The expression 3("2m + 5) - 6(4m - 2) can be written in the form am + b. What is the value of a + b?

The value of a + b = 9

Step-by-step explanation:

Step(i):-

Given expression

                     3(2m + 5) - 6(4m - 2)    

                 = 6 m + 15 -24m +12

                 = (6-24) m +27

                = -18 m +27

Step(ii):-

Given that the form  am + b

                             - 18 m + 27

where a=-18 and b = 27

The value of a + b =  - 18 + 27 = 9

Final -

The value of a + b = 9

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
