For this case, the first thing you should do is observe the intersession of the lines.
The solution of the intersection of the lines will be given by an ordered pair of the form:
(x, y)
So, for the next ordered pair:
(x, y) = (0, 8)
We have the lines that intersect are:
Line A
Line C
Answer:
A pair of equations that has (0, 8) as its solution are:
Equation A and Equation C

By looking at the graph, it seems Equation A and Equation C both intersect at (0, 8). So the first answer is correct.

How much to the nearest dollar should you deposit in a savings account at 2.5% annual simple interest in order to have a balance

Aneli [31]

Answer:

The amount we have to deposit in a savings account x = $ 17777.78

Step-by-step explanation:

Amount = $ 20000

R = 2.5 %

Time = 5 years

Take principal amount = x

Simple interest earned in five years

S.I. = $\frac{P R T}{100}$

$S.I. = \frac{P (2.5)(5)}{100}$

$S.I. = \frac{x}{8}$ ------- (1)

We know hat total amount is given by

Total amount = principal amount + simple interest

A = x + S.I.

$A = x + \frac{x}{8}$

$A = \frac{9x}{8}$

Given that the total amount after 5 years is = $ 20000

$\frac{9x}{8} = 20000$

x = $ 17777.78

This is the amount we have to deposit in a savings account.

Answer:

I think that the answer would be C because you have to multiply the term at the top. This would mean you would not do C. Sorry if this is wrong. At least you have your eliminating process now. lol so doing C is out of the box, which makes C your answer.

Factor out the coefficient of the variable 1/2q plus 5/2

Iteru [2.4K]

I believe you do it like this:
1/2 Q+5/2
divide 1/2 into each term
to divide multiply by the reciprocal
1/2 x2/1= 1
5/2 x 2/1=5

1/2(Q+5)
