If z(t) = 2t2 + 7t – 4, find z(–2) and z(7). a. z(–2) = 11; z(7) = 101 b. z(–2) = –26; z(7) = 143 c. z(–2) = –2; z(7) = 241 d. z(–2) = –10; z(7) = 143

i can you with this question sweetie!

step-by-step explanation:

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice
