Answer:

we will take the examples:

3.683, 4.683 , 5.683 , 6.683 and 7.683

Expanded form:

3.683=3+\frac{6}{10}+\frac{8}{100}+\frac{3}{1000}

4.683=4+\frac{6}{10}+\frac{8}{100}+\frac{3}{1000}

5.683=5+\frac{6}{10}+\frac{8}{100}+\frac{3}{1000}

6.683=6+\frac{6}{10}+\frac{8}{100}+\frac{3}{1000}

7.683=7+\frac{6}{10}+\frac{8}{100}+\frac{3}{1000}

Word form:

3.683  will be written as three and six hundered eighty three thousandths

4.683  will be written as four and six hundered eighty three thousandths

5.683  will be written as five and six hundered eighty three thousandths

6.683  will be written as six and six hundered eighty three thousandths

7.683  will be written as seven and six hundered eighty three thousandths.

What is the equation of the line that passes through the point (1,3) and is perpendicular to the line 2x+3y=15?
Snezhnost [94]

Answer:

  3x -2y = -3

Step-by-step explanation:

The perpendicular line will have a slope that is the negative reciprocal of the slope of the given line. The constant in its equation will ensure the line goes through the desired point.

__

<h3>form of the equation</h3>

The equation for the given line is in standard form:

  ax +by = c . . . . . where a>0 and a, b, c are mutually prime

The equation of the perpendicular line can be written ...

  bx -ay = c' . . . . . where c' is a new constant

For a=2, b=3, the equation of the perpendicular will be ...

  3x -2y = c'

<h3>constant</h3>

The constant is chosen so the given (x, y) values satisfy the equation.

  3(1) -2(3) = c' = -3

<h3>equation</h3>

Then the equation of the perpendicular line through point (1, 3) is ...

  3x -2y = -3
_____

<em>Additional comment</em>

For the standard-form equation shown, the slope of the line is ...

  m = -a/b

The negative reciprocal slope is ...

  -1/m = -1/(-a/b) = b/a

This is the original slope equation with a and b swapped, and one of them negated.

__

The graph confirms the new equation.

F(x)=-x^2+7x-13 {Find }f(-3) it's not -25....so if that's ur answer..it's wrong
IRISSAK [1]

Answer:

-43

Step-b-y-step explanation:

f(x)= -x^2+7x-13  so

f(-3)= - (-3)^2 + 7(-3) - 13

= -9 - 21 - 13

= -43.

Solve for x ? I don’t understood
kvasek [131]

Answer:

x=8

Step-by-step explanation:

In this parallelogram, the opposite sides are equal

PN = LM

5x+7 = 9x-25

Subtract 5x from each side

5x-5x+7 = 9x-5x -25

7 = 4x-25

Add 25 to each side

7+25 = 4x-25+25

32 = 4x

Divide each side by 4

32/4 = 4x/4

8 =x
