Triangle ABC and DEF are shown on the graph. Move options to the blanks to show that ABC = DEF using transformations, given the corresponding angles and sides are congruent.

its 4 because 2 times 2 is 4, if you double the number two you get four

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
