Answer:
D
Step-by-step explanation:
d is incorrect because it's saying the vertical (x) is over the horizontal change (y) and we know that's wrong because it's y/x or rise/run
The option that does not correctly refer to the slope of a line is:
a. m = [tex]\frac{x_2-x_1}{y_2-y_1}[/tex]
Option A is the correct answer.
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
We have,
The slope of a line:
a.
m = [tex]\frac{x_2-x_1}{y_2-y_1}[/tex]
The slope formula is:
m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
So,
m = [tex]\frac{x_2-x_1}{y_2-y_1}[/tex] is not correct.
b. it represents the steepness of a line.
The slope of a line is the steepness of the given line on the graph.
It is correct.
c. m = rise/run
The slope can also be termed as rise/run.
It is correct.
d. it is the ratio of the vertical change to the horizontal change
The slope of a line is given as:
m = Vertical change / Horizontal change
It is correct.
Thus,
The option that does not correctly refer to the slope of a line is:
a. m = [tex]\frac{x_2-x_1}{y_2-y_1}[/tex]
Option A is the correct answer.

Step-by-step explanation:
24 + 32 = _ (3 +4) Grid in the number that makes the equation below true.
Hey there!
24 + 32 = __?__ (3 + 4)
• SOLVING FOR THE LEFT SIDE OF THE EQUATION
24 + 32
= 56
• FIND THE GCF (Greatest Common Factor) OF THE NUMBERS TO SEE WHAT POSSIBLY GOES IN THE BLANK (also known as your result) OR THE EQUATION ON THE RIGHT SIDE
° 24: 1, 2, 3, 4, 6, 8, 12, & 24
° 32: 1, 2, 4, 8, 16, & 32
° LIKE TERMS: 1,2, 4, & 8
° GREATEST NUMBER: 8
° GCF: 8
• So, the number that goes in the blank is: 8
• TESTING TO SEE IS EQUIVALENT TO THE LEFT SIDE (THE EQUATION ON THE RIGHT SIDE OF THE PROBLEM)

Write the equation of the line in fully simplified slope intercept form
Answer:
y = -x - 8
Step-by-step explanation:
I don't know what it means by "fully symplified", but this is how I would answer.
Hope this helps, and if not, I'm sorry!
Answer:
[tex]y=-x-8[/tex]
Step-by-step explanation:
Slope intercept form is in the general form
[tex]y=mx+b[/tex] such that [tex]m[/tex] is the slope of the line, and that [tex]b[/tex] is the y-intercept of that line.
The equation for slope can be denoted as any of those below
[tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex] Where the y and x terms are from two ordered pairs
[tex]m=\frac{rise}{run}[/tex], such that rise is the vertical change in a line, and run the run is the horizontal change
Work!
In this case, since we are given nothing but a line, we should use [tex]m=\frac{rise}{run}[/tex]
Since the graph goes down by 1 for every 1 distance to the right, the change in rise of y (-1) divided by the run of x (1) means that [tex]m=-1[/tex]
We now have [tex]y=-x+b[/tex]
Since b is the y-intercept, according to the graph [tex]b=-8[/tex]
This leaves you with the final answer of [tex]y=-x-8[/tex]
Hope this helps! :)

Mr James gives £500 to his children Ally,
Barry and Cat in the ratio 2:3:5.
How much do they each receive?
Answers:
Ally gets 100 poundsBarry gets 150 poundsCat gets 250 pounds=====================================================
Work Shown:
x = some positive real number
2x = amount Ally gets
3x = amount Barry gets
5x = amount Cat gets
Note that the ratio 2x:3x:5x reduces to 2:3:5 after dividing all parts by x.
Add up the parts and you should get a sum of 500 pounds. Solve for x.
2x+3x+5x = 500
10x = 500
x = 500/10
x = 50
Based on that x value, we then can say:
2x = 2*50 = 100 pounds is what Ally gets3x = 3*50 = 150 pounds is what Barry gets5x = 5*50 = 250 pounds is what Cat getsAs a check, 100+150+250 = 500.
Also, note that the ratio 100:150:250 fully reduces to 2:3:5 after dividing all parts by the GCF 50.
Those two facts help confirm our answers.
The table shows the predicted and actual amount of snow for a local city.
Snowfall (inches)
Predicted 6.75
Actual 10.25
What is the percent error for the amount of snowfall? Round the percent to the nearest tenth if necessary.
Using it's concept, it is found that the percent error for the amount of snowfall was of 51.85%.
The percent error of an amount is the absolute value of the difference between the actual amount and the expected amount, multiplied by 100% and divided by the expected amount.
In this problem:
Expected amount: 6.75 inches.Actual amount: 10.25 inches.Then, the percent error is:
[tex]P = \frac{|10.25 - 6.75|}{6.75} \times 100\% = 51.85\%[/tex]
The percent error was of 51.85%.

What is the total volume of all four lockers

The volume of the prism if one side of a locker is 2 feet long is 32ft³
The formula for calculating the volume of a rectangular prism is expressed according to the formula
[tex]V = lwh[/tex]
l is the length
w is the width
h is the height
From the diagram;
length = s + s + s + s = 4s
width = s
height = s
Substitute the given parameters into the formula to have:
[tex]V = 4s \times s \times s\\V =4 s^3 units^3[/tex]
b) If the length of one side of a locker is 2 feet long, the volume will be expressed as:
[tex]v = 4(s)^3\\v=4(2)^3\\v=4(8)\\v=32ft^3[/tex]
Hence the volume of the prism if one side of a locker is 2 feet long is 32ft³
