Find the equation of the line show
nexus9112 [7]

Answer:

Equation : y = 2x + 3

Step-by-step explanation:

By considering any two coordinates from the line.

For example: I choose (0, 3) and (2, 7)

<em><u>slope :</u></em>

<em><u /></em>slope = \frac{y_2 - y_1}{x_2 - x_1} = \frac{7-3}{2-0} = \frac{4}{2} = 2<em><u /></em>

<em><u>Equation :</u></em>

(y - y_1) = m (x - x_1)\\\\(y - 7) = 2 (x - 2)\\\\y - 7 = 2x - 4\\\\y = 2x - 4 + 7 \\\\y = 2x + 3

64 teams participate in a softball tournament in which half the teams are eliminated after each round of play.
notka56 [123]

Answer:

After 6 rounds one team will win.

Step-by-step explanation:

This is an example of geometric progression,

Let p(n) represents the number of participants remaining after n rounds of play.

First term = 64

\texttt{Common ratio = }\frac{1}{2}

We have

               p(n)=a\times r^{n}\\\\p(n)=64\times \left (\frac{1}{2} \right )^{n}=2^{6}\times \left (\frac{1}{2} \right )^{n}\\\\p(n)=2^{6-n}

Number of teams remaining after n rounds of play, p(n) = 2⁶⁻ⁿ

Here we need to find for what n p(n)=1

           2^{6-n}=1\\\\2^{6-n}=2^0\\\\6-n=0\\\\n=6

After 6 rounds one team will win.

Alec is trying to find the surface area of a shoe box. What unit of measure will he use?
andrew11 [14]
The surface area is just the total of material used to make the object. So, in this case the surface area is just the material used to make the whole shoe box. 

In this question, it states that you have to find the unit of measure that Alec will use to find the surface area of the box. 
In this case, you can choose between inches, cm, ft, or many more. 
The first thing you do is find the best unit to measure the shoe box with. 

Cm would probably take to long to measure the lengths, and because 1 foot equals 12 inches, some sides of the box may not be 1 foot, so ft may be a little bit big. 
So the only unit in between cm and ft is inches. 
Inches would probably be the best unit of measure.
