Answer:
k = 11
Step-by-step explanation:
let the points be A(-2,5), B(2,8), C(6,K).
for the points to be collinear slope of line AB maust be equal to line BC.
slope of line AB =
slope of line BC =
therefore
therefore k = 8 + 3
k = 11
Answer:
New amount (decrease) = £17253.53
Step-by-step explanation:
<u>Given the following data;</u>
Amount = £19064.67
Percentage = 9.5%
To find the percentage decrease;
Percentage cost = £1811.14
New amount (decrease) = Original amount - percentage cost
Substituting into the equation, we have;
New amount (decrease) = £19064.67 - £1811.14
<em>New amount (decrease) = £17253.53</em>
A perfect square must be hidden within all of those radicands in order to simplify them down to what the answer is. 
. 
. 
. The rules for adding radicals is that the index has to be the same (all of our indexes are 2 since we have square roots), and the radicands have to be the same. In other words, we cannot add the square root of 4 to the square root of 5. They either both have to be 4 or they both have to be 5. So here's what we have thus far: 
. We can add 
and 
to get 
. That means as far as our answer goes, A = 72 and B = 4, or (72, 4), choice a.
