An appliance is for sale at either (a) P15,999 cash or (b) on terms, P1,499 each month for the next 12 months. Money is 9% comp

frutty [35]

Answer:

Cash price

Step-by-step explanation:

The computation is shown below:

The Interest rate per month (r) = (9% ÷ 12) = 0.75%

Now Present value of the monthly payment is

= PMT × {[(1 + rate of interest)^number of years - 1] ÷ rate of interest}

= 1,499 × {[(1 + 0.75%)^12 - 1] ÷ 0.75%}

= 18,748.89

And the cash price is 15,999

So, the cash price would be lower

Write the equation of a line that is

il63 [147K]

Answer:

Y= 3x-7

Step-by-step explanation:

Since the line is parallel , the slope is same i.e. 3 .

now the equation should be y= Mx + b where m is the slope and c is the y-intercept

plugging the value of m=3 and ( 3,2) into the equation

2= 3(3) + c

2= 9+ c

c= -7

hence the equation of the line is y=3x-7

Given a line with a slope of1/2 and a point(6,5) which lies on that find an equation to represent that line

kondor19780726 [428]

Answer:

The equation of the line is given as 2 y - x = 4.

Step-by-step explanation:

Here, the slope of the given line = 1/2

The point on the line is (x0,y0) = (6,5)

Now, by POINT SLOPE FORMULA:

The equation of line with (x0,y0) and slope m is written as:

(y - y0) = m (x-x0)

So, here the equation of line is given as

$( y- 5) = \frac{1}{2} (x-6)\\\implies 2( y-5) = ( x-6)\\or, 2y - 10 = x - 6\\\implies 2y - x = 4$

Hence the equation of the line is 2 y - x = 4.

2x + y = -4<br> 5x - 3y = 1<br><br> Solve with elimination method

Ivanshal [37]

Answer:

For the first equation the answer for "X" will be,

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

if you want me to solve for y instead then the answer will be,

$y = - 4 - 2x$

for the second equation the answer for "X" will be,

$x = \frac{1 + 3y}{5}$

If you want me to solve for y instead then the answer will be,

$y = - \frac{1 - 5x}{3}$
