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 d

ecided 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.

Question 4(Multiple Choice Worth 2 points)
Mnenie [13.5K]

The transformation needed to form g(x) = 3(x + 2)^2-1 is a vertical translation of the function down by 1 unit, horizontal shift to the right by 2 units and a vertical stretch by 3 units

<h3>Transformation of functions</h3>

Transformation is the technique used to change the position of a figure on an xy-plane.

Given the parent function f(x) = x², the transformation needed to form g(x) = 3(x + 2)^2-1 is a vertical translation of the function down by 1 unit, horizontal shift to the right by 2 units and a vertical stretch by 3 units

Triangle ABC is transformed to triangle A′B′C′, as shown below:
Montano1993 [528]

Answer:

C. m<CAB = m<C'A'B'

Step-by-step explanation:

Triangle ABC looks like it was only reflected over the line y = 0. If the triangle was only reflected then the triangles should be congruent to each other.

What is the highest common factor of 12 and 16?​
guajiro [1.7K]

Answer:

4

Step-by-step explanation:

1) to find hcf, first look at what both 12 and 16 are divisible by

12 and 16 are divisible by 2

so

12/2=6

16/2=8

now we have 6,8

6 and 8 are divisible by 2 as well

6/2=3

8/2=4

3,4 is what we are left with

since we had to divide these numbers by 2 both times, multiply them.

2*2=4

4 is the hcf
