Pls help (again) will give brainllest to the first question if right

A = 27.9

B = 11.25

C = 68.6

D = 43.56

Step-by-step explanation:

Each of these questions has two steps, firstly convert the percentage to a decimal, then multiplying that decimal by the other number.  To convert a percentage to a decimal, simply remove the % symbol and divide by 100.  I'm going to presuppose that this has been done in the following answers:

0.45 • 62 = 27.9

0.15 • 75 = 11.25

0.07 • 980 = 68.6

0.22 • 198 = 43.56

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

the answer is 99.
