Answer:
Elimination:
-4x - 2y = -18 -4x - 2y = -18
x + 3y = 8 | ×4 ------> <u> 4x + 12y = 32 </u> +
10y = 14
y = 1,4
x + 3y = 8
x + 3(1,4) = 8
x + 4,2 = 8
x = 3,8

Answer:
find the y-value corresponding to x=3
Step-by-step explanation:
Locate x=3 on the x-axis. Follow a vertical line from that point to the graph of the function. Read from the graph the y-value of the point of intersection of that vertical line and the function. That y-value is f(3).
