Answer 2

we have to compute the subtraction:

\[\Large {5^x} - 10 - \left( {3x + 2} \right) = ...?\]

Answer 3

i don't know michele how to

Answer 4

hint:
\[\Large {5^x} - 10 - \left( {3x + 2} \right) = {5^x} - 10 - 3x - 2 = ...?\]

Answer 5

5^x-3x-10-2 ?

Answer 6

yes! and -10-2=-12

Answer 7

-12=-12

Answer 8

ok!

Answer 9

g(x) –f(x) = 5^x –12 –3x this answer check if right?

Answer 10

yes!
\[\Large {5^x} - 10 - \left( {3x + 2} \right) = {5^x} - 3x - 12\]
that's right!
