A triangle is located on a three-dimensional coordinate plane. Matrix A shows the location of each vertex, where the first colum
n represents the x coordinate, the second column represents the y coordinate, and the third column represents the z coordinate. (See image bellow)
The triangle is dilated by a scale factor of 2, then translated by the factors in matrix B, resulting in an image triangle as represented by the equation below.
(See image bellow)
In which directions are the vertices translated, as indicated by matrix B?
There are 105 in 6th grade because there are 75 boys right? So it said the ratio of girls is 7 and the ratio of boys is 5 so I divided 75 to 5 = 15 and I multiply 7 to 15 and got 105 girls.
