Answer:
AB = DF (Proved below)
Step-by-step explanation:
Here,
CE = CD + DE [since D is a point over CE]
= DE + EF [ Since, CD = EF (given)]
= DF [ Since, E is a point over DF] ---------------(1)
Again,
AB = CE (given) ------------------------(2)
So from (1) and (2),
AB = CE = DF
⇒ AB = DF (Proved)
Answer:Suppose the cost stock is x and the cost of fund is y.
Total cost of Nora's portfolio:
100x+200y=3800.....i
Total cost of Erin's portfolio
300x+50y=5350...ii
solving the simultaneous equation by elimination method we proceed as follows:
multiplying eqn by 3 and subtracting ii we get:
550y=6050
thus
y=6050/550
y=11
next, multiply ii by 4 and subtracting i we get:
1100x=17600
x=16
thus the cost of Technology stock was $16 and the cost of mutual fund was $11
Step-by-step explanation:
Answer:
x=7, y=9. (7, 9).
Step-by-step explanation:
-3x+y=-12
5x-2y=17
---------------
y=-12-(-3x)
y=-12+3x
y=3x-12
5x-2(3x-12)=17
5x-6x+24=17
-x+24=17
-x=17-24
-x=-7
x=7
y=3(7)-12
y=21-12
y=9
Answer: Demand Deposit
Step-by-step explanation:
A demand deposit account (DDA) consists of funds held in a bank account from which deposited funds can be withdrawn at any time, such as checking accounts. DDA accounts can pay interest on a deposit into the accounts but aren't required
