Answer:
(f+g)(x) = 13x + 3
Step-by-step explanation:
Rewrite f(x)=2x+7 and g(x)=11x-4 in columns, as follows:
f(x)=2x+7
+g(x)=11x-4
----------------
Now add each column separately.
f(x)+g(x) = (f+g)(x) ("the sum of functions f and g")
2x + 11x = 13x, and, finally, 7-4 = 3.
Therefore,
f(x)=2x+7
+g(x)=11x-4
----------------
(f+g)(x) = 13x + 3
-3 it’s the rise over run I believe & because it’s going down it’s negative
Answer:
y=9x+1.6
Step-by-step explanation:
bring the 10.6 over by adding it to both sides
Multiply 4 and 30. If the answer is 120, then you are correct.
