Answer: Ayshab's average speed for the whole journey =  [tex]3\dfrac{3}{11}\text{ mph}[/tex]

Step-by-step explanation:

Formula: Speed = [tex]\dfrac{Distance}{Time}[/tex]

i.e. Time = [tex]\dfrac{Distance}{Speed}[/tex]

If Ayshab walked x miles at 4 mph, then time taken by him = [tex]\dfrac{x}{4}[/tex] hours

If she then walked 2x miles at 3 mph, then time for this period = [tex]\dfrac{2x}{3}[/tex] hours

Average speed = [tex]\dfrac{Total \ distance}{Total\ time}[/tex]

[tex]=\dfrac{x+2x}{\dfrac{x}{4}+\dfrac{2x}{3}}\\\\\\=\dfrac{3x}{x(\dfrac{1}{4}+\dfrac{2}{3})}\\\\\\=\dfrac{3}{\dfrac{3+8}{12}}\\\\\\=\dfrac{3\times12}{11}\\\\=\dfrac{36}{11}\\\\=3\dfrac{3}{11}\text{ mph}[/tex]

Hence, Ayshab's average speed for the whole journey =  [tex]3\dfrac{3}{11}\text{ mph}[/tex]

Ayshab's average speed for the whole journey is 36/11 mph and this can be determined by using the formula of average speed.

Given :

The formula of speed is given by:

[tex]\rm Speed = \dfrac{Distance }{Time}[/tex]

[tex]\rm Time = \dfrac{ Distance}{Speed}[/tex]

Now, the time taken by Ayshab to walk x miles at 4 mph is :

[tex]\rm t_1 = \dfrac{x}{4}[/tex]

Now, the time taken by Ayshab to walk 2x miles at 3 mph is:

[tex]\rm t_2 = \dfrac{2x}{3}[/tex]

Now, the average speed is given by the formula:

[tex]\rm Avg. \; Speed = \dfrac{Total \;Distance}{Total \; Time}[/tex]

                  [tex]=\dfrac{x+2x}{\dfrac{x}{4}+\dfrac{2x}{3}}[/tex]

                  [tex]= \dfrac{36}{11}[/tex]

Ayshab's average speed for the whole journey is 36/11 mph.

Answer:

1) 5x + 4x²(2x + 7) - 6x² - 9x

= 5x + 8x³ + 28x² - 6x² - 9x

= 8x³ + 22x² - 4x

2) the answer is 2x³ + 17x² + 25x - 50

3) the answer is y = 4x² + 14x + 18

Given that,

The points are (4,4) and (8,3)

To find,

The slope of the line.

Solution,

The slope of a line is given by the formula as follows :

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

Put x₁ = 4, y₁ = 4, x₂ = 8 and y₂ = 3

[tex]m=\dfrac{3-4}{8-4}\\\\=\dfrac{-1}{4}[/tex]

So, the slope of the line is [tex]\dfrac{-1}{4}[/tex].

Answer:the answer is A) g(x) is shifted down 2 units

Step-by-step explanation:

Since the last number after the parentheses represents the vertical shift, taking away the +2, leaves you with 0 meaning that there is no vertical shift, so the function lies on the x-axis. The graph shifts down 2 units

Answer:

5.75x-3.25

Step-by-step explanation:

one pound equals 5.75 so to get five pounds multiply it by 5

5.75×5=28.75

then subtract the 3.25 for the coupon

28.75-3.25=25.5

for equation 5.75 is your slope which you would multiply by your x to get the total cost before the coupon and 3.25 is your y intercept that you would subtract to get your total after using the coupon

Answer:

$25.50

Step-by-step explanation:

Find out how much it costs for 5 pounds of coffee, the coupon will be added into the solution later.

1 pound of coffee = $5.75

5 pounds of coffee = $5.75 x 5 = $28.75

So 5 pounds of coffee without the coupon costs $28.75.

Let's add the coupon into the working now.

5 pounds of coffee (with coupon) = $28.75 - $3.25 = $25.50

The graph which represents function [tex]f(x)=\sqrt{x-1}[/tex] is the one which is given in option [tex](c)[/tex].

Graph a diagram in which a line or a curve shows the relationship between two quantities, measurements

We have,

[tex]f(x)=\sqrt{x-1}[/tex]

For the function to be defined the numerator must not be equals to zero and there must be a positive value inside the square root.

First we will find domain for  [tex]y=\sqrt{x-1}[/tex]  now a list of [tex]x[/tex]  values can be picked.

[tex]x-1 > 0[/tex]

[tex]x > 1[/tex]

Now, Graph using the end point and a few selected points.

       1.41[tex]\left\begin{array}{ccc}x & y\\1&0\\2&1\\3 &1.41\end{array}\right[/tex]

Now, when we will plot these points on graph we will get the same raph as given in option [tex](c)[/tex].

Hence, we can say that The graph which represents function [tex]f(x)=\sqrt{x-1}[/tex] is the one which is given in option [tex](c)[/tex].
