Answer:

Step-by-step explanation:

Determine the defined range

Take the logarithm of both sides of the equation

Convert the constant into a logarithmic with base 10

Using loga(x)+ loga(y)=loga(xxy)

Evaluate the power

Since the base is based of the logarithmic are the same , set the argument equal

Divide both sides of the equation by 100

Check if the solution is in defined range

Answer: 21/100

Answer/Step-by-step explanation:

Given:

Bracelets - $3

Necklaces - $6

To Find:

Complete the patterns in the first two columns for the cost of 0,1,2,3 and 4 pieces of jewelry. Write the ordered pair for the corresponding terms in the third column. Then graph the ordered pairs.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Solve: Complete the patterns in the first two columns for the cost of 0,1,2,3 and 4 pieces of jewelry.

Bracelets: Necklaces:

0 = $0 0 = $0

1= $3 1 = $6

2=$6 2 = $12

3=$9 3 = $18

4=$12 4 = $24

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Solve: Write the ordered pair for the corresponding terms in the third column.

Ordered Pair -

Two numbers written in a certain order.

Usually written in parentheses like this:

(12,13)

Where they cross over is the "0" point,

we measure everything from there.

The X Axis runs horizontally through zero

The Y Axis runs vertically through zero

(x, y )

Since it asking for Write the ordered pair for the corresponding terms in the third column.

Thus,

- Number of jewelry to cost -

we have:

Bracelets ⇒ ( 3, 9)

Necklaces ⇒ (3, 18)

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Then graph the ordered pairs.

When you are finding the slope of a line using two points, it doesn't matter which point you choose to be (x1,y1) and which poin

mariarad [96]

Typically if it is a linear function then it doesn't matter. However if it is a quadratic, cubic, and so on and so forth....( $x^{2},x^{3},x^{4}$ ) you may want to used the distance formula if you are not given any other points (with the exception of the vertex, asymptote or roots... etc).

PLZ HELP

Answer: No, 40 months isn’t reasonable.

Step-by-step explanation:

For Shellie: 40*3 = 120 cm in 40 months

For Carley: 40*2 = 80cm in 40 months

Next we add the amount of hair they have already to the amount of centimeters would grow.

Shellie: 120+10 = 130cm

Carley: 80+20 = 100cm

So if the girls wanted to cut their hair at the exact length, 40 months isn’t a reasonable solution.
