The triangles are congruent by the SSS congruence theorem. Which ridges transformation(s) can map ABC onto FED?

5× 1/2 = ? a) more than 5 because you are multiplying by a whole number b) 5/10 because you multiply the numerator and denominator by 5 c) less than 5 because you are multiplying by a number that is more than 1 d) less than 5 because you are multiplying by a number that is less than 1

Y=21.95x+10 y=22.45x solve by substitution
