Dylan went to the store to buy some coffee. The price per pound of the coffee is $5.75 per pound and he has a coupon for $3.25 off the final amount. With the coupon, how much would Dylan have to pay to buy 5 pounds of coffee? Also, write an expression for the cost to buy pp pounds of coffee, assuming at least one pound is purchased.
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

g(x)is shifted right 2 units
O
g(x) is shifted left 2 units
O
g(x)is shifted up 2 units
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

Ayshab walked x miles at 4 mph.
She then walked 2x miles at 3 mph.
Find Ayshab's average speed for the whole journey.
Give your answer as a mixed number.
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 :
Ayshab walked x miles at 4 mph.She then walked 2x miles at 3 mph.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.
