Question 5 • Online Algebra, Function, Number A

Which values are solutions to 90 < –30p + 15? Check all that apply.p = –10p = 0p = –2.5p = 3p = –5p = 7.6

Answer
A
p = –10
B
p = 0
C
p = –2.5
D
p = 3
E
p = –5
F
p = 7.6

Explanation

Subtract 15 from both sides: 75 < −30p. Dividing by −30 reverses the inequality, giving p < −2.5. The values −10 and −5 are less than −2.5, so the correct choices are p = −10 and p = −5; p = −2.5 is not included because the inequality is strict.
