joanne graphed a linear funtion with a slope of -4 passing through 0,-2 nick graphed the function y=-2x - 4
Answers
Answer:
Explanation:
The slope-intercept form of the equation of a line can be written as;
[tex]y=mx+b[/tex]where m = slope of the line
b = y-intercept of the line
So if Joanne graphed a linear function with a slope(m) of -4 passing through (0, -2), let's go ahead and determine the y-intercept of the line as shown below;
[tex]\begin{gathered} -2=-4(0)+b \\ -2=b \\ b=-2 \end{gathered}[/tex]Therefore, the equation of line will be y = -4x - 2 as graphed below;
Given Nick's function as y = -2x - 4, combining both graphs, we'll have the below;
The red line is Joanne's line while the blue line is Nick's line.
We can see from the above graph of both lines that Joanne's line intersects the y-axis above Nick's line's

-If we have 20 gallons, we can obtain the number of miles by plugging in the value into the equation, as shown as follows:
[tex]20=12m[/tex]Dividing both sides by 12:
[tex]\frac{20}{12}=m[/tex]Simplifying:
[tex]\frac{5}{3}=m[/tex]We can make 1.67 miles with 20 gallons.
-The domain of the function are all the Real Numbers and the Range are also the Real numbers.
-Finally, drawing the graph of the function:
The points of the table are the following:
Gallons Miles
2 24
4 48
6 72
8 96
-We can get the number of gallons needed to, make 500 miles by plugging the value 500 into the equation, as shown as follows:
[tex]500=12m[/tex]Isolating m:
[tex]\frac{500}{12}=m[/tex]Simplifying:
[tex]41.7=m[/tex]The number of gallons to make 500 miles is equal to 41.7 gallons

6. There were a total of 139 points scored in the basketballgame. The Falcons scored (9x+22) and the Mavericks scored(16x - 8). What was the Falcons score for the game?
Answers
The total score in the basket game = 139
Falcons score = 9x + 22
Maverick score = 16x - 8
Therefore,
139 = 9x + 22 + 16x - 8
collect like term
139 - 22 + 8 = 9x + 16x
125 = 25x
divide both sides by 25
x = 125/25
x = 5
Falcons score = 9x + 22
Falcons score = 9(5) + 22
Falcons score = 45 + 22
Falcons score = 67
An observation deck extends 200 feet out above a valley. The deck sits 150 feet above the valley floor. If an object is dropped from the observation deck, its height h in feet, after t seconds, is given by h=-16t^2 +150. How long will it take for the object to be 6 feet above the valley floor?
Answers
If equation of the height is h = -16[tex]t^2[/tex]+150, then the time taken for the object to be 6 feet above the valley floor is 4.28 seconds
The equation of the height h = -16[tex]t^2[/tex]+150
Where h is the height
t is the time taken
We have to find the time taken for the object to be 6 feet above the valley floor
The height = -150+6
= -144
Substitute the values in the equation
-16[tex]t^2[/tex]+150 = -144
-16[tex]t^2[/tex] = -144-150
-16[tex]t^2[/tex] = -294
[tex]t^{2}[/tex] = 18.375
t = 4.28 seconds
Hence, if equation of the height is h = -16[tex]t^2[/tex]+150, then the time taken for the object to be 6 feet above the valley floor is 4.28 seconds

What is the area of rectangle?The area of a rectangle is defined as the product of the length and width.
The rectangle is given which has:
verticals at A(-4,0), B(-3,1) C(0,-2) and D(-1,-3)
The length of segment AB = √ (-3 - (-4))² + (1 - 0)² = √ (1 + 1) = √2
The length of segment BC = √ (-3 - 0)² + (1 - (-2))² = √ (9 + 3) = √12
The area of the rectangle = length of segment AB x length of segment BC
The area of the rectangle = √2 x √12

5 people can claim joint ownership of an item and intend to divide it by the method of sealed bids. The winner offers a bid of $8,000, how much will that bidder need to put into a kitty for the other bidders to be compensated?
Answers
Step-by-step explanation:
there is one item and it cannot be split.
the winning bid was $8,000.
that means the fair share for each one of the 5 participants is
8000/5 = $1,600
the winner is getting one item with a value greater than his fair share.
so, he has to pay the difference into the kitty :
8000 - 1600 = $6,400
100 POINTS Which statement about this figure is true?
It has no rotational symmetry.
It has rotational symmetry with an angle of rotation of 90°.
It has reflectional symmetry with four lines of symmetry.
It has point symmetry
before you answer, just know it does have rotational symmetry, just not 90° so A and B are out. i'm just stumped about C and D
Answers
Answer:
It has reflectional symmetry with four lines of symmetry.
Step-by-step explanation:
======================================================
Explanation:
Choice A is false since it does have rotational symmetry. See choice B.
Choice B is close, but the "90 degrees" needs to be "45 degrees". Each 45 degree rotation of the figure has the "before" and "after" be the same.
Choice C is one of the answers. There's a vertical line of symmetry, and a horizontal one as well. Then there are two diagonal lines of symmetry. Each goes through the center. A line of symmetry is a mirror line to allow us to reflect one half over this line to get the other half.
Choice D is another answer. It has point symmetry since we can pick any point on the figure and reflect it over the center point, to land on a corresponding image point on the opposite side of the figure. For example, the northern most point reflects over the center to land on the southern most point.
Alec has a cherry tree in his yard. When he first planted it, the tree was 40 feet tall. Now it is 76 feet tall. What is the percent of increase in the height of the tree?
PLEASE HELP
Answers
Answer:
90%
Step-by-step explanation:
To find the percent of increase in the height of the tree, we need the change of the height and the original height (40 feet)
The change of height = 76 - 40 = 36 feet
Now, we need to divide the change by the original height to find the percent of increase.
36/40 = 9/10
9/10, which is then 90%.

The ethical codes of conduct of AICPA and IFAC are the two main codes most countries adopt to guide their members on how to deal with accounting information from an ethical perspective.
The fundamental principles within the Code – integrity, objectivity, professional competence and due care, confidentiality, and professional behavior – establish the standard of behavior expected of a professional accountant (PA) and it reflects the profession’s recognition of its public interest responsibility.
The common thing in all accounting codes of conduct is that "they all go into great detail on the responsibilities of accountants."

Determine if the table shows a proportional relationship. x 42.5 29.2 69.4 y 21.25 14.6 34.7 Yes, it is proportional because the ratios for y over x are all equivalent to one half. Yes, it is proportional because the ratios for y over x are all equivalent to one third. No, it is not proportional because 21.25 over 42.5 is not equal to 29.2 over 14.6. No, it is not proportional because 42.5 over 21.25 is not equal to 34.7 over 69.4.
Answers
Yes, it is proportional because the graph of these coordinates is a straight line and the ratios for [y] over [x] are all equivalent to one half.
What is proportional relationship?Proportional relationships are relationships between two variables where their ratios are equivalent. A straight line represents a proportional relationship. Mathematically -
y = kx + c
(y - c)/x = k [k is constant]
or
y = kx
k = y/x [k is constant]
Given is the following data -
[x] 42.5 29.2 69.4
[y] 21.25 14.6 34.7
In order to find if the given coordinates represent proportional relationship, plot these coordinates on graph. If the by joining the coordinate points, we get a straight line, then it represents a proportional relationship. Graph is attached with the answer. It can be seen that its graph is a straight line and hence represents a proportional relationship.
Now, the ratio of [y] by [x] -
m = (21.25 - 14.6)/(42.5 - 29.2) = 6.65/13.3 - 0.5 = 1/2
Therefore, we can say that, Yes, it is proportional because the graph of these coordinates is a straight line and the ratios for [y] over [x] are all equivalent to one half.

How many downloads of the standard version were there?Number of standard version downloads: ?
Answers
Answer: 529.3 downloads
Explanation:
Standard version size = 2.1 MB
High quality version = 4.7 MB
The high-quality version was downloaded twice as often as the standard version
H = 2 S
The total size downloaded for the two versions = 3335 MB
H + S = 3335
We have the system:
H = 2 S (a)
H + S = 3335 (b)
Put A into B
(2S ) + S = 3335
3S = 3335
S= 3335/3
S= 1,111.67 MB
Divide the total MB of standard versions by the size of each standard version.
1,111.67 / 2.1 = 529.3 downloads

Answers
The weight of the largest piece of pie is 250 gram.
