-9/7 is the inverse of 9/7.

-9/-7 = 9/7

9/7 + (-9/7) = 0

-9/7 is consequently the additive opposite of -9/-7.

By merely switching the integer's sign, you can add the original number and the additive inverse to produce a result equal to 0. The value that, when added to the original number, results in zero is known as a number's additive inverse. It is what we add to a number to make it equal to zero. Considering that an is the starting number, its additive inverse will be a minus one, or -a, such that;

a+(-a) = a – a = 0

Given :

Mr. Ford's 2002 Focus would get 36 miles/gallon.

He starts with 13.2 gallons of gas in his gas tank.

To Find :

Write a slope-intercept equation that models how much gas remains in his tank after each mile of of travel(hint: g/mi).

Solution :

Let, required equation is :

y = mx + c

Here, y is gas remains in gallons.

Here, m is slope i.e. miles travelled per gallon.

So, m = -36  ( since gas is decreasing )

Initially distance travelled is 0 i.e. putting x = 0

y = c = 13.2

Therefore, y = -36x + 13.2 this is the required equation.

The number is 35.

What is an equation?

An equation is a statement of equality between two expressions. It uses the equal sign (=) to show that the expressions on either side of the sign have the same value.

For example 2x+3=5y-7z, and x+y=5 are examples of equations.

In solving your problem,

25 less than the sum of a number and 5 results in 15, can be written as an equation like this:

let x be the number we want to find.

x + 5 =15+25 (25 less than the sum of x+5)

x + 5 = 40

then

x=40-5

x=35

So the number is 35.

Answer:

The box must be 2.4 in deep.

Step-by-step explanation:

Front dimensions are 9 in by 7.5 in.  Find the area of the front:  it is

A = (9 in)(7.5 in) = 67.5 in^2.  One way to complete this work would be to divide the given volume by this area, 67.5 in^2.  

A slightly different approach follows:

The volume must be 162 in^2.  Given V = (width)(height)(depth),

                                   V

(depth) must be -----------------------

                            (width)(height)

In this particular case,

                                162 in^3

(depth) must be ----------------------- = 2.4 in

                              (7.5 in)(9 in)

The box must be 2.4 in deep.

Step-by-step explanation:

Answer:

y=−26.7x+14.1

Step-by-step explanation:

y=−17.5x+2.7x+14.1−11.9x

y=−26.7x+14.1

Solve for x:

Step 1: Flip the equation.

−26.7x+14.1=y

Step 2: Add -14.1 to both sides.

−26.7x+14.1+−14.1=y+−14.1

−26.7x=y−14.1

P (x>5) = 0.5324014=0.523

Step-by-step explanation:

Here success = p= 0.7 and failure = q= 1-p= 1-0.7 = 0.3

Number of surgeries= n= 8

Applying the binomial distribution

( p+q) ^n= nC x p^x . q^n-x

More than 5 means  6,7, and 8

( p+q) ^8= 8C 5 (0.7)^5 . (0.3)^3

                =56* 0.16807*0.027

                       = 0.254121

( p+q) ^8= 8C 6 (0.7)^6 . (0.3)^2

                =  28* 0.1177* 0.09

                    = 0.296604

( p+q) ^8= 8C 7 (0.7)^7 . (0.3)^1

                =  8* 0.0824* 0.3

                  = 0.19776

( p+q) ^8= 8C8 (0.7)^8 . (0.3)^0

                =  1* 0.05765* 1

                  =0.05765

Adding the above all probabilities  gives

P (x>5) = P (x=6) + P(x=7) + P(x=8)

               = 0.296604+0.19776+0.05765

                   = 0.5324014

343200 fts distance travelled in an hour

5720 ft was travelled in 1 minute and,

95.33 ft distance was travelled in 1 second.

The mile is a customary unit of measurement in the United States and the United Kingdom that is based on the older English unit of length equal to 5,280 English feet, or 1,760 yards. It is often referred to as the international mile or statute mile to distinguish it from other miles.

The British imperial and American customary systems of measurement both use the foot as a unit of length, denoted by the standard symbol: ft. An other sign that is frequently used is the prime symbol, ′. One foot is precisely equal to 0.3048 meters as of the International Yard and Pound Agreement of 1959.

5,280 feet per mile, sometimes known as a statute mile, is a unit of measurement (1.609 km). It derives from the mille passus, or "thousand paces," of the Romans, which was equivalent to 5,000 Roman feet.

65 miles per hour

so 65 * 5280 = 343200 ft travelled in 1 hr

in one minute distance travelled = 343200/60 = 5720  fts

and in one second distance travelled = 5720/60 = 95.33 fts.

y = 2x + 1 -------- (I)

y = 4x + 6 --------(ii)

from eqn (I)

y = 2x + 1

sub y = 2x + 1 in eqn (ii)

2x + 1 = 4x + 6

2x - 4x = 6 - 1

-2x = 5

x = -5/2

Therefore a quadratic function can be written in vertex form as

y = a(x - h)^2 + k.

In mathematics, a polynomial of degree two in one or more variables is referred to as a quadratic polynomial. The polynomial function that a quadratic polynomial defines is known as a quadratic function.

In an equation such as the quadratic equation, cubic equation, etc., a polynomial function is a function that only uses non-negative integer powers or only positive integer exponents of a variable. For instance, the polynomial 2x+5 has an exponent of 1.

A quadratic function can be written in vertex form as y = a(x - h)^2 + k

Where (h, k) is the vertex, and a is the leading coefficient.

y = ax^2 + bx + c (standard form)

y = a(x + b/2a)^2 + c - b^2/4a

y = a(x - h)^2 + k where h = -b/2a and k = c - b^2/4a

For example,when y = 3x^2 - 6x - 5

y = 3x^2 - 6x - 5

y = 3(x^2 - 2x) - 5

y = 3(x^2 - 2x + 1 - 1) - 5 = 3(x - 1)^2 - 8

So, the equation is in vertex form y = 3(x - 1)^2 - 8

Note that this only works for parabolas that opens upwards or downwards, if the parabola opens to the sides, the vertex form is y = a(x-h)^2 +k

After a work out, the simplest form of e:g is 3:10.

Ratio is an expression which shows the relationship between two numbers or variables. It can generally be expressed in two forms, viz; a:b or a/ b.

To work out the simplest form of e:g as required in the question,

e/ f = 2/ 5

2f = 5e ........... 1

f/g = 3/ 4

3g = 4f ........... 2

From equation 1,

Answer:

The formula is [tex]a_n = 3n-2[/tex]

The 14th term is 40, in other words, [tex]a_{14} = 40[/tex]

========================================================

Explanation:

The given sequence is 1, 4, 7, 10, ...

Subtract each adjacent term:

This shows that each term is increasing by 3. This is the common difference, so d = 3.

The first term is [tex]a_1 = 1[/tex]

The nth term of the arithmetic sequence is...

[tex]a_n = a_1 + d(n-1)\\\\a_n = 1 + 3(n-1)\\\\a_n = 1 + 3n-3\\\\a_n = 3n-2\\\\[/tex]

As a check, let's plug in say n = 3 to find that:

[tex]a_n = 3n-2\\\\a_3 = 3(3)-2\\\\a_3 = 9-2\\\\a_3 = 7\\\\[/tex]

The third term is 7, which matches with the sequence given to us. I'll let you confirm the other values.

-----------

We'll repeat this idea but now for n = 14 to find the 14th term of the sequence.

[tex]a_n = 3n-2\\\\a_{14} = 3(14)-2\\\\a_{14} = 42-2\\\\a_{14} = 40\\\\[/tex]

The 14th term is 40.

You can make a table of values to help confirm the answer. In the first column you'll have the values of n (1,2,3,...) all the way up to 14. The second column will consist of the sequence 1, 4, 7, 10, ... each time going up by 3 until you reach the 14th term of 40.

Answer:

Step-by-step explanation:

1. What are the x-intercepts of the graph representing f?  They are the points on the horizontal axis where the graph touches or crosses the axis.  Note that on this axis, y = 0.

2. What are the x- and y-coordinates of the vertex of the graph?  Since the function is written as the product of two binomials, we can take these coordinates directly from the binomials:  (x - 2) yields x = 2 and (x + 4) yields x = -4.

3. What is the y-intercept?   Multiply out these binomials.  We get:

f(x) = x^2 + 2 - 8.   When x = 0, y = -8.  The y-intercept is (0, -8).

1) The x-intercepts of the graph representing f are; 2 and 4

2) The x- and y-coordinates of the vertex of the graph are; (1, -5)

3) The y-intercept is at; (0, -8)

We are given the function; f(x) = (x - 2)(x + 4)

1) The x-intercepts of a graph are the points where the graph crosses the x-axis. The x-intercepts are the value of x when f(x) = 0. Thus, the x-intercepts here are 2 and 4.

2) The vertex is the lowest point of the graph in this case as the parabola opens upwards.

Let us expand the function to get;

f(x) = x² - 2x + 4x - 8

f(x) = x² + 2x - 8

where;  a = 1, b = 2, c = -8

Formula for the x-coordinate of the vertex is;

x = -b/2a

x = -2/2(1)

x = 1

Thus;

y =  (1 - 2)(1 + 4)

y = -5

x- and y-coordinates of the vertex of the graph are; (1, -5)

3) The y-intercept is the point at which x = 0. Thus;

y = 0² + 2(0) - 8

y = -8

The y-intercept is (0, -8).
