Last year, Chang opened an investment account with S8500. At the end of the year, the amount in the account had decreased by 6.8% How much is this decrease in dollars? How much money was in his account at the end of last year?

Decrease in amount:

Year-end amount:

Decrease in amount= $578

Year-end amount= $7,922

Step-by-step explanation:

0.068=x/8500

Isolate x to multiply 0.068 by 8500= 578 which is the decrease in dollars.

so, 8500-578= $7,922 is how much money was in his account at the end of last year.

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
