Question

k = 13+ -2
k = 13.3 - 2
=

g = -5(3) + 13
g = -15 + 13
g = -2

Explanation:

For calculating \( k \):

Step1: Identify the expression for \( k \)

The expression is \( k = 13.3 - 2 \) (assuming the '13+' was a typo and should be 13.3 or 13, here we use 13.3 as per the written number).

Step2: Perform the subtraction

\( k = 13.3 - 2 = 11.3 \) (if the '13+' was meant to be 13, then \( k = 13 - 2 = 11 \))

For calculating \( g \):

Step1: Identify the expression for \( g \)

The expression is \( g = -5\times3 + 13 \) (assuming \( r(3) \) means \( r = 3 \) or the input to the function is 3, so we calculate \( -5\times3 \) first).

Step2: Calculate \( -5\times3 \)

\( -5\times3 = -15 \)

Step3: Add 13 to the result

\( g = -15 + 13 = -2 \) (note: there was a double negative or typo in the original writing where it said \( g = -2 \) but the calculation here gives -2, maybe the original had a sign error, but following the arithmetic: \( -15 + 13 = -2 \))

Answer:

s:
If \( k = 13.3 - 2 \), then \( k = 11.3 \); if \( k = 13 - 2 \), then \( k = 11 \).
For \( g \), \( g = -2 \)
