Marat540 [252]

Answer:

-1

Step-by-step explanation:   from the equation,  x-y=8,  make  y the subject of the formulae , this gives - y=  -x +8

divide all through by (-) sign, this gives   y= x - 8

from the last equation above, the slope is the coefficient of x which is 1. since it is perpendicula, the answer is -1

by co efficient, we mean the number multiplying the unknown

Sindi borrowed an amount of money from his
PolarNik [594]

The present value of the loan is R576923.

<h3>What is compound interest ?</h3>

Compound interest is giving the current instalment in terms of the total previous amount.

The formula is given by

A = P(1 + r/100)ⁿ.

Where,

A = Amount, P = Principle, r = rate of interest, n = Time in years.

In case the compound if interest is given every two months that is 6 instalments each year the above given formula will be

A = P{ 1 + (r/6)/100 }⁶ⁿ.

According to the given question

Rate(r) = 7.5%

Time(n) = 6 years

The loan will be paid back in 6 years every second month and it is compounded.

∴ No. of instalments = (12 × 6)/2

= 36.

Now each instalments is of R25000

So, The total amount she has to pay back to his father is

= (25000 × 36)

= R900000.

We know compounding every two months is

A = P(1 + r/100)ⁿ

900000 = P{ 1 + (7.6/6)/100 }³⁶

900000 = P{ 1 + 1.25/100 } ³⁶

900000 = P(1.0125)³⁶

900000 = 1.56P

∴ P = 576923.

What are the coordinates grapging x=3 and y=-2x+1
marusya05 [52]
Answer: -5

First, coordinates are (x, y). You’re x is 3, so all you need to do it plug in x into your algebraic equation to find y. Then just plug both into (x, y) and you have your coordinates.

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