Hope I helped! <3
Im not sure why you said ur wrong b/c i got the same answer
f(x) = -15+ 7
f(x) = -8
Answer: These are the answers for the first section
A) 1/5(10)-4= -2
B) 1/5(-15)-4= -7
C) 1/5(2)-4= -3.6
Step-by-step explanation: You plug in those numbers for X
I think it’s 10.009 seconds. S=21.3t and s is given so you substitute it getting 213.2=21.3t so you divide by 21.3 to solve for t. You get 10.0093 so idk if you’d round it to 10.009 or 10.01
