Answer: $409.50

ok so, original price 450. 9% discount. discount price is the price after discount, so lets find the discount value. 9% of 450 is 40.5. now subtract that from the original price of 450. 450-40.5=409.50

Answer:

Given

f(x) = 4/(x - 2)

Find

[f(x + h) - f(x)] / h

Solution

[4/(x + h - 2) - 4/(x - 2)]/h =
4/h[(x - 2) - (x + h - 2)]/[(x + h - 2)(x - 2)] =
- 4/h*h/[(x + h - 2)(x - 2)] =
4/[(x + h - 2)(2 - x)]

The diagonals of a quadrilateral QRST intersect at P(-1,3). QRST has vertices at Q(3,6) and R(-4,5). What must be the coordinate

erica [24]

S = (-5,0)

T = (2,1)

Step-by-step explanation:

Step 1 :

Given

Q = (3,6) and R = (-4,5). P = (-1,3)

Let S be (a,b) and T be (c,d)

The diagonals of a parallelogram bisect each other. so in order to ensure that QRST is a parallelogram, P must be the mid point of the diagonals QS and RT.

Step 2 :

P is the midpoint of QS

So we have (3+a) ÷ 2 = -1 and (6 + b) ÷ 2 = 3

=> 3 + a = -2 and 6 + b = 6

=> a = -5 and b =0

So S should be (-5,0)

Step 3 :

P is the midpoint of RT

So we have (-4+c) ÷ 2 = -1 and (5 + d) ÷ 2 = 3

=> -4+ c = -2 and 5 + d = 6

=> c = 2 and d =1

So T should be (2,1)
