Answer: Rational
Step-by-step explanation:
21
is rational because it is
times 21 which is 65.9734457254 and numbers that terminate or repeat are rational.
(-2/3) / (5/4) =
-2/3 * 4/5 =
-8/15 <=
We can assume that the y-intercept for this equation is 125, because that would be how much Anna already has saved before she begins saving money from her allowance. Then, we know that Anna adds $2 to her savings each day from the problem, so we know that the slope will be positive 2 then.
Equation:
y = 2x + 125
