Mathematics
1 answer:
kaheart [24]3 years ago
7 0
1. x1/2=\frac{-3\pm \sqrt{9+40} }{2}
VA(the vertical asymptotes): x=-5,  x=2
2. x1/2=\frac{9\pm \sqrt{81-72} }{2}
VA: x=3, x=6
3.  \lim_{n \to \infty}  \frac{4x}{7}=∞
There is no HA.
4. \lim_{n \to \infty} \frac{7x+1}{2x-9}= \frac{7}{9}
HA : y=7/2
5. \lim_{n \to \infty}  \frac{ x^{2} +5x+3}{4x-1} =∞
There is no HA.
6. m=\lim_{n \to \infty}  \frac{ x^{2} -4x+8}{ x^{2} +2x}
m = 1
b=\lim_{n \to \infty}  \frac{ x^{2} -4x+8- x^{2} -2x}{x+2}
b = -6
OA: y = x - 6
7. Same method:
m = 2
b = 0
OA: y = 2x
8. m = 0
There is no OA.
m = 4 
b=-1
OA: y=4x-1

X + 7y = 21<br> x + 4y = 15<br> Solve the simultaneous equations
Mariulka [41]

<u>Answer</u>:

x = 7, y = 2

<u>Explanation</u>:

equations given:

x + 7y = 21

x + 4y = 15

make "x" the subject:

x + 7y = 21

x = 21 - 7y .........equation 1

x + 4y = 15

x = 15 - 4y .......equation 2

Solving both the equations simultaneously:

15 - 4y = 21 - 7y

-4y + 7y = 21 - 15

3y = 6

y = 6 ÷ 3

y = 2

If y is 2

Then x = 21 -7y;

x = 21 - 7(2)

x = 21 - 14

x = 7
