Answer:
a non linear function to the algrithm
Step-by-step explanation:
magth
Answer: c) 3
<u>Step-by-step explanation:</u>
Plug in y = -9 and the given x-value to see if it makes a true statement.
a) -4.5 falls in the piecewise function x < -3 --> y = -x
y = -x
-9 = -(-4.5)
-9 = 4.5 FALSE
b) -3 falls in the piecewise function -3 ≤ x ≤ -2 --> y = 2x
y = 2x
-9 = 2(-3)
-9 = -6 FALSE
c) 3 falls in the piecewise function x > -2 --> y = -x²
y = -x²
-9 = -(-3)²
-9 = -9 TRUE
d) 9 falls in the piecewise function x > -2 --> y = -x²
y = -x²
-9 = -(9)²
-9 = -81 FALSE
The sum of the given decimal numbers is -7.68
<h3>Sum of decimal numbers</h3>
Decimal numbers are numbers that contains decimal points. Given the expression below;
4.62 + (−12.3).
Convert to fraction to have:
4.62 + (−12.3) = 462/100 - 123/10
Find the LCM
4.62 + (−12.3) = 462-1230/100
4.62 + (−12.3) = -768/100
4.62 + (−12.3) =-7.68
Hence the sum of the given decimal numbers is -7.68
