I would go about solving this by elimination because the x variables are already the same so all you would have to do is change one equation to the opposite signs and add them, so it would look like:
7y + 5x = 19
+ -3y - 5x = -7
-------------------
4y=12
y=3
Answer:
Step-by-step explanation:
<u>Given</u>
To find f(q+1),
<u>substitute x with q+1 in the given equation:</u>
- f(q + 1) = 6(q + 1) + 7 = 6q + 6 + 7 = 6q + 13
Answer:
If my memory of functions serves me right it is Graph B.
