Answer:
I am guessing the 1st one.
Step-by-step explanation:
8x does NOT equal 12 I believe. I am sorry if I am incorrect
Answer:
rate of change= x= 4 y= 20
slope= rise/run= change in y values/change in x values
slope= 20/4
i believe this is right, i could be wrong, i haven't done it in a long time.
An expression for that would be s + 0.05s, or 1.05s.
I dont know how to solve it but since the answer shows as 6 and -7, if you plug it in as x values, one tiem as 6 and second time as -7 it doesnt equal 42
