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
Answer:
No, because the median test score decreased 5 points.
Step-by-step explanation:
The middle line is is the median so, if the pre-test is 60 and the post-test is 55 then there is a 5 point difference.
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.

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
