The Anderson family paid $53 to have four pizzas delivered. Five pizzas would cost $65 and 6 pizzas would cost $77. Write an equation to represent the total cost, y, of x pizzas delivered.
Answer:
The equation is:
[tex]y =12x+5[/tex]
Step-by-step explanation:
Given
[tex](x,y) = (Pizza,Cost)[/tex]
So, we have:
[tex](x_1,y_1) = (4,53)[/tex]
[tex](x_2,y_2) = (5,65)[/tex]
[tex](x_3,y_3) = (6,77)[/tex]
Required
Equation to represent the scenario
First, calculate the slope
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
So, we have:
[tex]m = \frac{65 - 53}{5 - 4}[/tex]
[tex]m = \frac{12}{1}[/tex]
[tex]m=12[/tex]
So, the equation is:
[tex]y =m(x - x_1) + y_1[/tex]
This gives:
[tex]y =12(x - 4) + 53[/tex]
[tex]y =12x - 48 + 53[/tex]
[tex]y =12x+5[/tex]

what is the amplitude of y=4 sin 1/3 x
Answer:
4
Step-by-step explanation:
The amplitude of the sin graph is 4. Sin graphs are written as [tex]y=A sin(B(x-D))+C[/tex] where A is the amplitude. In the equation above 4 is multiplied in front of sin, which shows it is the amplitude. Since 4 is the amplitude the graph will have a range of [-4,4].

The answer is yes since there are no repeating x values.
Step-by-step explanation:
Does the point (2,-1) lie on the line
y=3-2x?
Answer:
yes
Step-by-step explanation:
the line passes through that point.
Answer:
yes
Step-by-step explanation:
Here, x=2 and y=-1
If these points lie on the line y= 3-2x,then they must satisfy the equation of the line (also mean they must be equal)
So on solving the equations putting the value of x and y, we get
y=3-2x
or,-1=3-2*2
or,-1=3-4
Therefore, -1=-1

Step-by-step explanation:
If he plans to cook 16 of less hotdogs, h is going to be equal to or less than 16. The circle is closed because he could cook 16.
Answer:
For the first question it would be answer 4
Since they ask you "at most 16 hot dogs," that means that it has to be less than or equal to 16.
For the second question, you would put the endpoint on 16 and make the arrow going left.

What are arithmetic operations?Addition, subtraction, multiplication, and division are the most fundamental operations in arithmetic. However, arithmetic also includes more complex operations like manipulating percentages, square roots, exponentiation, logarithmic functions, and even trigonometric functions, which are analogous to logarithms. It is necessary to evaluate arithmetic expressions in accordance with the intended order of operations.
Given one yard of ribbon is 3.5 dollars
1y = 3.5
where y = yards
dollar for 5/8 yards is
1y x 5/8 = 3.5 x 5/8
5/8y = 2.1875
Hence one should pay 2.1875 dollars for 5/8 yards.

Answer:
Left triangle: 12.5 cm
Right triangle: 21 cm
Trapezoid: 50 cm
Total: 83.5
Step-by-step explanation:
Left triangle: The formula to find the area of a triangle is 1/2bh, in which b=base and h=height. The base of the left triangle is 5 cm and the height is 5 cm. 5*5=25. 25/2=12.5 cm.
Right triangle: Once again, use the area formula for a triangle. The base of the right triangle is 6 cm and the height is 5+2=7. 6*7=42. 42/2=21 cm.
Trapezoid: The formula to find the area of a trapezoid is a+b/2(h) in which a and b are the top and bottom of the trapezoid and h=height. In this case, a=9 cm and b=5+6=11 cm. The height is 5 cm. 9+11=20. 20/2=10. 10*5=50 cm.
Add all of the areas. 12.5+21+50=83.5. So, the total area is 83.5 cm.
What is the relationship between the circumference of a circle and its diameter?
A. The diameter is about 3 times the circumference.
B. The circumference is a little more than 3 times the diameter.
C. The diameter is about half the circumference.
D .It depends on the circle.
Answer:B
Step-by-step explanation:
Find a circle. Measure the diameter and circumference.
You can use a tape measure, a piece of string or roll the circle along a ruler.
In every case you will find the circumference is a little more than three times bigger than the diameter.
The more accurate your measurements are, the closer you will get to pi = 3.14159...

Answer:
(x + 2)² + (y - 4)² = 16
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here (h, k ) = (- 2, 4 ) and r = 4 , then
(x - (- 2))² + (y - 4)² = 4² , that is
(x + 2)² + (y - 4)² = 16

A conical candle is to be made from 250 cm3 of wax. If the candle's height is three times its diameter, what radius and height should it have, to the nearest tenth?
Answer:
The radius and height of the cone are 3.41 cm and 20.46 cm respectively.
Step-by-step explanation:
Given that,
The volume of a conical candle is 250 cm³.
The height of candle is 3 times of its diameter.
h = 3d (d = 2r, radius)
So,
h = 6r
The formula of volume of a cone is given by :
[tex]V=\dfrac{1}{3}\pi r^2h\\\\250=\dfrac{1}{3}\pi \times r^2\times 6r\\\\250=2\pi r^3\\\\r=(\dfrac{250}{2\pi })^{1/3}\\\\r=3.41\ cm[/tex]
Height, h = 6r = 6(3.41) = 20.46 cm
Hence, the radius and height of the cone are 3.41 cm and 20.46 cm respectively.
The equation for the circle below is x2 + y2 = 16. What is the length of the
circle's radius?
Answer:
e) 4
Step-by-step explanation:
This is the form of a circle. Use this form to determine the center and radius of the circle.
(x−h)^2+(y−k)^2=r^2
r=4
h=0
k=0
Many golfers wear wrist bracelets containing magnets because they claim the magnets improve balance and the length of shots played off the tee. A golfer would like to determine if the claim has merit and finds 200 volunteers who play golf to participate in an experiment. Half of the golfers are randomly assigned to wear a bracelet with magnets, while the other half wear a bracelet without magnets. Each golfer plays normally for a month, after which the length of their shots in a subsequent round is recorded.
What is the response variable in this experiment?
a. the age of each golfer
b. the 200 volunteers
c. the length of shots played by the golfers
d. whether the golfers wear or do not wear the bracelet
Answer:
I believe it is (C), the length of the golfers.
The things measured in the experiment are the bracelet and the length of the shots based off of it. The response variable is basically the dependent variable, and theyre trying to figure out if the lengths of shots are dependent on the bracelet.
Because of this, we know A and B are already wrong.
Now we're left with C and D.
If you think of graphing D as the y variable, it just doesn't make sense. Because how would you do that? But, if you made C the y variable, you can make a bar graph, which I think would make sense in this scenario.
Which is why I believe, the length of the shots is the response variable.
