Answer:
b and c
Step-by-step explanation:
The excluded values are any values of x that make the denominator equal to zero as this would make the rational function undefined.
Equate the denominator to zero and solve for x to obtain excluded values
1
solve 1 - 2x = 0 ⇒ 2x = 1 ⇒ x = → b
2
x² - 2x - 15 = 0 ← in standard form
(x - 5)(x + 3) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 5 = 0 ⇒ x = 5
x + 3 = 0 ⇒ x = - 3
Excluded values are x = - 3 and x = 5 → c

I got it right so this should help
if you want the explanation i can give that to u just comment
Graph the inequality by finding the boundary line, then shading the appropriate area.
Answer: y < -4 + 3x
Okay so basically, i’m pretty sure you have to make them catch up with each other, if i’m correct), so if it’s 30 to each student plus 2500 then 2 students is 60 bucks, 3 students is 90 and so on so forth......then if 1 student - 60 then 2 is 120 and vice versa ya know. So keep adding on the amount due for each student plus the extra amount which doesn’t change and make them catch up with each other. Keep on adding student after student and adding the fee until they match up. Sorry it’s not the exact answer but i hope this explains it... if i’m right
