After simplifying, which expressions are equivalent? check all that apply.

(3.4a – 1.7b) + (2.5a – 3.9b)

(2.5a + 1.6b) + (3.4a + 4b)

(–3.9b + a) + (–1.7b + 4.9a)

–0.4b + (6b – 5.9a)

5.9a – 5.6b

Expression 1, 3 and 5 are equivalent.

Step-by-step explanation:

After simplifying each expression we get,

1.

Combine like term.

Similarly,

2.

3.

4.

5.

Therefore expression 1, 3 and 5 are equivalent.

x intercept = (-1,0)   (4,0)
