Step-by-step explanation:
In general, the slope intercept form assumes the formula: y = mx + b. m is the slope (lesson on slope ) mnemonic : 'm' means 'move' b is the y -intercept ( lesson on the y-intercept ) mnemonic : 'b' means where the line begins.
22. Because m=4, we can plug 4 into the equation so that it reads (5*4 + 2). Multiplication comes first, so the equation becomes (20+2). 20 plus 2 is equal to 22.

Step-by-step explanation:
Use the half life equation:
A = P (½)^(t / T)
where P is the initial amount, t is time, and T is the half life length.
Given P = 40, t = 9, and T = 21:
A = 40 (½)^(9 / 21)
A ≈ 30
