8.6 is your answer

Step-by-step explanation:

5(3.2+3)-7×3.2=-12.8

Step-by-step explanation:

5(3.2+3)-7×3.2

=5×6.2-7×3.2

=5(-0.8)×3.2

= -4×3.2

= - 12.8

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
