The lines are parallel.

In order to figure this out, let's start off by simplifying both equations as much as we can:
2y = 16 + 4x
Divide by 2
y = 2x + 8

Remember that the slope of that equation is '2' since 'm' in the equation y = mx + b represents slope.

Simplify the next equation:
6y - 30 = 12 x
6y = 12x + 30
Divide by 6:
y = 2x + 5

As you can tell, this line also has a slope of 2.
Parallel lines is defined as two lines that have the same slope. Knowing this, we can infer that these two lines are parallel.

(3/5 + -1/4)/(7/10)

get a common denominator of 20

3/5 * 4/4 =12/20

-1/4 * 5/5 = -5/20

7/10 *2/2 = 17/20

replace

(12/20 - 5/20)/(14/20)

add the top

(7/20)/(14/20)

copy dot flip

7/20 * 20/14

7/14

You can use the formula P=A(i/1-(1+i)-n) monthly payment on a loan of A dollars that is paid back in equal monthly payments over

Dafna11 [192]

Answer:

$48.54

Explanation:

We must express the interest rate on a monthly basis.

i = 8 %/yr = 0.6667 %/mo = 0.006 667

A = $4000

n = 120 mo

$P = A(\frac{i}{1-(1+i)^{-n}})$

$P = 4000(\frac{0.006667 }{1-(1+0.006667)^{-120}})$

$P = \frac{26.67}{1-0.006667^{-120}}$

$P = \frac{26.67}{1-0.4505}$

$P = \frac{26.67}{0.5495}$

P = 48.531

The banks round up the numbers, so Seki’s monthly payment is $48.54.

May I know the values of x and y of the following equation?<br>(5-3i)(x-yi) = 3(x+2yi)+1-2i

gogolik [260]

Answer:

(x, y) = (17/31, 1/31)

Step-by-step explanation:

Simplify the given equation, then equate real parts and equate imaginary parts. This will give you two equations in the two unknowns.

<h3>simplify</h3>

(5 -3i)(x -yi) = 3(x +2yi) +1 -2i

5x -5yi -3xi +3yi² = 3x +6yi +1 -2i

(5x -3y) +i(-5y -3x) = (3x +1) +i(6y -2)

<h3>equate real, imaginary parts</h3>

This resolves to the two equations ...

5x -3y = 3x +1
-5y -3x = 6y -2

<h3>solve the system</h3>

Putting these equations into general form gives ...

2x -3y -1 = 0

3x +11y -2 = 0

Using the "cross multiplication method" to solve these equations, we get ...

x = ((-3)(-2) -(11)(-1))/(2(11) -3(-3)) = 17/31

y = ((-1)(3) -(-2)(2))/31 = 1/31

The values of x and y that satisfy this equation are ...

(x, y) = (17/31, 1/31)
