Check all of the expressions that are equal to the one below.
(9) • (-3+8)

(9) • (-3+8)

We know that (-3 + 8) • (9) is equal to the expression above because of commutative property.

If we apply the -1 on "-(3-8) • (9)" we get (-3+8)x(9) which looks exactly like the first answer choice.

Assuming that I'm reading the third answer correctly, it is not equivalent because the 9 has to be applied to the -3 and the 8 for distributive property to work.

The last answer choice is an example of distributive property and is equivalent.

answers: A,B,D

connie < felicia < stew

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4
