Answer:

f(5) = 14

Step-by-step explanation:

Just replace the variable "x" with "5":

f(5) = 2×5 + 4 = 14

Answer:

1

Step-by-step explanation:

Since the value of x is 4 ( because four is in the position of x) you would plug in 4 into he equation.

2(4) = 8

Then 8 - 7 = 1

F(4) is 1

Therefore, your final answer is 1.

Answer:

her hourly pay is £8.50

Step-by-step explanation:

h= hourly pay

n = number of hours worked over 40 hours in a week

week pay = 40h + (n x 2 x h)

544 = 40h + 2nh

52 - 40 = 12, so n = 12

544 = 40h + 2 x 12 x h

544 = 40h + 24h

544 = 64h

544/64 = 8.5 h=8.5 (£8.50)

just to check:

£8.50 x 40 = £340

£8.50 x 2 x 12 = 204

340 + 204 = 544 yayy the answer is correct

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

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:

84

Step-by-step explanation:

100-point test = 50 questions which are worth 2-points each.

(50 x 2 = 100)

If she got 8 wrong, this means she lost 16 points ( 8 questions x 2 points each = 16 points in total)

100 - 16 = 84

To find her score if she got x questions wrong just multiply x by 2 and subtract the answer to 100.

Answer:

The third time = 11.64 seconds

Step-by-step explanation:

Let the average time be x

The average of a set of numbers is the sum of the numbers divided by the number of terms. In this case:

Average = (10.84 + 13.52 + x) ÷ 3 = 12.0

[tex]\frac{10.84\ + 13.52\ + x}{3}= 12.0\\\frac{24.36\ +\ x}{3} = 12.0\\cross-multiplying\\24.36\ +\ x = 3 \times 12.0\\24.36\ +\ x = 36\\x = 36 - 24.36\\x = 11.64\ seconds[/tex]

Answer:

23

Step-by-step explanation:

1 + 4 = 5 so we get 1 4 5

then 4+5 = 9, 1 4 5 9

5+9 = 14, 1 4 5 9 14

9+14 = 23, so

1 4 5 9 14 23

23 is the 6th number in this sequence

The sixth number in the Fibonacci sequence with the first two numbers 1 and 4 is 23 and this can be determined by using the arithmetic operations.

Given :

Fibonacci sequence with the first two numbers 1 and 4.

The following steps can be used to determine the sixth number in the Fibonacci sequence:

Step 1 - If the first two numbers in the Fibonacci sequence is 1 and 4 then the third number is:

= 1 + 4

= 5

Step 2 - The Fourth number in the Fibonacci sequence is:

= 4 + 5

= 9

Step 3 - The Fifth number in the Fibonacci sequence is:

= 5 + 9

= 14

Step 4 - The Sixth number in the Fibonacci sequence is:

= 9 + 14

= 23

So, the sixth number in the Fibonacci sequence with the first two numbers 1 and 4 is 23.

Answer:

CB = 30.15

Step-by-step explanation:

180-58-93 = 29 degrees for angle B

draw a line perpendicular to BC down to point A, lets call the perpendicular point D.

now you've got 2 similar, smaller triangles

angle A is split into two angles, 29 degrees above and 58 degrees below.

sin 29 =CD/16

CD = 7.75

cos 29 = AD/16

AD = 14

tan 58 =DB/AD = DB/14

DB = 22.40

CD + DB = 7.75 + 22.40 = 30.15

reflection and translation.

Given:

The different transformation in the options.

To find:

The transformation that would result in the perimeter of a triangle being different from the perimeter of its image.

Solution:

In option 1,

[tex](x,y)\to (y,x)[/tex]

It represents reflection across the line y=x.

In option 2,

[tex](x,y)\to (x,-y)[/tex]

It represents reflection across the x-axis.

In option 3,

[tex](x,y)\to (4x,4y)[/tex]

It represents dilation by scale factor 4 and the center of dilation is at origin.

In option 4,

[tex](x,y)\to (x+2,y-5)[/tex]

It represents translation 2 units right and 5 units down.

We know that the reflection and translation are rigid transformations, It means the size and shape of the figure remains the same after transformation.

So, the perimeter of the figure and its image are same in the case of reflection and translation.

But dilation is not a rigid transformation. In dilation, the figure is similar to its image. So, the perimeter of the figure and its image are different in the case of dilation.

Therefore, the correct option is 3.
