Answer:

Solve by substitution;

2x +4y =8 ...(1)

$2x + 4y = 8 \\ \\ 4y = 8 - 2x \\ \\ y = \frac{8 - 2x}{4} \\ \\ y = 2 - \frac{x}{2}$

We substitute y into the second equation.

2x + 2y=2 ... (2)

$2x + 2y = 2 \\ \\ 2x + 2(2 - \frac{x}{2} ) = 2 \\ \\ 2x + 4 - x = 2 \\ \\ x + 4 = 2 \\ x = 2 - 4 \\ x = - 2$

And we substitute x into the equation y .

$y = 2 - \frac{x}{2} \\ \\ y = 2 - \frac{( - 2)}{2} \\ \\ y = 2 + 1 \\ y = 3$

(x,y) —> (–2 , 3 )

Answer:

Muliple choice A.

Step-by-step explanation:

Here, we have two sets that need to be subtracted from eachother. So, first we start off like we're reading a book. From top to bottom, from left to right. And we need to match up the numbers together to subtract. (i.e. the top left from both set A and B will be 5 and 1, so we subtract these. And we do that for all the numebrs.

$1000 is invested in an account at interest rate r=0.045, compounded continuously. Find the time required for the amount to doub

Answer:

The formula you'll need is:

Years = ln (total / principal) / rate

ln means natural log

Years = ln (2,000 / 1,000) / .045

Years = ln (2) / .045

Years = 0.69314718056 / .045

Years = 15.4033
