Answer: 4 questions
Step-by-step explanation:
16h=10 min
2/3=40 min
Use equation:
1:10=x:40
40=10x
x=40/10
x=4
y = 3x - 1
x - y = -9
Subs y in second equation.
x - (3x - 1) = -9
x - 3x + 1 = -9
-2x = -9 - 1
-2x = -10
x = -10/-2
x = 5
Subs x
y = 3x - 1
y = 3.5 - 1
y = 15 - 1
y = 14
You would add 1 to both sides to get the y alone on the right side. Then it would be y = 1+ -1/2 which is y = 1/2. Hope you understand better!

Answer:
-1, 3, -3
Step-by-step explanation:
I don't see the graph, but you can solve by factoring:

By the factor theorem, the solutions of f(x) are -1, 3, and -3.
