Answer:

To solve this problem you must follow the steps below:

1. The problem says that:

- The hot air balloon is at an altitude of 240 feet.

- It descends at 30 feet per minute.

2. Therefore, you have:

x: the time in minutes.

y: the altitute in feet.

3. Keeping all this information on mind, you can write the following equation:

y=240-30x

4. Therefore, as you can see, the answer is:

y=240-30x

Answer:

Not completely sure but I think 9

Step-by-step explanation:

In order to solve this equation, you would need to first multiply m by 2 to get 2 m. 3/2=1.5; 1.5*2 =3. 3/9 simplifies to 1/3

Then you would want to solve. So, you would need to divide 2 by 1/3 which would give you 9.

Answer:

Option D: [tex]\frac{3}{2}[/tex] is the correct answer.

Step-by-step explanation:

Given points are:

P(-8,5) and Q(-2,1)

Slope is the steepness of a straight line.

We will find slope of PQ

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\frac{1-5}{-2-(-8)\\m=\frac{-4}{-2+8}\\m=\frac{-4}{6}\\m=\frac{-2}{3}[/tex]

The product of slopes of two perpendicular lines is equal to -1.

Let,

x be the slope of other line.

m.x = -1

[tex]\frac{-2}{3}x=-1\\x=\frac{3}{2}[/tex]

Therefore,

The slope of a line perpendicular to the line PQ is [tex]\frac{3}{2}[/tex].

Hence,

Option D: [tex]\frac{3}{2}[/tex] is the correct answer.

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the first equation be A

The value of A is

2x + 3y = -2   be equation (1)

Let the second equation be B

The value of B is

3x - 6y = 18   be equation (2)

Now , on simplifying the equation , we get

Multiply equation (1) by 3 , we get

6x + 9y = -6   be equation (3)

Multiply equation (2) by 2 , we get

6x - 12y = 36   be equation (4)

Subtracting equations (3) and equation (4) , we get

21y = -42

Divide by 21 on both sides of the equation , we get

y = -2

Substitute the value of y in equation (1) , we get

2x + 3 ( -2 ) = -2

2x - 6 = -2

Adding 6 on both sides of the equation , we get

2x = 4

Divide by 2 on both sides of the equation , we get

x = 2

Therefore , the value of x and y is 2 and -2 respectively

Hence , the solutions to the equations is x = 2 and y = -2

Answer:

2 - (3x – 4) = 2x – 9​

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

2−(3x−4)=2x−9

2+−1(3x−4)=2x−9(Distribute the Negative Sign)

2+−1(3x)+(−1)(−4)=2x−9

2+−3x+4=2x−9

2+−3x+4=2x+−9

(−3x)+(2+4)=2x−9(Combine Like Terms)

−3x+6=2x−9

−3x+6=2x−9

Step 2: Subtract 2x from both sides.

−3x+6−2x=2x−9−2x

−5x+6=−9

Step 3: Subtract 6 from both sides.

−5x+6−6=−9−6

−5x=−15

Step 4: Divide both sides by -5.

Answer

The  value is  [tex]P = 131.07[/tex]

Step -by -step -explanation :

 From the question we are old that

         The sample size is  n =  20  

         The sample mean for the first person of each twin is  [tex]\= x = 100.45[/tex]

         The sample mean for the second person of each twin is  [tex]\= y = 103[/tex]

          The  correlation between both data is  r =  0.908

         The p-value is  p-value  =  0.000

          The  equation  [tex]\^ y = 13.47 + 1.12 x[/tex]

Here we are told that x represents  the first person to be given birth to among each twin  

       The value of x  considered is  x = 105

          Generally given that p-value  =  0.000

Then  the  Predicted value of  [tex]\^ y[/tex]  is mathematically represented as

           [tex]P = 13.47 + 1.12 (105)[/tex]

=>         [tex]P = 131.07[/tex]

-19561285.5554

Step-by-step explanation:

Answer:

-19561285.5554

Answer:

I don't know the options, but you would find the lowest common denominator as possible, in this case it's 40. so, you figure out how you get from the original denominator to the common one, and then do the exact same thing to the numerators.

[tex]\frac{5}{8} =\frac{25}{40}[/tex] and [tex]\frac{3}{10} = \frac{12}{40}[/tex]

and then take the two new fractions and subtract the numerators to get what the answer is:

[tex]\frac{25}{40} - \frac{12}{40} = \frac{13}{40}[/tex]= 0.325

normally you would simplify, but this fraction is already in it's simplest form. so you could convert to a decimal, but only if the directions say to.

Answer:

A translation 9 units right

Step-by-step explanation:

Given

[tex]f(x) = 4x + 2[/tex]

[tex]g(x) = 4(x -9)+ 2[/tex]

Required

Translation of f(x) to g(x)

To do this, we take the options one after the other.

A translation 9 units right

When an original function f(x) is translated to the right by h points, the resulting function g(x) is

[tex]g(x) = f(x - h)[/tex]

So, we have that:

[tex]f(x) = 4x + 2[/tex]

When translated to the right by 9 points,

[tex]g(x) = 4(x - 9) + 2[/tex]

Hence, option A answers the question

Answer:

(x+2) (x+2)

Step-by-step explanation:

x2+ (2+2)x + 4

x2 + 2x + 2x + 4

x(x+2) + 2(x + 2)

(x+2) (x+2)

Answer:

a) [tex]f(x) = \frac{1}{3} \sqrt{x+4}[/tex]

b) [tex]f(x)=4\sqrt{x} + 3[/tex]

c) [tex]f(x) = 2\sqrt{x} -6[/tex]

Step-by-step explanation:

a) The function will be;

⇒ f (x) = 1/3 √(x + 4)

b) The function will be;

⇒ f (x) = 4√x + 3

c) The function will be;

⇒ f (x) = 2√x - 6

What is Translation?

A transformation that occurs when a figure is moved from one location to another location without changing its size or shape is called translation.

Given that;

There are some transformations are given.

Now,

For (a);

The function is horizontally shifting the graph 4 units to the left of

f(x) = √x.

So, The function become;

f (x) = √(x + 4)

And, Then vertically compression by a factor of 1/3.

So, The function become;

f (x) = 1/3 √(x + 4)

For b:

The function is vertically stretching the graph by a factor of 4 of f(x) = √x.

So, The function become;

f (x) = √x + 3

And, Then vertically shifting the graph 3 units up.

So, The function will be;

⇒ f (x) = 4√x + 3

For c;

The function is horizontally stretching the graph of f(x) = √x by a factor of 2.

So, The function become;

f (x) = 2√x

And, Then vertically shifting the graph 6 units down.

So, The function will be;

⇒ f (x) = 2√x - 6

Thus,

a) The function will be;

⇒ f (x) = 1/3 √(x + 4)

b) The function will be;

⇒ f (x) = 4√x + 3

c) The function will be;

⇒ f (x) = 2√x - 6
