Answer:

-121 feet

Step-by-step explanation:

If itś 121 feet below sea level than it would be -121 feet

The signed number -121 represents an elevation of 121 feet below sea level in the context of the valley.

To represent the elevation of a point in a valley that is 121 feet below sea level as a signed number, we can use a negative sign (-) to indicate a position below sea level.

Therefore, the signed number to represent this elevation would be -121. The negative sign (-) indicates that the elevation is below sea level, and the magnitude of the number (121) represents the distance below sea level, which is 121 feet in this case.

In summary, the signed number -121 represents an elevation of 121 feet below sea level in the context of the valley.

Answer:

f(x) = [tex]\frac{1}{16}[/tex] (x - 2)² + 2

Step-by-step explanation:

From any point (x, y ) on the parabola the focus and the directrix are equidistant.

Using the distance formula

[tex]\sqrt{(x-2)^2+(y-6)^2}[/tex] = | y + 2 | ← square both sides

(x - 2)² + (y - 6)² = (y + 2)² ← subtract (y + 2)² from both sides

(x - 2)² + (y - 6)² - (y + 2)² = 0 ← subtract (x - 2)² from both sides

(y - 6)² - (y + 2)² = - (x - 2)² ← expand left side using FOIL and simplify

y² - 12y + 36 - y² - 4y - 4 = - (x - 2)²

- 16y + 32 = - (x - 2)² ← subtract 32 from both sides

- 16y = - (x - 2)² - 32 ← divide all terms by - 16

y = [tex]\frac{1}{16}[/tex] (x - 2)² + 2

Answer:

70 degrees

Step-by-step explanation:

If cosm<A = 342/1000, we are to find the value of a

Take arccos of both sides

cosm<A = 342/1000

cosm<A = .342

arccos(cosm<A) = arccos(0.342)

m<A = arccos(0.342)

m<A = 70 degrees

Hence the measure of m<A is 70 degrees

Answer: (-2, 10)

Explanation: Since one equation has a +4y and the other equation has

a -4y, when we add the equations together, the y's will cancel out.

So we have 23x = -46 and x = -2.

To find y, plug -2 back in for x in either of the two original equations.

I've chosen to plug -2 into the first equation to get 10(-2) + 4y = 20.

Solving from here, y = 10.

So our final answer is the ordered pair (-2, 10).

Now, check your answer.

Answer:

 it would be 9/8 as the perimeter

Step-by-step explanation:

you would add all the sides together

1/8+3/4+1/4 = 9/8

Answer:

1 1/8 in.

Step-by-step explanation:

you have to add up all of the sides. 3/4 plus 1/4 equals 1. 1 plus 1/8 equals 1 1/8. Hope I helped you : )

Answer:

x = 8

Step-by-step explanation:

-4x + 6(6 - 2x) = -7x - 36

-4x + 36 - 12x = -7x - 36

-16x + 36 = -7x - 36

      +36           +36

-16x + 72 = -7x

+16x           +16x

72 = 9x

Answer: 20/3

Step-by-step explanation:

To write 6 2/3 as a fraction greater than 1, we simply have to convert it from a mixed fraction to an improper fraction. This will be:

6 2/3 = [(6 × 3) + 2]/3

= (18 + 2)/3

= 20/3

Therefore, the answer is 20/3.

Answer:

Luis quiere recibir 200$ de más por mes.

Step-by-step explanation:

Para podr calcular esto, necesitamos escribir la desigualdad dada, y para ello debemos transformar el lenguaje a lenguaje algebraico.

tres medios de la cantidad deseada:  3/2 x

mas 4100 (en este caso debería ser $100, y fue un error de tipeo): + 100

son mayor o igual a $700:  ≥ 700

Inecuación: 3/2 x + 100 ≥ 700

Ahora solo nos queda resolver el valor de x de esta inecuación. El resultado nos dirá cuanto quiere recibir al mes, por lo que la resta de esta cantidad con la cantidad que recibía antes nos dirá cuanto de más desea recibir:

3/2 x + 100 ≥ 700

3/2 x ≥ 700 - 100

3/2 x ≥ 600

3x ≥ 600 * 2

x ≥ 1200 / 3

x ≥ 400

Por tanto, Luis desea recibir al mes $400, lo que se traduce en que quiere recibir de más

400 - 200 = 200

Luis desea recibir de mas $200.

Answer:

Apple cost $0.85

Banana cost $1.2

Step-by-step explanation:

Given data

let the number of apples be x

and the number of bananas be y

Patricia bought 5 apples and 7 bananas for $12.65

5x+7y= 12.65----------1

Jose bought 10 apples and 8 bananas for $18.10

10x+8y= 18.10-----------2

solve 1 and 2 above

5x+7y= 12.65 X 2

10x+8y= 18.10 X 1

 10x+14y= 25.3

- 10x+8y= 18.10

         6y= 7.2

y= 7.2/6

y= 1.2

put y= 1.2 in 1

5x+7(1.2)= 12.65

5x+ 8.4= 12.65

5x= 12.65- 8.4

5x= 4.25

x= 4.25/5

x= 0.85

Hence each apple cost $0.85

Banana cost $1.2
