Answer:

x^-m=1/x^m

1/12=12^-1

also

(x^m)^n=x^(mn)

also (x^m)(x^n)=x^(m+n)

( \frac{1}{12} )^{-2b}(12)^{-2b+2}=12

( 12^{-1})^{-2b}(12)^{-2b+2}=12

( 12^{2b})(12)^{-2b+2}=12

12^{2b-2b+2}=12

12²=12

Create an equation that matches this table

Radda [10]

The equation that matches the given table is

y = 10x + 40

Solution:

General equation of a line : y = mx + c

Let us find the equation of the table.

<u>Common differences of X: </u>

0 – 1 = 1, 1 – 2 = 1, 3 – 2 = 1, 4 – 3 = 1, 5 – 4 = 1

<u>Common differences of Y: </u>

50 – 40 = 10, 60 – 50 = 10, 70 – 60 = 10, 80 – 70 = 10, 90 – 80 = 10

$$m=\frac{\Delta y}{\Delta x}$

$$m=\frac{10}{1}$

m = 10

Substitute m = 10 in general equation of a line

y = 10x + c

To find the constant term, substitute x = 0 and y = 40.

40 = 10(0) + c

40 = 0 + c

40 = c

c = 40

Therefore the equation of a line is y = 10x + 40.

Hence the equation that matches the given table is y = 10x + 40.

Find the markup and the selling price of the following item. Round answers to the nearest cent. A chemistry set costing $27.50,

postnew [5]

Let x be marked up price. We have been given that a chemistry set costing $27.50, marked up 32% on cost.

$x=27.50\times\frac{32}{100}$

$x=27.50\times.32$

$x=8.8$

Therefore, mark up price is $8.80.

Since we know that selling price of any item equals the sum of cost and mark-up price of the item.

Let us find selling price of our chemistry set.

$\text{Selling price of chemistry set}=27.50+8.8$

$\text{Selling price of chemistry set}=36.30$

Therefore, the selling price of the chemistry set is $ 36.30.

VMariaS [17]

Answer:

$- 1.2 , - \frac{1}{2} ,0.44,\frac{7}{3}$

Step-by-step explanation:

We want to arrange the following numbers on the number line in order from least to greatest.

The numbers are:

$0.44, \frac{7}{3} , - 1.2, - \frac{1}{ 2}$

Let us convert everything into decimals to get:

$0.44,2. \bar3 , - 1.2, - 0.5$

Rearranging from least to greatest, we have:

$- 1.2 , - 0.5 ,0.44,2. \bar3$
