If m = 5 and n = -2, evaluate 3m - 4n and n^2 - m and find the product of the two expressions.

[ 3(5) - 4(-2)] * [ (-2)^2 - 5 ] =

[15 + 8 ] * [ 4 - 5 ] =

[23] * [ -1] =

-23

Which statement MUST be true given that a, b, c, and d are all integers, and a < 0 < b < c < d?

1/a > b 1/a is negatve b is positive so..... false

b - a > c - a add a to both sides b > c so...... false

-a > c not necessarily true ....if a = -1 and c = 5.......this is false

a > - d if a = -1 and d = 1/2 then -1 > -1/2 ??? false

c + a < d + a subtract a from both sides c < d which is true

Least to greatest

-3.75 -3.68 - 3.65 -3.60
