expression 1/2 (4x + 16) = 20 is evaluated to be equals to 6
Answer:
$ 31.925
Step-by-step explanation:
Final Value = a (1+r)^n
a = initial amount, r = appreciation rate, n = no. of time periods
a = 5 , r = 5% = 0.05 , n = 38
5 (1+0.05)^38
5 (1.05)^38
5 (6.385)
= 31.925
The first thing that shoyuld be noted is that you have linear functions here : straight lines in your graph
