True or False: A linear graph can have a maximum or a minimum
False
Write a verbal expression for 4r + 9.
Four times r plus nine
a/2 + 9 = 30
a = 42
Find the solution set for 3b - 4 = 8
b = 4
5(c + 3) = 15 + 2(2c - 1)
c = -2
m - 5 = -23
m = -18
Translate m2 - 2r + 1 into a sentance
m squared minus four equals two times r plus one
10(a + 1) - 14a = 9 - (4a - 1)
