To solve the system of linear equations 3 x minus 2 y = 4 and 9 x minus 6 y = 12 by using the linear combination method, Henry decided that he should first multiply the first equation by –3 and then add the two equations together to eliminate the x-terms. When he did so, he also eliminated the y-terms and got the equation 0 = 0, so he thought that the system of equations must have an infinite number of solutions. To check his answer, he graphed the equations 3 x minus 2 y = 4 and 9 x minus 6 y = 12 with his graphing calculator, but he could only see one line. Why is this? because the system of equations actually has only one solution because the system of equations actually has no solution because the graphs of the two equations overlap each other because the graph of one of the equations does not existTo solve the system of linear equations 3 x minus 2 y = 4 and 9 x minus 6 y = 12 by using the linear combination method, Henry decided that he should first multiply the first equation by –3 and then add the two equations together to eliminate the x-terms.

After the point B(2, 3) is translated along the vector <5, 7> the image will be located at ?

Answers

Answer:

(7, 10)

Step-by-step explanation:

The vector has an x component of 5 and a y component of 7, so we can add each of these components to the coordinates of B to get its image:

B(2,3)

B'(2 + 5, 3 + 7) = B'(7, 10)

The image will be located at (7, 10).

What is vector?

Vectors, in Maths, exist as objects which have both, magnitude and direction. Magnitude determines the size of the vector. It exists described by a line with an arrow, where the length of the line exists the magnitude of the vector and the arrow displays the direction.

The vector has an x component of 5 and a y component of 7, so we can add each of these components to the coordinates of B to get its image:

B(2,3)

B'(2 + 5, 3 + 7) = B'(7, 10)

please explain how to do this system of equations 2y=6x+10 y=2x+4

Answers

Answer:

x=-1, y=2

Step-by-step explanation:

Given:

2y=6x+10

y=2x+4

Substitution for y into first equation:

2(2x+4)=6x+10

4x+8=6x+10

0=2x+2

2x=-2

x=-1

y=2(-1)+4

Step-by-step explanation:

The laws of exponents state that when multiplying exponents of the same base, you can add the exponents. Therefore, [tex]a^{3}*a^{6}=a^{3+6}[/tex], or [tex]a^{9}[/tex]. Same with the b's. [tex]b^{2}*b^{5}=b^{7}[/tex]. Multiplying 4*3 is easy; 12. Multiply all together and you get [tex]12a^{9}b^{7}[/tex].

Translate and solve: 662% of what number is 3641?​

Answers

Answer:

550

Step-by-step explanation:

To find the percent of a number, we multiply the number by the decimal form of the percent. The decimal form of a percent can be found by moving the decimal point two places to the left.

Example: 45% = 0.45

In this case, we need to work backward. So, instead of multiplying, we will divide to undo the multiplication.

662% = 6.62

We need to divide 3641 by 6.62 to get the number that 3641 is 662% of. This number will be a smaller number since 662% of a number will be larger than the original number, This is because it is greater than 100%, which would be the number.

Example 100% of 6 is 6 since 6 x 1.00 is 6.

3641/6.62 = 550

However, we can also verify this by multiplying 550 by 6.62 to find 662% of 550.

6.62 x 550 = 3641
