Answer:
How does y vary with x?
This is called direct variation and to find proportionality, we use the formula y/x = K
Step-by-step explanation:
The first table's results would look like:
6:15
12:30
18:45
24:60
30:75
To do these, you divide the y values by the constant to receive x.

Step-by-step explanation:
Mark would need a total of 824 feet of fencing to surround all four rectangular gardens.
What is a rectangle?A rectangle is a 2-D shape with length and width.
The length and width are different.
If the length and width are not different then it is a square.
The area of a rectangle is given as:
Area = Length x width
We have,
To calculate the total length of fencing Mark needs to surround all four gardens, we first need to determine the perimeter of one rectangular garden.
The perimeter of a rectangle is given by the formula:
P = 2l + 2w,
where P is the perimeter, l is the length, and w is the width.
For one rectangular garden with a length of 60 feet and a width of 43 feet, the perimeter would be:
P = 2(60) + 2(43) = 120 + 86 = 206 feet.
Therefore, to surround all four gardens, Mark would need a total of:
4 x 206 feet = 824 feet of fencing.
Thus,
Mark would need a total of 824 feet of fencing to surround all four rectangular gardens.

Step-by-step explanation:
Answer:

Step-by-step explanation:
Slope = Rise/Run
We can find the amount between 7 and -5 as 12, and -2 and 2 as 4.
Then we can do rise/run and 12/4
Which would divide into 3.
ANd because we can see the x increases as the y decreases, we can find that it's a negative slope.

The data set, {81, 87, 71, 89}, represents Ken's test scores for the first four tests of the semester. Ken scored an 85 on the fifth test.
What impact does the 85 have on the mean test score?
Answers
(Add all numbers in set and divide by how many numbers there are)
81 + 87 + 71 + 89 = 328 / 4 = 82
Then, find the mean with the 85 added as the fifth term.
81 + 87 + 71 + 89 + 85 = 413 / 5 = 82.6
The impact that the 85 had on the mean test score was that the mean/average increased by 0.6.
Answer:
decrease
Step-by-step explanation:
If 89 is the highest score, Ken would need a score of 90+ to increase the mean.
[tex]Md < 89\\Mi >89[/tex]
Md = mean decreases
Mi = mean increases

Identifying the slope, y-intercept and x- intercept of each
Answers
Answer:
slope= -3
y-intercept= 6
Step-by-step explanation:
1. Approach
To solve this problem, one needs the slope and the y-intercept. First, one will solve for the slope, using the given points, then input it into the equation of a line in slope-intercept form. The one can solve for the y-intercept.
2.Solve for the slope
The formula to find the slope of a line is;
[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Where (m) is the variable used to represent the slope.
Use the first two given points, and solve;
(1, 3), (2, 0)
Substitute in,
[tex]\frac{(0)-(3)}{(2)-(1)}[/tex]
Simplify;
[tex]\frac{-3}{1}\\\\=-3[/tex]
3. Put equation into slope-intercept form
The equation of a line in slope-intercept form is;
[tex]y = mx + b[/tex]
Where (m) is the slope, and (b) is the y-intercept.
Since one solved for the slope, substitute that in, then substitute in another point, and solve for the parameter (b).
[tex]y=-3x+b[/tex]
Substitute in point (3, -3)
[tex]-3=-3(3)+b\\-3 = -9 + b\\6 = b[/tex]

x=4y-1
x+2y=11
Answers
Answer:
x = 7, y = 2
Step-by-step explanation:
x= 4y -1
since x is by itself 4y-1 will substitute for x in the other equation x+2y=11
it will become 4y-1+2y=11
+1 +1
add one to both sides since is doesn't have a variable.
it will become 4y+2y= 12 now add 4y+2y
becomes 6y=12
_ _
6 6
divide by 6 on each side and you get y=2.
now x=4(2)-1 you will substitute y into the first equation.
x=8-1 subtract 8 from 1 to get 7.
x=7
y=2

Why does it say it’s incorrect-
When the 982 rounded to the nearest hundred so it comes 1000.
The following information should be relevant:
At the time of rounding off the numbers, we have to look at whether the tens digit is 5 or more or it should be less than 4 or 4.If it is 5 or more so the same should be rounded up.And, if it is 4 or less so the same should be rounded down.Therefore we can conclude that When the 982 rounded to the nearest hundred so it comes 1000.
