for the columns where is less than or equal zero, use the first line of the function to calculate the value of f(x)

for every x greater than zero, use the second line to determine the value

hope this helps and gives some insight what to do.
if there are open questions left, feel free to ask them in the comments
have a beautiful day

Answer:

Step-by-step explanation:
Answer:
The 5 in the () is what the x is
Step-by-step explanation:
3(5)+2=17
49^(3/2)
This is the same as (sqrt49)^3
7^3 = 343
There are 187 nickels and 66 dimes in the jar.
Step-by-step explanation:
Given,
Total coins = 253
Value of coins = $15.95 = 15.95*100 = 1595 cents
Value of each nickel = 5 cents
Value of each dime = 10 cents
According to given statement;
x+y=253 Eqn 1
5x+10y=1595 Eqn 2
Multiplying Eqn 1 by 5

Subtracting Eqn 3 from Eqn 2

Dividing both sides by 5

Putting y=66 in Eqn 1

There are 187 nickels and 66 dimes in the jar.
