Mathematics
1 answer:
Virty [35]3 years ago

Answer:

The equations 3·x - 6·y = 9 and x - 2·y = 3 are the same

The possible solution are the points (infinite) on the line of the graph representing the equation 3·x - 6·y = 9 or x - 2·y = 3 which is the same line

Step-by-step explanation:

The given linear equations are;

3·x - 6·y = 9...(1)

x - 2·y = 3...(2)

The solution of a system of two linear equations with two unknowns can be found graphically by plotting the two equations and finding the coordinates of the point of intersection of the line graphs

Making 'y' the subject of both equations gives;

For equation (1);

3·x - 6·y = 9

3·x - 9 = 6·y

y = x/2 - 3/2

For equation (2);

x - 2·y = 3

x - 3 = 2·y

y = x/2 - 3/2

We observe that the two equations are the same and will have an infinite number of solutions

The fraction computed indicates that the amount donated will be $2000000.

<h3>How to calculate the fraction</h3>

Your information is incomplete. Therefore, an overview will be given.

In this case, let's assume that the profit is 3,000,000. Therefore, the amount that is donated will be:

= 2/3 × $3000000

A bike is 110inches long a motorcycle is 40% longer . How long is the motorcycle
Dmitry_Shevchenko [17]

Answer:

The motorcycle is 154inches long.

Step-by-step explanation:

the formula = part/whole=percent/100

x/110 = 40/100

x*100=110*40

x*100=4400

<u>x*100</u>=<u>4400</u>

100       100

x=44

The bike is 110inches long and the motorcycle is 40% longer all u have to do is add what we just got which was 44 to 110= 44+110=154.

Hope that made sense :)

Which expressions are equivalent. Picture Provided. NO LINKS! NEED ANSWER ASAP
DIA [1.3K]

Answer:

B) 3^-5 <em>(1 / 243)</em> and D) 2^5 x 6^-5 <em>(</em><em>1</em><em> </em><em>/</em><em> </em><em>2</em><em>4</em><em>3</em><em>)</em>

Step-by-step explanation:

3 to the negative 5th power as a fraction is

1 / 243.

2 to the power of 5 multiplied by 6 to the power of negative 5 also equals 1 / 243.

Both expressions are equivalent to 2^5 / 6^5 because they equal the same thing (1 / 243).
