Answer:
I think it's either A or B
Step-by-step explanation:
Parallel lines, have the same slope, so the slope of the line through 0,0 and -2,-12, is the same as for the line running through (6/5,-19.5) as well, so what is it anyway?

so, we're looking for the equation of a line whose slope is 6, and goes through (6/5,-19/5)
50 cm = 1/2 m
3 m ÷ 1/2 m = 6
It will take him six days.
Answer:
180 - 111= 69
Step-by-step explanation:
This problem is quite simple, I'll try to help you understand why it is~
f(x) is NOT f times x, but it is f, the function of x.
This means that the value of f depends on the value of x. f(1) means the value of the function, f, when x = 1.
Thus, f(3) is the value of the function, f(x), when x = 3. According to the table, f(x) is 1 when x is 3. That should be your answer.
Please do let me know if you still do not understand.
Happy Studying~
