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
(Final answer)

Consider function f.
Which graph represents function f?
Answer:
The correct answer is graph Y
Step-by-step explanation:
Just took the test on Plato
The graph which represents function [tex]f(x)=\sqrt{x-1}[/tex] is the one which is given in option [tex](c)[/tex].
What is Graph?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]

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].

Kate purchased a car for $23,000. It will depreciate by a rate of 12% a year. What is the value of the car in 4 years. *
Answer:
$13,793
Step-by-step explanation:
Kate purchased a car for $23,000. It will depreciate by a rate of 12% a year. What is the value of the car in 4 years. *
The formula for Depreciation rate =
y = a(1 - r) ^t
Where
y = Value of the car after t years
a = Initial value of the car = $23,000
t= time in years = 4 years
r = Depreciation rate = 12% = 0.12)
y = $23000 (1 - 0.12)⁴
y = $13792.99328
Approximately = $13,793:

Good luckA pizzeria in San Antonio, Texas is known for making a pizza that has a 52-inch diameter. What is the area of the pizza to the nearest square inch?
Answer:
2123.992in^2
Step-by-step explanation:
Area of the pizza can be determined using the expression below
Area= (π d^2)/4
Given,
Diameter=52-inch
If we substitute we have
Area= [ π × (52)^2 ]/4
=8495.968/4
=2123.992in^2
Hence, the area of the pizza to the nearest square inch is 2123.992in^2

Unitary method is a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit. It is a method that we use for most of the calculations in math.
We are given that Vickie earned $6 an hour while working 11 hours over the weekend she put one third of what she and in a savings account
Therefore,
$6 x 11 hours = $66

30 + 6t = 11t
Subtract -6 from both sides

-6 + 6 = 0
11 - 6 = 5
30 = 5t
Divide 5 by both sides

Please answer this co-ordinate geometry year 10 exam question.
Answer: The distance between points A and B is 32 units.
Step-by-step explanation:
The general equation for a line in slope-intercept form is:
y = a*x +b
Where a is the slope, and b is the y-intercept.
We know that two lines are parallel if the lines have the same slope and different y-intercept.
Now, in this case we have the line:
5*x + 4*y = 16
We can rewrite this in slope-intecept form if we isolate the "y" in the left side:
4*y = -5*x + 16
y = (-5/4)*x + 16/4
y = (-5/4)*x+ 4
The slope is (-5/4) and the y-intercept is 4.
We know that line L₂ is parallel to this line, then this line will also have a slope equal to (-5/4) and a y-intercept equal to c.
y = (-5/4)*x + c
And we know that this line passes through the point (8, 15)
This means that when x = 8, the value of y must be 15.
We could just replace these two values in the above equation to find the value of c.
15 = (-5/4)*8 + c
15 + (5/4)*8 = c = 25
Then the line L₂ is:
y = (-5/4)*x + 25.
Now, we know that this line passes the x-axis at the point A.
The line will pass through the x-axis when y = 0, then we need to find the value of x such that y = 0.
0 = (-5/4)*x + 25
(5/4)*x = 25
x = 25/(5/4) = 20
Then point A is the point (20, 0)
And point B is when the line passes through the y-axis, this is when x = 0.
y = (-5/4)*0 + 25
y = 25
Then point B is the point (0, 25)
Now we want to find the distance between points A and B, which is equal to the distance between points (20, 0) and (0, 25).
When we have two points (a, b) and (c, d), the distance between them is:
distance = √( (a - c)^2 + (b - d)^2)
In this case, the distance between (20, 0) and (0, 25) is:
distance = √( (20 - 0)^2 + (0 -25)^2) = 32
The distance between points A and B is 32 units.

in a country , 17 out of every 20 people are literate. how many people out of 100 people in the country are literate
Answer:
85 people
Step-by-step explanation:
in a country , if 17 out of every 20 people are literate, then;
17 literate = 20 people
To get the number of literate people in 100
x literate = 100 people
Divide both expressions
17/x = 20/100
Cross multiply
20x = 17 * 100
x = 1700/20
x = 85
Hence 85 people are literate out of 100 people
