1. identify the matrix transformation of δxyz, which has coordinates x(−2, −2),y(4, 1), and z(0, 6), for a dilation by a factor of 2.5. then identify the correct vertices of the image 2. identify the matrix transformation of δfgh, which has coordinates f(0, −1),g(5, −1), and h(4, 3), for a dilation by a factor of 1/4. then identify the correct vertices of the image

If dilation is about the origin, and there is no translation, rotation, or reflection involved, the matrix of image coordinates is the matrix of original coordinates multiplied by the scalar dilation factor.

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.

but which class are u may know that first
