Solve the simultaneous equations 4x+8y=-4 2y-5x=23
ad-work [718]

Answer:

x = -4,  y = 3/2

Step-by-step explanation:

simplify the 1st equation by dividing each term by 4 to get:

x + 2y = -1

-5x + 2y = 23

Subtract to get: 6x = -24

x = -4

find 'y':    2y - 5(-4) = 23

               2y + 20 = 23

               2y = 3

                y = 3/2

How much money will you have at the end of one year if interest is compounded semiannually at 10% on a $600 deposit?
Masja [62]
The formula required to answer this is:
A=P(1+\frac{r}{n})^{nt}
where  A is the amount of the principal P after n compounding periods per year at r interest rate (as a decimal fraction).
Plugging in the given values, we get:
A=600(1+\frac{0.1}{2})^{2\times1}=661.5
Rounding to the nearest dollar, we get $662.00. Therefore a is the best answer choice.
