typ of math order of operatons

                                           Question # 1

Given the expression

Follow the PEMDAS order of operations

Therefore,

                                            Question # 2

Given the expression

as

     ∵

and

  ∵

Thus the equation  becomes

Therefore,

                                                       Question # 3

Given the expression

Putting a = 2, b = 4, and c = 1 in the expression

Follow the PEMDAS order of operations

Therefore,

                                                     Question # 4

Given the expression

Putting d = 2, e = 3, and f = 6 in the expression

Follow the PEMDAS order of operations

Therefore,

it's a proportional graph.

step-by-step explanation:

8 x 5 = 40         (and you have -8x and -5y)

x= absiss

y= orderly

so you have a proportional graph.

step-by-step explanation:

rectangles are made up of 4 right angles, which means that a side and a base meet perpendicular to one another.   their slopes then have to reflect perpendicular slopes.   perpendicular slopes are opposite reciprocals of one another.   for example, if the slope of one line is +2/3, then the perpendicular slope to that would be -3/2.   so we look for that combination in our choices.

all of them satisfy that condition (so what's the question, i guess? )
