Answe its for a sophia determined that the expression    is equivalent to  –2x  –  5 by using the steps below.

 

expression:    

expression:   –2x  –  5

step 1:
choose a value of  x

choose  .

choose  .

step 2: substitute





step 3: evaluate





step 4:
compare

since  –3  =  –3, the two expressions are equivalent.

which explains whether sophia is correct?

Suppose that an airline uses a seat width of 16.516.5 in. assume men have hip breadths that are normally distributed with a mean of 14.414.4 in. and a standard deviation of 0.90.9 in. complete parts (a) through (c) below. (a) find the probability that if an individual man is randomly selected, his hip breadth will be greater than 16.516.5 in. the probability is nothing. (round to four decimal places as needed.)

James adds two numbers a + b. sally adds the same two numbers but reverse the order b + a what property of addition assures us that james and sally will get the same sum

Look at this pattern ; 1,4,9, number 10000 belongs in this pattern . what’s the place of this number?
