68% +75 % +79 % +x ÷4≥ 80%
.68 + .75 + .79+x ÷4* 4 ≥ . 80*4
.68 + .75 + .79+x ≥ 3.2
2.22 + x ≥ 3.2
2.22 -2.22+x ≥ 3.2 -2.22
x ≥ 0.98
She has to get at least 98% to get an B.
Answer:
x = -1
Step-by-step explanation:
f(x) = (x² + 12x + 27) / (x² + 4x + 3)
f(x) = ((x + 3) (x + 9)) / ((x + 3) (x + 1))
f(x) = (x + 9) / (x + 1)
The vertical asymptote is at x = -1.

6 + 6 = 12
Since the whole line is 15 we subtract 12 from 15
15 - 12 = 3
