SOLVE THE SYSTEM OF EQUATIONS BY USING SUBSTITUTION.y = -x - 6y=x-4

1 answer:

7 0

Put X-4 to where Y is in the first equation. So;
X-4= -X-6
Then solve to find X;
Add 6 to both sides;
X+2=-X
Subtract X from both sides;
2=-X-X
2= -2X
Divide both side by -2;
-1=X

D(x)=(x^2-12x+20)/(3x)

krok68 [10]

Answers:

Vertical asymptote: x = 0

Horizontal asymptote: None

Slant asymptote: (1/3)x - 4

Explanation:

d(x) = $\frac{x^{2}-12x+20}{3x}$

= $\frac{(x-2)(x - 10)}{3x}$

Discontinuities: (terms that cancel out from numerator and denominator):

Nothing cancels so there are NO discontinuities.

Vertical asymptote (denominator cannot equal zero):

3x ≠ 0

÷3 ÷3

x ≠ 0

So asymptote is to be drawn at x = 0

Horizontal asymptote (evaluate degree of numerator and denominator):

degree of numerator (2) > degree of denominator (1)

so there is NO horizontal asymptote but slant (oblique) must be calculated.

Slant (Oblique) Asymptote (divide numerator by denominator):

(1/3)x - 4
3x) x² - 12x + 20
x²
-12x
-12x
20 (stop! because there is no "x")

So, slant asymptote is to be drawn at (1/3)x - 4

4. Caroline gets into a car accident. She is

Scrat [10]

Answer:

525,000 N

Step-by-step explanation:

Since Force is mass multiplied by acceleration, you have to create the equation 25000*21 m/s^2.

25000*21 = 525000

She hit the parked car with 525,000 Newtons of force.
