Let g(x) = 3x + 2 If g(x) = 11 find x
1 answer:
Answer:
See below:
Step-by-step explanation:
So, for starters, g(x) is just a fancy way of saying that it is a function, it's basically used as and you can usually use g(x) or y whenever you want unless its a special situation.
So we can replace g(x) with y as there aren't any other functions we need to deal with.
y = 3x + 2
y = 11
Now that its simplified, we can see its a simple problem
After combining, we get 11 = 3x + 2
After solving, we get x = 3

Answer:
y = -5x Y8
Step-by-step explanation:
Parallel lines have the same slope.
Your function is
y = 9 − 5x = -5x+ 9
slope = -5
The parallel line
The line must have slope = -5 and include (0, 8), so
8 = -5×(0) + b
8 = 0 + b
b = 8
The equation for the parallel line is
y = -5x + 8
In the diagram below, the red line is the graph of y = 9 -5x.
The parallel blue line is the graph of y = -5x + 8.
