Function rule: a = 20w + 115
Slope: 20
Initial value: 115
------------------------------------------
We start with $115 in the account. This is the initial value. Each week we add on $20.
So we add $20 for 1 week
We add 2*20 = $40 for 2 weeks
We add 3*20 = $60 for 3 weeks
etc etc
In general, we add 20*w dollars for w weeks onto 115 to get a = 20w+115
The slope is 20 because this is the rate of change, ie how fast the account grows. It grows 20 dollars per week.
Step-by-step explanation:
Amount of green clay at the start = 57g + 31g = 88g.
Amouny of green clay used = 88g - 18g = 70g.
Hence 70g of green clay was used during the week.

Answer:
75
Step-by-step explanation:
3×(5) squared becomes 3× 25=75
You do 4x — 2x which equals 2x then you do -2 —4 which equals -6 then you have 2x=-6. so you divide -6/2 and your answer is X=-3. Oh you check by replacing the Xs with -3 and see if the equation is true.
