Which equations are equivalent to 1 + 2|2 - x[= 4 ? Check all that apply. - 5 미 2 - 1 미 13 12 - x1 = 15 12 -x=_1 15 12 -x]=_4 Intro​

the image of (6, 9) under a dilation is (4, 6). the scale factor is

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
