Subtract 6 from both sides

-3x = -9 - 6

Simplify -9 - 6 to -15

-3x = -15

Divide both sides by -3

x = -15/-3

Two negatives make a positive

x = 15/3

Simplify 15/3 to 5

<u>x = 5</u>

What is the positive slope of the asymptote of (y+11)^2/100-(x-6)^2/4=1? The positive slope of the asymptote is .
VladimirAG [237]

Answer:

the  positive slope of the asymptote = 5

Step-by-step explanation:

Given that:

\frac{(y+11)^2}{100} -\frac{(x-6)^2}{4} =1

Using the standard form of the equation:

\frac{(y-k)^2}{a^2}-\frac{(x-h)^2}{b^2}= 1

where:

(h,k) are the center of the hyperbola.

and the y term is in front of the x term  indicating that the  hyperbola opens up and down.

a = distance that indicates  how far above and below of the center the vertices of the hyperbola are.

For the above standard equation; the equation for the asymptote is:

y = \pm \frac{a}{b} (x-h)+k

where;

\frac{a}{b} is the slope

From above;

(h,k) = 11, 100

a^2 = 100

a = \sqrt{100}

a = 10

b^2 =4

b = \sqrt{4}

b = 2

y = \pm \frac{10}{2} (x-11)+2

y = \pm 5 (x-11)+2

y = 5x-53 , -5x -57

Since we are to find the positive slope of the asymptote: we have  

\frac{a}{b} to be  the slope in the equation  y = \pm \frac{10}{2} (y-11)+2

\frac{a}{b}  = \frac{10}{2}

\frac{a}{b}  = 5

Thus, the  positive slope of the asymptote = 5

The sum of two numbers is 39.Three times the smaller number exceeds the larger number by 81. Find the numbers
Mice21 [21]

Let smaller no be x and bigger be y

  • x+y=39--(1)
  • 3x=y+81
  • y=3x-81
  • y=3(x-27)--(2)

Put it in eq(1)

  • x+3(x-27)=39
  • x+3x-81=39
  • 4x=81+39
  • 4x=120
  • x=30

Now

  • x+y=39
  • y=39-30
  • y=9

The numbers are 9 and 30

dolphi86 [110]

Answer:

30

Step-by-step explanation:

6 papers per hour • 5 hours of work = 30 papers done in 5 hours.

If I need to go further, it would take 11 hours to grade all the papers because 6 • 11 = 66.
