Answer:

x=5,y=6

Step-by-step explanation:

given, 6x+2y=42................(1)

-6x+12y=42..............(2)

adding (1) and (2)

6x+2y-6x+12y=42+42

14y=84

y= $\frac{84}{14}$

y=6,

y=6 put in equation (1)

6x+2times{6}=42

6x=42-12=30

x= $\frac{30}{6}$

x=5

Anthony wants to buy CD for $400 that earns 2.5% APR and is compound quarterly. The CD matures in 3 years. Hi interest earned wi

lukranit [14]

Answer:

The correct option is: B. $30.00

Step-by-step explanation:

The formula for compound interest is.......

$A=P(1+\frac{r}{n})^n^t$ , where A= Final amount, P= Initial amount, r= rate of interest in decimal form, n= number of compounding in a year and t= time duration in years.

Anthony wants to buy CD for $400 that earns 2.5% APR and is compound quarterly and the CD matures in 3 years.

So here, $P= 400, r=2.5\%=0.025, t= 3$

As the CD is compounded quarterly, so here $n= 4$

Plugging these values into the above formula......

$A= 400(1+\frac{0.025}{4})^(^4^*^3^)\\ \\ A= 400(1+0.00625)^1^2\\ \\ A=400(1.00625)^1^2\\ \\ A= 431.053...$

So, the amount of total interest earned $= (\$431.053...-\$400)=\$31.053... \approx \$30.00(Approximately)$

Line the slope and y-intercept to graph each equation below

Leno4ka [110]

Answer:

<h2>The graphs in the attachments.</h2>

Step-by-step explanation:

The slope-intercept form of an equation of a line:

$y=mx+b$

m - slope

b - y-intercept

We have the equations of the lines in the general form Ax + By + C = 0.

Convert to slope-intercept form:

$2x-2y+5=0$ subtract 2x and 5 from both sides

$-2y=-2x-5$ divide both sides by (-2)

$y=x+\dfrac{5}{2}$

$y-3=0$ add 3 to both sides

$y=3$

To draw a line we need only two points. Choice any two x values and calculate the y values.

$for\ x=0\to y=0+\dfrac{5}{2}=\dfrac{5}{2}=2.5\to(0,\ 2.5)\\\\for\ x=-2\to y=-2+\dfrac{5}{2}=-2+2.5=0.5\to(-2,\ 0.5)$

$y=3$

It's a horizontal line.

I can't seem to find the answers or understand how this works.

Zepler [3.9K]

Answer:

m = 5

n = 12

Step-by-step explanation:

Opposite sides in a parallelogram are equal

so:

m+1 = 6

m = 6-1

m = 5

n is opposite to 12 so n = 12
