2x²+8x=x²-16

2x²-x²+8x+16=0

x²+8x+16=0

D=b²-4ac

=8²-4×1×16

=64-64

=0

x= -b+VD / 2a

=-8+V0 /2

= -8/2

=-4

The price of a home is $120,000. The bank requires a 10% down payment and two points at the time of closing. The cost of the hom
rusak2 [61]

Answer:

The amount of the loan is $120,000 -10% + 2% = $110,400, assuming the "points" are added to the financed amount.

I find that the monthly payment will be

$848.89. There will be 360 such payments over 30 years, for a total payment amount of $30The amount of the loan is $120,000 -10% + 2% = $110,400, assuming the "points" are added to the financed amount.

R = Pi/[1 - (1+i)^(-n)] where

P = 110,400

R = the monthly payment

i = 8.5/[100(12)] = .007083...

n = 30(12) = 360 yielding

R = $848.88 per month.

Therefore, the total interest paid is 360(848.88) - 100,400.

5,600. Subtract the original principle (110,400) from that to get the interest paid.

hopes this helps :]

The value of the expression -2 xy for x = -4.7 and y = 0.2 is _____.
sergeinik [125]

The value of the expression -2xy for x = -4.7 and y = 0.2 is 1.88. Thus option number 3 is correct.

<u>Solution:</u>

We have been given an expression that is -2xy and have been asked to find its value for the given values of x and y

The given values of x and y are -4.7 and 0.2 respectively.

To find the value of the expression for the given values of x and y we substitute the values of x and y in the given expression and solve it as follows:

Given expression = -2xy

\begin{array}{l}{=-2(-4.7)(0.2)} \\\\ {=9.4 \times 0.2} \\\\ {=1.88}\end{array}

Hence the option number 3 is correct.

Answer:

The three expressions are the first option, the third option, and the forth option

Step-by-step explanation:

I don't really know how to explain my math lol but I solved 5(1/3x+7)-3(1/2x-), and got x, and plugged in x to the equation. I got my answer, and plugged in x to the rest of the equations and the first one, third one, and fourth ones were the ones that had equal answers. You may want to check my math though because i am not the best but that is what I got.
