ANSWER IS 8.55
Answer:
The original amount of the mortgage was $66231.45.
Step-by-step explanation:
In order to find the original amount of the mortgage, you can use the following formula to calculate the present value:
PV=FV/(1+r/n)^nt
PV=present value
FV=future value= 775*12*12=111.600
r=rate of interest=0.0440
n= number of compounding periods= 2
t= time in years=12
Now, you can replace the values on the formula:
PV=111600/(1+(0.0440/2))^2*12
PV=111600/(1.022)^24
PV=111600/1.685
PV=66231.45
According to this, the answer is that the original amount of the mortgage was $66231.45.
In this problem, you must change the signs of everything in the parenthesis, which will come to 3x^2 + x - 5x^2 - x + 4. Add like terms, and you will end up with -2x^2 + 4, which is answer choice A. Hope this helped
Answer:
x = 
Step-by-step explanation:
The absolute value always returns a positive value but the expression inside can be positive or negative, that is
x + 4 = 3x - 5 ( subtract 3x from both sides )
- 2x + 4 = - 5 (subtract 4 from both sides )
- 2x = - 9 ( divide both sides by - 2 )
x =
OR
-(x + 4) = 3x - 5
- x - 4 = 3x - 5 ( subtract 3x from both sides )
- 4x - 4 = - 5 ( add 4 to both sides )
- 4x = - 1 ( divide both sides by - 4 )
x = 
As a check
Substitute these values into the equation and if both sides are equal then they are the solutions
| + 4 | = | 
| =
right side = 
- 5 =
left side = right side , thus x = is a solution
check second solution
| + 4 | = | 
| =
right side = 
- 5 = -
right side ≠ left sides, hence not a solution
4 divided by 6 times 5 equals 3.333
