Answer:
m=1/6
Step-by-step explanation:
change in y over change in x
m=2-1/4-(-2)
m=1/6
Answer:
Equation of the line:
y = 0.16666666666667x + 1.3333333333333
or
y = 1/6x+ 4/3
When x=0, y = 1.3333333333333

Answer: [tex]\frac{-2p^2+10p-8}{p^2-4}[/tex]
This can be written as (-2p^2+10p-8)/(p^2-4) on a keyboard.
=======================================================
Work Shown:
[tex]\frac{2p}{p^2-4} + \frac{4-2p}{p+2}\\\\\\\frac{2p}{(p+2)(p-2)} + \frac{4-2p}{p+2}\\\\\\\frac{2p}{(p+2)(p-2)} + \frac{(4-2p)(p-2)}{(p+2)(p-2)}\\\\\\\frac{2p+(4-2p)(p-2)}{(p+2)(p-2)}\\\\\\\frac{2p-2p^2+8p-8}{p^2-4}\\\\\\\frac{-2p^2+10p-8}{p^2-4}\\\\\\[/tex]
---------------------
Explanations:
In step 2, I factored p^2-4 using the difference of squares rule.In step 3, I multiplied top and bottom by (p-2) so that the second fraction has a denominator of (p+2)(p-2). We can only add fractions that have the same denominator.In step 5, I used the FOIL rule to expand (4-2p)(p-2) into -2p^2+10p-8. You can use the distribution rule or the box method as alternatives.Number 5 need answers please

find the result when -18 M -4 is added to 4m - 14
Answer:
-14m - 18
Step-by-step explanation:
Hi there!
To find the answer, we will first have to merge the expressions.
-18m - 4 + 4m - 14
To simplify this, we have to combine like terms.
-18m and 4m can be added together to create -14m
-4 and -14 can be added together to make -18.
Now that our terms are simplified, the expression becomes -14m - 18.
Hope this helped!

when i solved i got -17/-1, but my calculator says it's 17! i tried searching and it said to divide the fraction to get 17, but why do i have to divide? can someone please help me, thank u!
Answer:
-17/-1 and 17 are the same so you are correct!
Step-by-step explanation:
in the fraction, -17/-1, you want to get rid of the negatives. in order to do that, you have to get rid of them on both the numerator and denominator! so the new fraction would be 17/1, and that would be simplified to just 17! so you are correct, i hope this helps!
Answer:
yes your cauculators correct, it is 17
Step-by-step explanation:
you need to divide the fraction since there are 2 negative numbers

What is the interquartile range of the data in the box plot below?
Answer:
interquartile range = 12
Option D is correct option.
Step-by-step explanation:
We need to determine the interquartile range of the data in the box plot below.
The boxplot is made up of
Minimum Value, First Quartile, Median, Third Quartile and Maximum Value
Looking at the box plot, we get:
Minimum Value: 72
First Quartile: 73
Median: 80
Third Quartile: 85
Maximum Value: 95
The formula used to find interquartile range is: [tex]Interquartile\: Range=Third\;Quartile-First\:Quartile[/tex]
Putting values of First Quartile: 73 and Third Quartile: 85 we can find interquartile range
[tex]Interquartile\: Range=Third\;Quartile-First\:Quartile\\Interquartile\: Range=85-73\\Interquartile\: Range=12[/tex]
SO, we get interquartile range = 12
Option D is correct option.
The diagonal length of a rectangle is 25 inches, and the length of the rectangle is 9 inches.
Which measurement is closest to the width of this rectangle in inches?
A) 15.8
B) 16
C) 23.3
D) 34
Answer:
Option C is the right answer.
Step-by-step explanation:
Given that:
Length of diagonal = 25 inches
Length of rectangle = 9 inches
Width of rectangle will be one of the two legs of right angled triangle and the diagonal will be the hypotenuse.
Using Pythagorean theorem;
[tex]a^2+b^2=c^2\\(9)^2+w^2=(25)^2\\81 + w^2 = 625 \\w^2 = 625-81\\w^2 = 544[/tex]
Taking square root;
[tex]\sqrt{w^2}=\sqrt{544}\\w=23.3[/tex]
Therefore,
Option C is the right answer.
We will see that the width of the rectangle is 23.3, so the correct option is C.
How to get the width if we know the length and the diagonal?
For a rectangle of length L and width W the diagonal length is given by:
D = √( W^2 + L^2)
Rewriting this for the width we get:
W = √(D^2 - L^2)
Here we know that:
D = 25 in
L = 9 in
Replacing that in the equation above we get:
W = √( (25 in)^2 - (9 in)^2 ) = 23.3
So the correct option is C.

What is a rhombus?Its a parallelogram but all sides of the same length.
A rhombus is a parallelogram whose all sides are of equal lengths.
Its diagonals are perpendicular to each other and they cut each other in half( thus, they're perpendicular bisector of each other).
Its vertex angles are bisected by its diagonals.
The triangles on either side of the diagonals are isosceles and congruent.
