Answer:

y=1x+1

Slope is 1

Step-by-step explanation:

Slope = rise/run.

We go up 1 and run 1. The slope is 1.

Let me double check.

The line passes through the points (-1,0) and (0,1).

m = delta y ÷ delta x

m = (0 - 1)/(-1 - 0)

m = -1/-1

m = 1

Yep. The slope is 1.

Answer:

The width of the garden is 12 feet.

The length of the garden is 20 feet.

Step-by-step explanation:

Let l be the length and w be the width

Then according to given statements

[tex]l = 2w-4\ \ \ Eqn\ 1[/tex]

Second equation is:

[tex]2l+2w = 64\ \ \ \ Eqn\ 2[/tex]

Putting l = 2w -4 in equation 2

[tex]2(2w-4)+2w = 64\\4w-8+2w = 64\\6w -8 = 64\\6w = 64+8\\6w = 72\\\frac{6w}{6} = \frac{72}{6}\\w = 12[/tex]

Putting w = 12 in equation 1

[tex]l = 2(12)-4 = 24-4 = 20[/tex]

Hence,

The width of the garden is 12 feet.

The length of the garden is 20 feet.

The compound inequality is represented by –4 ≤ x < 2 ,  Option C is the answer.

An inequality is a statement that consist of expressions equated by constants or other expressions by an inequality operator.

From the line shown below , the compound inequality has to be determined

There is an open dot on + 2 and closed dot on -4

so x  ≥ –4 , x < 2  

and this is represented by –4 ≤ x < 2

Therefore Option C is the answer.

Answer:

x = 50

Step-by-step explanation:

these are vertical angles meaning they are congruent so

[2(x+10)] = (3x-30) then use distributive property

(2x+20) = (3x-30) subtract 2x from both sides

20 = x - 30 add 30 to both sides

x = 50

Answer:

x = 50

Step-by-step explanation:

We know that 2(x+10) = (3x-30) because it is on opposite sides of an "x".

We just set them equal to each other and solve for x!

2(x+10) = 3x - 30

2x + 20 = 3x - 30

20 = x - 30

50 = x

Answer: D) All real numbers greater than or equal to -4.

Explanation:

The lowest point occurs when y = -4, which is where the vertex is located.

The range consists of y values such that y = -4 or y > -4. We can shorten that last sentence to say [tex]y \ge -4[/tex]. So y is greater than or equal to -4.

As you can probably tell, the range is the set of all possible outputs of a function.

Answer:

After solving the equation [tex]\frac{x+4}{4}=\frac{x}{x-2}[/tex] we get x=-2 and x= 4 i.e {-2,4}.

Option B is correct.

Step-by-step explanation:

We need to solve [tex]\frac{x+4}{4}=\frac{x}{x-2}[/tex]

Solving:

[tex]\frac{x+4}{4}=\frac{x}{x-2}[/tex]

Cross multiply

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

Multiplying:

[tex]x(x+4)-2(x+4)=4x\\x^2+4x-2x-8=4x\\x^2+2x-8-4x=0\\x^2-2x-8=0[/tex]

Now, we have got quadratic equation [tex]x^2-2x-8=0[/tex]

Solving this quadratic equation using quadratic formula

[tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\[/tex]

We have a=1, b=-2 and c=-8 Putting values

[tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\x=\frac{-(-2)\pm\sqrt{(-2)^2-4(1)(-8)}}{2(1)}\\x=\frac{2\pm\sqrt{4+32}}{2}\\x=\frac{2\pm\sqrt{36}}{2}\\x=\frac{2\pm6}{2}\\x=\frac{2+6}{2} \ or \ x=\frac{2-6}{2}\\x=\frac{8}{2} \ or \ x=\frac{-4}{2}\\x=4 \ or \ x=-2[/tex]

So,after solving the equation [tex]\frac{x+4}{4}=\frac{x}{x-2}[/tex] we get x=-2 and x= 4 i.e {-2,4}.

Option B is correct.

This is the equation of the sentence that has been mentioned.

Answer:

y=3/2

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

5y+ −1/2=7

Step 2: Add 1/2 to both sides.

5y+/−1/2+1/2=7+1/2

5y=15/2

Step 3: Divide both sides by 5.

5y/5

=

15/25

y=3/2

The solution of the given equation is y = 3/2.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.

The operator that performs the arithmetic operations is called the arithmetic operator.

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

/ Division operation: Divides left-hand operand by right-hand operand

For example 4/2 = 2

We have given the equation as

⇒ 5y - 1/2 = 7

Add 1/2 to both sides in the above equation.

⇒ 5y - 1/2 + 1/2 = 7 + 1/2

⇒ 5y = 15/2

Divide both sides by 5

⇒ y = 15/10

⇒ y = 3/2

Hence, the solution of the given equation is y = 3/2.

Answer:

c = 6

a = 14

l = 28

t = 18

Step-by-step explanation:

Free throws are usually worth one point each. We can assign variables and use equations to link information between Adam, Cheryl, Laura, and Tom. Then, we can just substitute in our information and solve.

"Adam scored 8 more points than Cheryl"

a = c + 8

"Laura scored twice as many points as Adam"

l = 2a

"Tom scored 10 points less than Laura"

t = l - 10

"Together the four friends scored a total of 66 points"

a + c + l + t = 66

Now we substitute in our variables and solve from there (see attached image)

c = 6

a = 14

l = 28

t = 18

Given:

Total debt ratio (total debt to total assets) = 0.365

Total debt = $500,000

To find:

The total assets.

Solution:

We know that,

[tex]\text{Total debt ratio}=\dfrac{\text{Total debt}}{\text{Total assets}}[/tex]

On substituting the given values, we get

[tex]0.365=\dfrac{500,000}{\text{Total assets}}[/tex]

[tex]\text{Total assets}=\dfrac{500,000}{0.365}[/tex]

[tex]\text{Total assets}=1369863.0137[/tex]

Therefore, the value of total assets is $1369863.0137.

Answer:

Manny: 37 years old

Jeremey: 35 years old

David: 30 years old

Step-by-step explanation:

First, we must divide 102 by 3, since there are 3 people in this scenario.

102 ÷ 3 = 34

We know that 34 is an estimate of each person's age, but there's still more work to do.

Manny is seven years older than David:

30 + 7 = 37

Jeremey is 2 years younger than Manny:

37 - 2 = 35

37 + 35 + 30 = 102

Answer:

[tex]X=12[/tex]

[tex]Y=8[/tex]

[tex]Z=4[/tex]

Step-by-step explanation:

Comencemos definiendo las variables ⇒

[tex]X:[/tex] '' Número de impresoras Epson ''

[tex]Y:[/tex] '' Número de impresoras Hp ''

[tex]Z:[/tex] '' Número de impresoras Cannon ''

Ahora , dado que tenemos las variables definidas podemos escribir el sistema de ecuaciones lineales

''El número de impresoras Epson y Hp es cinco veces el número de las Cannon''

Para esa oración escribimos la siguiente ecuación :

[tex]X+Y=5Z[/tex] (I) que se puede reescribir como

[tex]X+Y-5Z=0[/tex] (II)

''El número de impresoras Epson es el triple que el de las Cannon''

Para esa oración escribimos la siguiente ecuación :

[tex]X=3Z[/tex] (III) que se puede reescribir como

[tex]X-3Z=0[/tex] (IV)

''El total de impresoras Cannon y Hp asciende a 12''

Para ésta última frase escribimos la última ecuación :

[tex]Y+Z=12[/tex] (V)

Con (II), (IV) y (V) armamos el sistema de ecuaciones lineales :

[tex]X+Y-5Z=0\\X-3Z=0\\Y+Z=12[/tex]

Lo resolvemos a través del método de Gauss insertando el sistema en una matriz y realizando operaciones de fila entre las respectivas filas de la matriz :

[tex]\left[\begin{array}{ccxc}1&1&-5&0\\1&0&-3&0\\0&1&1&12\end{array}\right][/tex]

Realizando operaciones entre filas se lleva a la siguiente matriz equivalente :

[tex]\left[\begin{array}{cccc}1&1&-5&0\\0&-1&2&0\\0&0&3&12\end{array}\right][/tex]    En esta matriz el sistema de ecuaciones asociado es

[tex]X+Y-5Z=0\\-Y+2Z=0\\3Z=12[/tex]

De aquí encontramos que [tex]Z=4[/tex] , [tex]Y=8[/tex] y [tex]X=12[/tex]  (encontramos primero el valor de [tex]Z[/tex] en la última ecuación, de allí reemplazamos en la segunda ecuación para hallar el valor de [tex]Y[/tex]. Finalmente el valor de [tex]X[/tex] se calcula con la primera ecuación)

La solución a éste sistema de ecuaciones es

[tex]X=12[/tex]

[tex]Y=8[/tex]

[tex]Z=4[/tex]

Es recomendable reemplazar éstos valores en el sistema original para verificarlos.
