A = P + Prt
A = P/P + Prt/P
A = P(1 + rt)
A/P = P(1 + rt)/P
A/P = 1 + rt
A/P - 1 = 1 - 1 + rt
A/P - 1 = rt
(A/P - 1)/t = rt/t
(A/P - 1)/t = r
Thus r = (A/P - 1)/t.
Answer:
Slope, after x stays the same so in this case it would be 2x+b
Step-by-step explanation
To find b, just substitute the x and y values for the ones given. Ex.
6= 2(-3)+b
Then solve for b.
Answer: a constant is a fixed number in an expression. For example x+5=9. The constants are 5 and 9 since it’s a fixed number. Since it says x is a constant it means it can only be one answer.
I would have to go with C and D on this one.
