Answer:

Option C.

Step-by-step explanation:

The given expression is

-\frac{1}{3}-(-\frac{1}{2})

We know that (-)(-)=(+). So, the given expression can be written as

-\frac{1}{3}+\frac{1}{2}

Taking LCM we get

\frac{-2+3}{3\times 2}

\frac{1}{6}

The value of given expression is 1/6.

Two numbers are -\frac{1}{3}\text{ and }-\frac{1}{2}. Mark these point on the given number number.

Now, move from -\frac{1}{2} to -\frac{1}{3} and count the number of jumps.

Number of jumps from -\frac{1}{2} to -\frac{1}{3} is 1.

1 Jump = 1/6

Therefore, the value of given expression is 1/6, therefore the correct option is C.

Given m<br> n, find the value of x and y.<br> (37-18)<br> (8x+12)<br> m<br> (2X+18)<br> n
adelina 88 [10]

Answer:

Step-by-step explanation:

The two inside angles will sum to 180°.

The top to angles are equal.  

Think about this as what if both of the parallel lines were intersected by a perpendicuar line.  Every angle would be a right triangle 90°.  The inside angles will sum to 180° and the opposite angles are again equal.

 (2x + 18) + (8x + 12) = 180

          10x +   30   =   180

                   10x    =   150

                      x  =  15

-------------------------

             (3y - 18)  =  (8x + 12)       x = 15

            (3y - 18)  =  (8(15) + 12)

            (3y - 18)  =  (120 + 12)

            (3y - 18)  =  132

                   3y   =   132 + 18

                   3y   =  150

                     y   =  50

2-6&gt;-3<br> is this correct
romanna [79]

Answer:

im gonna say no and sorry if my answer is wrong

Step-by-step explanation:

subtract 2-6 = -4

now when you work with negative numbers or integers the bigger number will be the closest to the 0 so it's not correct -3 is bigger than -4

Twice a year for 15 years, Warren Ford invested $1,700 compounded semiannually at 6% interest. What is the value of this annuity
-BARSIC- [3]

The value of Warren Ford annuity due is $80,878.21

Define Future Value of an Annuity.

The future value of an annuity is the value of a group of recurring payments at a certain date in the future, assuming a particular rate of return, or discount rate. The higher the discount rate, the greater the annuity's future value.

Given,

Payment fund semiannually is = $1,700

Rate = 6% or 0.06

Time = 15 years

The future value is,

FVₙ =PMT( (1+i/m)ⁿ - 1 ) / (i/m) )

Where,

PMT = $1,700

i = 0.06

m = 2

n = 15 * 2 = 30 periods

Now, plug in the values

FV₃₀ =  PMT ( (1 + 0.06/2)³⁰ - 1 ) / (0.06/2) )

       = $1,700( (1.03)³⁰ - 1 ) / (0.03) )

       ≈ $80,878.2067 or $80,878.21

Hence, the value of Warren Ford annuity due is $80,878.21

One of the tables below contains (x,y) values that were generated by a linear function. Determine which table, and then write th
alexandr402 [8]

Table #1:

Using the first two points (2,1) and (5,3)

You get (x-2)/3 = (y-1)/2

But then the 3rd point (8,7) does not work, so this is not linear.

Table #2

Using the first two points (1,10) and (2,13)

You get x-1 = (y-10) /3

But then the 3rd point (3,18) does not work so this is also not linear.

Table #3

Using the first two points (2,1) and (4,6)

You get x-2 /2 = y-1 /5

And all the other points will work with this, which makes this table linear.

Rewrite the equation to get y = 5/2x-4
