Which system of equations has exactly one solution? 2 x minus 4 y = 8. x + y = 7.
3 x + y = negative 1. 6 x + 2 y = negative 2.
3 x + 3 y = 3. Negative 6 x minus 6 y = 3.
3 x minus 2 y = 4. Negative 3 x + 2 y = 4.

25/4

step-by-step explanation:

call segment cd's length x. because dc and ab are parallel, angle acd and cab, so triangles adc and abc are similar and we can set up the equation x / ac = ac / ab, or x / 5 = 5 / 4 and x = 25/4.

answer: true
