slope is negative so it goes down. y int is 4.
insert (0, 0) into equation and 0 < 4 is true so shade where the origin is.
Which points are on a graph where y varies directly with x and y = 3 when x = -3
a. (1, 1); (0, 1); (3, 3)
b. (0, 0); (4, 8); (5, 10)
c. (1, 0); (3, 2); (5, 4)
d. (-1, 1); (0, 0); (-5, 5)
A coordinate system is a method of determining the position of points or other geometric components on a manifold. The points which vary are on a graph where y varies directly with x are (-1, 1), (0, 0), and (-5, 5).
What are coordinates?A coordinate system is a method of determining the position of points or other geometric components on a manifold, such as Euclidean space, by using one or more integers, or coordinates.
Given that y varies directly with x, therefore, we can write,
y∝x
y = kx
Also, y=3 and x=-3, therefore, the value of k can be written as,
3=k(-3)
k=-1
Now, the points which vary are on a graph where y varies directly with x are (-1, 1), (0, 0), and (-5, 5).

Answer:
25.12 inches
Step-by-step explanation:
Given that,
→ Diameter = 8 in
→ Radius (r) = 8/2 = 4 in
→ π = 3.14
Formula we use,
→ 2πr
Then the circle's circumference is,
→ 2πr
→ 2 × 3.14 × 4
→ 2 × 12.56
→ [ 25.12 in ]
Thus, circle's circumference is 25.12 in.

Cost prevents one of the biggest barriers to restaurants offering healthier menu options. Fast-food chains like McDonald's have made their fortune by offering food with a long shelf life, which tends to be less healthy. As pointed out in The New Yorker, even if every restaurant in America decided to drop the fries and embrace kale and watermelon radish salads, the U.S. lacks the agricultural infrastructure to support that kind of dietary shift. Big farm crops like soybeans (for frying oil), corn (for high fructose corn syrup), and grain (livestock feed) receive millions of tax breaks and other government subsidies, making it hard for smaller farms to compete.

Answer:
See below
Step-by-step explanation:
Use the formulae directly
For a cone, with base radius = r and height = h, here are the related formula
[tex]\textrm{Slant height l} = \sqrt{r^2 + h^2}[/tex] (1)
[tex]\textrm{Lateral surface area} = \pi r l[/tex]
[tex]\textrm {Base area} = \pi r^2[/tex]
[tex]\textrm { Total Surface Area SA} = \textrm{Base Area + Lateral Area} = \pi r^2 + \pi rl = \pi r(r + l)[/tex] (2)
[tex]\textrm{Volume V = } (1/3) \pi r^2h[/tex] (3)
Therefore directly plugging in the numbers in the above equations:
Note:
l = slant height in cm
SA = total surface area in sqcm
V = Volume in cubic cm
Figure(a)
r = 4, h = 8
[tex]\textrm{l} = \sqrt{4^2 + 8^2} =\sqrt{80} = 8.944 \\\textrm{SA} = 4\pi(4 + 8.944) = 4\pi(12.944) = 162.66\\\textrm{V} = (1/3)\pi(4^2)(8) = 134.04[/tex]
Figure(b)
r = 7, h =15
[tex]\textrm{l} = \sqrt{7^2 + 15^2} =\sqrt{274} = 16.55[/tex]
[tex]\textrm{SA} = 7\pi(7 + 16.55) = 517.89[/tex]
Figure (c)
r = 5, l = 8
[tex]h = \sqrt{l^2 - r^2} = \sqrt{8^2 - 5^2} = \sqrt{39} = 6.245\\SA = \textrm{SA} = 5\pi(5 + 8) = 204.2\\V = (1/3)\pi(5^2)(6.245) = 163.5[/tex]

Answer:
Mean=49 pounds
Median=11pounds
Step-by-step explanation:
If all the cats got weighted (5, 11,11,12,10) for each cat you need to add, multiply and divide to get all the answers (P.S. you don't need to round for your answers!)
For solving the Mean you need to add up all the numbers and then divide by how many numbers there are (5+11+11+12+10÷ 5=49)
For solving the Median you need to put the numbers in smallest to biggest order to solve for this (5,10,11,11,12) and then kept crossing them out (left to right) until you get the two middle numbers (11,11) then add them both right and then divide 22 by 2 then you have your answer!

Did I do it right? Help me
We are given the statement that, If P is any odd number, then P + 2 is a prime number and we need to prove it either false or true, so as here it is written "any", so it means that the statement should be true for every and each odd number
Checking at P = 1⇒ P + 2 = 3 ↔ True
Checking at P = 3
⇒ P + 2 = 5 ↔ True
Checking at P = 5
⇒ P + 2 = 7 ↔ True
Checking at P = 7
⇒ P + 2 = 9 ↔ False
The given statement becomes false for P = 7, so the given statement is false

Answer: [tex]y=\frac{7}{2} x+10[/tex]
Step-by-step explanation:
y=mx+b
b=the y intercept
m=slope
In this graph, the y intercept is 10 so we can substitute b for that.
You find the slope with 2 points on the line.
(2,17) (6,31)
[tex]\frac{31-17}{6-2}[/tex]=[tex]\frac{14}{4}[/tex] which is simplified to [tex]\frac{7}{2}[/tex]
You can substitute m for [tex]\frac{7}{2}[/tex] now and your equation is [tex]y=\frac{7}{2} x+10[/tex]

A^2 -b^2 / a +b
Apply the difference of two squares formula to the top :
A^2 - b^2 = (a+b)(a-b)
now you have :
(A+b)(a-b) / a+b = 12
the two (a+ b)’s cancel each other out so you are left with a-b = 12
answer: a-b = 12

Take two points

m=950-940/2-1=10Equation in point slope form

[tex]y=-\dfrac{300}{7}x+1000[/tex]
Step-by-step explanation:
Method 1 (see attachment 1 with red line)
Plots the points on a graph and draw a line of best fit, remembering to ensure the same number of points are above and below the line.
Use the two end-points of the line of best fit to find the slope:
[tex]\textsf{let}\:(x_1,y_1)=(0,1000)[/tex]
[tex]\textsf{let}\:(x_2,y_2)=(7,700)[/tex]
[tex]\textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{700-1000}{7-0}=-\dfrac{300}{7}[/tex]
Input the found slope and point (0, 1000) into point-slope form of a linear equation to determine the equation of the line of best fit:
[tex]\implies y-y_1=m(x-x_1)[/tex]
[tex]\implies y-1000=-\dfrac{300}{7}(x-0)[/tex]
[tex]\implies y=-\dfrac{300}{7}x+1000[/tex]
Method 2 (see attachment 2 with blue line)
If you aren't able to plot the points, you should be able to see that the general trend is that as x increases, y decreases. Therefore, take the first and last points in the table and use these to find the slope:
[tex]\textsf{let}\:(x_1,y_1)=(1,940)[/tex]
[tex]\textsf{let}\:(x_2,y_2)=(7,710)[/tex]
[tex]\textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{710-940}{7-1}=-\dfrac{115}{3}[/tex]
Input the found slope and point (1, 940) into point-slope form of a linear equation to determine the equation of the line of best fit:
[tex]\implies y-y_1=m(x-x_1)[/tex]
[tex]\implies y-940=-\dfrac{115}{3}(x-1)[/tex]
[tex]\implies y=-\dfrac{115}{3}x+\dfrac{2935}{3}[/tex]

Suppose two lines are parallel.
Which of the following statements must be true? Select all that apply.
============================================================
Explanation:
Let's go through each answer choice one by one to see if it's true or false.
A) This is true. Parallel lines have equal slopes, but different y intercepts.B) This is true because of the corresponding angles theorem.C) This is false. The statement applies to perpendicular lines, rather than parallel ones.D) This is false in general. The only time it's true is when the consecutive interior angles are 90 degrees each. Otherwise, the statement is false.E) This is true. Let's say we drew any diagonal line we wanted. Now imagine picking a point on that line and shifting it up 5 units. Do this for another point and draw a line through the two separated points. This forms a parallel line. The upper line has been shifted up 5 units compared to the lower line.F) This is false in general. It's only true when both alternate interior angles are 90 degrees each; otherwise, it is false.
