I believe it might be d but I'm not sure, sorry hope I could help
3. Reduction
For example,
11x - 3y = 69
-3x + 3y = 3
___________
8x + 0y = 72 => x = 72/8 => x = 9 => -27 + 3y = 3 => 3y = 30 => y = 30/3 => y = 10.
Answer:
x = -2
Step-by-step explanation:
f(x) = 3x - 5
= 3(1) - 5
= 3 - 5
x = -2
Answer:
Step-by-step explanation:
8x-1+6x+13=180 degree(being co interior angle)
14x=180-12
x=168/14
x=12
If you plug in f(-1) you get 66
