n(x) will give output for any number except 0.

An equation consists of two sides, the left-hand side and the right-hand side, which are separated by an equals sign (=). The left-hand side and the right-hand side each contain one or more variables, which are quantities that can vary or be assigned different values.

Given

n(x)=2/x

From the given option, 3 and5  will satisfy the equation.

n(x)=2/3 for the value of x=3

n(x)=2/5 for the value of  x=5

Answer: It is b

Step-by-step explanation: hope this helps :)

Answer:

x = 8

y = 21

Step-by-step explanation:

y = 4x − 11

x + y = 29

Solve for x:

x + y = 29

x + 4x − 11 = 29

5x − 11 = 29

5x = 40

x = 8

Solve for y:

y = 4x − 11

y = 4 × 8 − 11

y = 21

The number of boxes of crackers left with Eloise is 1 5/6 boxes of crackers

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 number of boxes of crackers left with Eloise be = A

Now , the total number of boxes of crackers be = 3 boxes

The number of boxes of crackers ate on Saturday = 1/2

The number of boxes of crackers ate on Sunday = 2/3

So , the equation will be

Number of boxes of crackers left with Eloise A =  total number of boxes of crackers - number of boxes of crackers ate on Saturday - number of boxes of crackers ate on Sunday

Substituting the values in the equation , we get

Number of boxes of crackers left with Eloise A = 3 - 1/2 - 1/3

On simplifying the equation , we get

Number of boxes of crackers left with Eloise A = 5/2 - 2/3

Number of boxes of crackers left with Eloise A = ( 15 - 4 ) / 6

Number of boxes of crackers left with Eloise A = 11/6

Number of boxes of crackers left with Eloise A = 1 5/6 boxes

Therefore , the value of A is 1 5/6 boxes

Hence , the number of boxes left is 1 5/6 boxes of crackers

Answer:

40 + 4√13

Step-by-step explanation:

A kite is a quadrilateral (has four sides) with two pairs of equal adjacent sides. The longer diagonal of a kite bisects the shorter diagonal.

Since in kite JKLM, diagonal KM bisects JL, hence KM is the longer diagonal.

JP = LP

JL = 12

JL = JP + LP

12 = JP + LP

2JP = 12 (LP = JP)

JP = 6

We can find JK using Pythagoras theorem, hence:

JK² = JP² + KP²

JK² = 4² + 6²

JK² = 16 + 36

JK² = 52

JK = √52 = 2√13

JK = KL = 2√13

ML = JM = 20

Perimeter of kite = JK + KL + ML + JM = 20 + 20 + 2√13 + 2√13

Perimeter of kite = 40 + 4√13

Answer:

See explanation

Step-by-step explanation:

The question is incomplete. However, I'll ask and answer possible questions that emanate from the given parameter.

A possible question is: Write the given information as a function of distance.

We have that;

[tex]Base\ Distance = 200[/tex]

[tex]Time = t[/tex]

[tex]Rate = r[/tex]

The function would be calculated as:

Base Distance + Rate * Time

Substitute values for Base Distance, Rate and Time

This gives:

[tex]200 + r * t[/tex]

[tex]200 + rt[/tex]

Hence;

[tex]Distance = 200 + rt[/tex]

Another possible question is to determine the current distance travelled by the family at a rate of 80 miles per hour for 3 hours.

Here, we have:

[tex]r = 80[/tex]

[tex]t = 3[/tex]

Substitute these values in [tex]Function = 200 + rt[/tex]

[tex]Distance = 200 + 80 * 3[/tex]

[tex]Distance = 200 + 240[/tex]

[tex]Distance = 440[/tex]

Answer:

Answer: C

Step-by-step explanation: If a car is 12 inches a room could possibly be 16 feet and a room and a car might or if not might have the same width

I hoped i helped :)

Answer:   C) 16 feet

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

Work Shown:

3 inches on paper = 4 feet in real life

Multiply both sides by 4 so that the "3 inches on paper" turns into "12 inches on paper"

We get

4*(3 inches on paper) = 4*(4 feet in real life)

12 inches inches on paper = 16 feet in real life

This leads to the answer C) 16 feet.

--------------------------

Alternative Method:

(3 in on paper)/(4 ft in real life) = (12 in on paper)/(x ft in real life)

3/4 = 12/x

3*x = 4*12 ... cross multiply

3x = 48

x = 48/3 .... dividing both sides by 16

x = 16

The car's length is 16 feet in real life.

Answer:

A) y = -1/2x + 2

Step-by-step explanation:

The line is negative, so you will have a negative slope

The line is crossing the y- axis at 2 so the y- intercept is 2.

Now do rise over run or rise/run

The lines rise is 2 and the run is 4

2/4 = 1/2 and since the line is negative the slope is negative -1/2

y = -1/2x + 2

Answer:

  i) exponential; values have a common ratio; f(x) = -2·4^x

  ii) linear; values have a common difference; f(x) = 4x -3

  iii) exponential; values have a common ratio; f(x) = 4·2^x

Step-by-step explanation:

Sequential, or evenly-spaced, input values will result in output values with a common difference if the function is linear. They will result in output values with a common ratio of the function is exponential.

The initial value, or y-intercept, is the value when x=0. The general form of the formulas is ...

  linear: f(x) = (common difference)·x + (initial value)

  exponential: f(x) = (initial value)·(common ratio)^x

__

i) The f(x) values have a common ratio of -8/-2 = 4, so the relation is exponential. The initial value is f(0) = -2. The equation is ...

  f(x) = -2·4^x

__

ii) The f(x) values have a common difference of 1 -(-3) = 4, so the relation is linear. The initial value is f(0) = -3. The equation is ...

  f(x) = 4x -3

__

iii) The f(x) values have a common ratio of 8/4 = 2, so the relation is exponential. The initial value is f(0) = 4. The equation is ...

  f(x) = 4·2^x

Answer:

The slope of the line is [tex]\displaystyle \frac{9}{14}[/tex].

Step-by-step explanation:

We are given the line in standard form:

[tex]9x - 14y = 28[/tex]

We need to get this into slope-intercept form in order to determine the slope of the line.

Slope-intercept form is [tex]y = mx + b[/tex], where m is our slope and b is the y-intercept.

Therefore, we need to get:

converted to:

[tex]\displaystyle 9x - 14y = 28\\\\-14y = -9x + 28\\\\\frac{-14y}{-14}=\frac{-9x+28}{-14}\\\\y = \frac{9}{14}x-2[/tex]

Therefore, by solving the equation in slope-intercept form, we see that m equals 9/14, so our slope is [tex]\displaystyle \frac{9}{14}[/tex].
