Please helpz Your friend evaluates (12 + x) ÷ 6 for x = 6 and gets 13. Explain your friend's error.

Answer:

The answer is B

[tex]y<-\frac{1}{4} x+2\\[/tex]

Step-by-step explanation:

Let:

[tex](x1,y1)=(0,2)\\(x2,y2)=(4,1)\\m=\frac{1-2}{4-0}=-\frac{1}{4} \\y-y1=m(x-x1)\\y-2=-\frac{1}{4} (x-0)[/tex]

Since the line is dotted and the area is below the line:

[tex]y<-\frac{1}{4}x+2[/tex]

Step-by-step explanation:

Time in hours is directly proportional to the number of newspapers.

3 hours = 450 newspapers

=> 4 hours = 450 * (4/3) = 600 newspapers.

Hence Joy can deliver 600 newspapers in 4 hours.

Answer:

5 cm

Step-by-step explanation:

the perimeter of a square with sides of 9 cm is 36 cm so the rectangle must have the same perimeter

if the length of the rectangle is 13cm, its opposite side is also 13cm

add 13 + 13 to get 26

let 'n' = width of rectangle

perimeter = 26 + n + n

36 = 26 + 2n

2n = 10

n = 5

If the length of the rectangle is 13 cm then the width of the rectangle will be equal to 5 cm.

A shape's perimeter is the whole distance encircling it. It is the perimeter or length of the contour of any two-dimensional geometric body. The circumference of several figures could be compared based on the measurements.

As per the information given in the question,

Length of the side of the square = 8 cm

Then, use the formula of the perimeter of the square = 4 × side

= 4 × 9 = 36 cm

The length of the rectangle = 13 cm

Use the formula of the perimeter of the rectangle,

P = 2(l + w)

36 = 2(13 + w)

36 -26 = 2w

w = 10/2

w = 5 cm

[tex]\boxed{\pink{\tt\longmapsto The \ nth \ term \ of \ the \ sequence\ is \ given \ by \frac{1}{n}}} [/tex]

A sequence is given to us is , and we need to find expression for nth term of the sequence. The given sequence is ,

[tex]\boxed{\boxed{\blue{\qquad\bf 1 , \dfrac{1}{2},\dfrac{1}{3},\dfrac{1}{4},\dfrac{1}{5},\dfrac{1}{6}}}}[/tex]

When we flip the numbers , we can clearly see that the number are in Harmonic Progression.

That is when we flip the numbers they are found to be in Arithmetic Progression .

And nth term of an Harmonic Progression is :-

[tex]\boxed{\purple{\bf T_{(Harmonic \ Progression)} = \dfrac{1}{a+(n-1)d}}} [/tex]

Hence here

Substituting the respective values,

[tex]\bf\implies T_{n}= \dfrac{1}{a+(n-1)d} \\\\\bf\implies T_{n} = \dfrac{1}{1+(n-1)1}\\\\\bf\implies T_n = \dfrac{1}{1+n-1}\\\\\bf\implies\boxed{\red{\bf T_{n}=\dfrac{1}{n}}}[/tex]

Answer:

[tex]x=42[/tex]

Step-by-step explanation:

Since we use the sides opposite and adjacent to the given angle, we will use the tangent ratio:

[tex]tangentX=\frac{opposite}{adjacent}[/tex]

Insert the given values:

[tex]tanX=\frac{9}{10}[/tex]

Since we need to find the angle, use the inverse:

Solve for k by simplifying both sides of the equation, then isolating the variable.

Exact Form: k = 3/2

Decimal Form: k = 1.5

Mixed Number Form: k = 1  1/2

Hope this helps!

Answer:

k = [tex]\frac{3}{2}[/tex]

Step-by-step explanation:

Given

[tex]\frac{k}{3}[/tex] + 4 - 5k = - 2k

Multiply through by 3 to clear the fraction

k + 12 - 15k = - 6k

- 14k + 12 = - 6k ( add 14k to both sides )

12 = 8k ( divide both sides by 8 )

k = [tex]\frac{12}{8}[/tex] = [tex]\frac{3}{2}[/tex]

The slope of a graph is the rate of change between two points. To find the slope in a graph you use: [tex]\frac{rise}{run}=\frac{y}{x}[/tex]

The y goes down by 5 and right by 4 so it'll be [tex]-\frac{5}{4}[/tex]

Answer:

The average rate will be: -4

Hence, option A is correct.

Step-by-step explanation:

Given the interval

0 ≤ x  ≤ 2

From the graph, it is clear that:

at x₁ = 0, f(x₁) = 3

at x₂ = 2,  f(x₂) = -5

Using the formula to determine the average rate of change:

Average rate = [f(x₂) - f(x₁)] / [ x₂ - x₁]

                      = [-5 - 3] / [2-0]

                      = -8 / 2

                     = - 4

Therefore, the average rate will be: -4

Hence, option A is correct.

Answer:

x=2

Step-by-step explanation:

Alright for this type of problem the line CE is proportional to line FG meaning that the length of line CE is two times the length of EG. What we want to do is set up an equation that will help us solve for x. The equation would be

18-4x=6x-7 but because line CE is two time greater than line FG we have to multiply the side of EG by 2 so the new equation is

18-4x=12x-14 Now we can began to solve

step 1 : subtract 18 to each side

-4x=12x-32

step 2; subtract 12 from each side

-16x=-32

step 3: divide each side by -16

x=2
