What is x+9=2(x_1)^2 in the form of ax^2+bx +c=0

Answers

Answer 1

Answer: x + 9 = 2(x - 1)^2
x + 9 = 2(x^2 - 2x + 1)
x + 9 = 2x^2 - 4x + 2
2x^2 - 4x + 2 - x - 9 = 0
2x^2 - 5x -7 =0

Nell's mortgage is $50,150 at 10 percent for 30 years. What is her monthly payment if she must pay $8.78 points per $1,000?a) $440.32
b) $439
c) $442.95
d) $385.89

Answers

Answer:

The correct option is a.

Step-by-step explanation:

It is given that Nell's mortgage is $50,150 at 10 percent for 30 years and she must pay $8.78 points per $1,000.

EMI on $1000 is $8.78, so EMI on $1 is

$\text{EMI on }\$1=(8.78)/(1000)=0.00878$

EMI on $50150 is

$\text{EMI on }\$50150=0.00878* 50150=440.317\approx 440.32$

Therefore the correct option is a.

The right answer for the question that is being asked and shown above is that: "d) $385.89." Nell's mortgage is $50,150 at 10 percent for 30 years. Her monthly payment if she must pay $8.78 points per $1,000 is that of d) $385.89
