45 because you do 210-120 which is 90. 90÷2 is 45.
-JZ
2.1 x 4/0.5
2.1 x 4 = 8.4
8.4/0.5 =
16.8
(fog)(x)= f(g(x))=f(2)= 2
This is incorrect because 2 + 5.8 = 7.8. And 7.8 does not equal 6. 2 + 4 = 6 is the correct answer. This could be represented by this:
2 + x = 6.
Subtract two from both sides to get:
x = 4.
When substituted back into the equation:
2 + (4) = 6.
Answer:
Start at -4 and go up to -1.
