Answer:
x=20
Step-by-step explanation:
form a ratio
28:7
4:1
x:5
x=20
Answer:
12
Step-by-step explanation:
3 x 4 = 12
The correct answer would be B because 88 divided by 11 would be 8 and therfore it would justift that the ration would be equal to 88:33
1) function f(x)
x - 5
f(x) = ----------------
3x^2 - 17x - 28
2) factor the denominator:
3x^2 - 17x - 28 = (3x + 4)(x - 7)
x - 5
=> f(x) = -----------------------
(3x + 4) (x - 7)
3) Find the limits when x → - 4/3 and when x → 7
Lim of f(x) when x → - 4/3 = +/- ∞
=> vertical assymptote x = - 4/3
Lim of f(x) when x → 7 = +/- ∞
=> vertical assymptote x = 7
Answer: there are assympotes at x = 7 and x = - 4/3
