Solution:

[tex]\frac{\left(y-1\right)^2}{9}-\frac{\left(x+4\right)^2}{4}=1[/tex]

Step-by-step explanation:

We have the general equation for our up - down facing hyperbola as (y - k)² / b²- (x - h)² / a²  = 1. Let's start listing the properties of this graph -

• Taking a look at the graph we see that the center point of our hyperbola here is (- 4, 1). Therefore (h, k) = (- 4,1).

• Another thing here is our key value a. This is the semi distance from the center to one of the vertices. Here it will be the distance from points (- 4,1) and (- 4,4) or 3 unit difference. Therefore a = 3.

• That leaves us with our asymptotes. Now remember that it will be in the form y = ± b / a. We already know a = 3, so we have to find b. Looking at this graph I can say that another point besides (- 4,1) that lies on the " dotted line " is (- 2, - 2). Calculating the slope of the dotted line would be as follows,

Given: (- 4,1) and (- 2, - 2)

Slope = - 2 + 4 / - 2 - 1 = 2 / 3

We have the equation y = 2 / 3x. Therefore b = 2. Let's substitute to receive our equation...

h = - 4, k = 1, b = 2, a = 3

(y - 1)² / (3)²- (x + 4)² / (2)²  = 1

(y - 1)² / 9 - (x + 4)² / 4  = 1 ~ your solution is the last one, option d

Answer:

[tex]= \frac{2m^2n^8}{3}[/tex]

Step-by-step explanation:

Given expression is

[tex](\frac{4m^{-2}n^8}{9m^{-6}n^{-8}} )^{\frac{1}{2}[/tex]

The correct simplified form is shown below:-

From the above equation, we will simplify

we will shift [tex]m^{-6}[/tex] to the numerator and we will use the negative exponent rule, that is

[tex]= (\frac{4m^{-2}n^8m^6}{9n^{-8}} )^{\frac{1}{2}[/tex]

now we will shift the [tex]n^{-8}[/tex] to the numerator and we will use the negative exponent rule, that is

[tex]= (\frac{4m^{-2}n^8m^6n^8}{9} )^{\frac{1}{2}[/tex]

here we will solve the above equation which is shown below

[tex]= (\frac{4m^4n^{16}}{9}) ^\frac{1}{2}[/tex]

So,

[tex]= (\frac{(2)^2(m^2)^2(n^8)^2}{(3)^2} ^\frac{1}{2}[/tex]

Which gives result

[tex]= \frac{2m^2n^8}{3}[/tex]

Answer:

A) exactly one solution-(-1/6,0)

Step-by-step explanation:

6x-y=-1

6x+y=-1

First, use elimination and cancel out the y-values:

you would get: 12x=-2

Divide both sides by 12: (12x/12)=(-2/12)--x=-1/6

x=-1/6

Now, subtitute the x-value into tje first equation to find the y-value:

6(-1/6)-y=-1

-1-y=-1

-1+1-y=-1+1

-y=0

-y/-1=0/-1

y=0

y=0

Answer:

1

a) It is possible and it is the only proper value of angle 2

b) Explanation Below

Angle 1 adds to the two other internal angles to get 180

(angle1) + 30 + 42 = 180

angle1 + 72 = 180

angle1 = 180-72

angle1 = 108 degrees

Subtract this from 180 to find the measure of angle 2

angle2 = 180 - angle1

angle2 = 180-108

angle2 = 72

A shortcut is to use the remote interior angle theorem to add up the interior angles 30 and 42 to get 72 as our exterior angle that is not adjacent to any of the interior angles we just added. Hence the "remote" portion.

Answer:

x = 22.5

Step-by-step explanation:

The tangent- secant angle x is half the difference of the measures of the intercepted arcs, that is

[tex]\frac{1}{2}[/tex] (4x + 5 - 50 ) = x ( multiply both sides by 2 )

4x - 45 = 2x ( subtract 2x from both sides )

2x - 45 = 0 ( add 45 to both sides )

2x = 45 ( divide both sides by 2 )

x = 22.5

Answer:

B.99 its the answer....

Answer:

Step-by-step explanation:

Bob: 8x

Josh: 4x

Ralph: x

8x + x = 180

9x = 180

X= 20

Josh:

X = 20

Multiply it by 4

X =80

Josh spent $80

The amount of money spent by Bob, Josh, and Ralph will be $160, $80, and $20.

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

During a vacation together, Bob spent twice as much as Josh, who spent four times as much as Ralph.

Let x be the amount of money spent by Ralph.

Then Bob spent 8x and Josh spent 4x.

If Bob and Ralph together spent $180. Then the equation will be

8x + x = 180

     9x = 180

       x = 180 / 9

       x = $20

Then the money spent by Bob and Josh will be

Bob = 8x = 8 × 20 = $160

Josh = 4x = 4 × 20 = $80

Then the amount of money spent by Bob, Josh, and Ralph will be $160, $80, and $20.

Five and twenty-two hundredths centimeters as a decimal will be 5.22.

A decimal is a number that is divided into two parts: a whole and a fraction. Between integers, decimal numbers are used to express the numerical value of complete and partially whole amounts.

Given, we need to find out the five and twenty-two hundredths centimeters as a decimal. Since five is a whole number so it will be 5 and twenty-two hundredths will be 0.22.

Answer:

5

Step-by-step explanation:

The degree of a polynomial simply means what the highest power of an variable is. In this case we see that y⁵ < y³ < y², so 5 would be our highest exponent and answer.

Answer:

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{5}}}}}[/tex]

Step-by-step explanation:

In the polynomial with one variable , highest power ( exponent ) is the degree of the polynomial.

In polynomial [tex] \sf{4 {y}^{3} + 3 {y}^{2} - {y}^{5} }[/tex]

The power of 4y in the first term = 3

The power of 3y in the second term = 2

The power of y in the third term = 5

Since, the highest power is 5 , the degree of the polynomial is 5 .

Step-by-step explanation:

Hey, there!!

To graph a equation, we must find the coordinates of x and y.

So, as the equation is,

[tex]y = \frac{6}{5} x + 1[/tex]

Here, the equation is for finding the coordinates of y and x should be supposed. Remember, always suppose the value in equal interval.

Now,

x = 0 1 2 3

y= 1 2.2 3.4 4.6

Here, if you are confused how do i get 1, 2.2,3.4,4.6 as y value, put the value of x such as,

[tex]y = \frac{6}{5} \times 0 + 1[/tex]

which is equal to 1.

so,in this we got values.

Now,

List coordinates,

Answer:

We have the function y = k(x).

We want to define a new function p(x), such that is equal to k(x) but translated down 3 units.

When we have a general case of a function y = f(x), the function g(x) = f(x) + A is a translation of A units up (if A is positive) or A units down (if A is negative).

Then if we want to go 3 units up, we should have:

p(x) = k(x) + 3.

So now our points are:

(x, y) = (x, p(x)) = (x, k(x) + 3)

So for all the points the y-coordinate has ben mooved 3 units up.

Answer:

m∠AED = 130°

Step-by-step explanation:

Definition of Supplementary Angles: 2 angles adjacent to each other that add up to 180°

Step 1: Define variables

m∠AEC = 50°

m∠AED = x (unknown)

Step 2: Set up equation

50 + x = 180

Step 3: Solve for x (subtract 50 on both sides)

x = 130°

Step 4: Replace variable x

m∠AED = 130°

Answer:130°

Step-by-step explanation: 50° is on a straight line. Therefore 180-50=130
