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:

$25.50

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

Answer:

450,000.

Step-by-step explanation:

The decimal point moves to the right, because 10 to the power of 4 is 10,000.

The value of 0.45 x [tex]10^4[/tex] is 4500.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

0.45 x [tex]10^4[/tex]

= 45/100 x [tex]10^4[/tex]

= 45 x 10²

= 4500

Thus,

The value of the expression is 4500.

Answer:

B = 94.9

Step-by-step explanation:

If we know 2 of the 3 angles of the triangle, we can estimate the base of the triangle as 90ft, after calculation, if the base was 90ft, side r would be 71.97584 which rounds to 94.9.

Result

Obtuse Scalene Triangle

Side r = 71.97584

Side 53* = 50.39643

Side 34* = 90

C=93°B=34°A=53°b=50.396a=71.976c=90

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:

f⁻¹(x) = 2ˣ / 9

Step-by-step explanation:

f(x) = log₂ (9x)

y = log₂ (9x)

swap y and x:    x = log₂ (9y)

solve y: 9y = 2ˣ        y = 2ˣ / 9

f⁻¹(x) = 2ˣ / 9

The equation of the inverse of the function f(x) = log2 (9x) should be considered as the [tex]f^{-1}(x) = 2^x / 9[/tex]

Since

f(x) = log₂ (9x)

So,

y = log₂ (9x)

Now

swap y and x so    x = log₂ (9y)

And, now we have to solve for y

9y = 2ˣ      

y = 2ˣ / 9

f⁻¹(x) = 2ˣ / 9

Hence, The equation of the inverse of the function f(x) = log2 (9x) should be considered as the [tex]f^{-1}(x) = 2^x / 9[/tex]
