R118 212, 21 Question 16
A family takes out an R800 000 mortgage from the bank to buy a new home. The bank charges
interest at an annual rate of 14% compounded monthly over 20 years. How much of the
outstanding balance on the loan will the family still owe at the end of the first year?
1. R772 687,39
2. R783 083,94
3. R792 129,68
4. R799 385,17​

3x + 4y -25 =0 represents the amount of change sianna should recieve

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52

step-by-step explanation:

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0
