Okay so from my understanding this is supposed to be done like y=mx+b so for 2a. 8= -2(3)+b then 8= -6+b you add the 6 to both sides and get 14=b
After 4 weeks you have put 4 x 200 = 800 into the account, if the balance is 1700 you must have had 1700-800 = 900 in the account as an opening balance.
<span>Balance on the account = 900 + 200 x 4 = 1700 </span>
<span>For x weeks </span>
<span>y = 900 + 200 x </span>
<span>y-900 = 200 x </span>
<span>subtract 800 each side </span>
<span>y-900-800 = 200x - 800 </span>
<span>y-1700 = 200(x-4)</span>

X=-11.5 and y=10.5.Thae two values are the answers.
Answer:
x=40
Step-by-step explanation:
The sum of the angles of a triangle add to 180
x+102+38 = 180
Combine like terms
x + 140 = 180
Subtract 140 from each side
x+140-140 = 180-140
x = 40
