Step-by-step explanation:
here,
x^2 -3xy-18xy^2
=x^2-(6-3)xy-18xy^2
=x^2-6xy+3xy-18y^2
=x(x-6y)+3y(x-6y)
=(x-6y)(x-3y)
may run 6 miles in 54 minutes how long will it take her to run 10 miles
Answer:
90 minutes or an hour and a half
Step-by-step explanation:
You need to find out how many minutes it takes her to run one mile, to do that you devide 54 by 6 and you get 9 minutes. Then you multiply the number of minutes per mile, 9, by 10 and you get 90 minutes.
Aboard 22 cm long is cut into two pieces. One piece is 4 cm longer than twice the length of the other piece. Find the length of each piece
Answer:
Length of one piece = 6 cm
Length of second piece = 16 cm
Step-by-step explanation:
Total Length of board = 22 cm
The board is divided into 2 pieces.
Let length of one piece = l
Length of second piece = 2l + 4
We need to find length of both pieces.
We can write the equation:
Total length = Length of one piece + Length od second piece
Putting values and finding length
[tex]22 = l+(2l+4)\\22=l+2l+4\\22=3l+4\\3l=22-4\\3l=18\\l=\frac{18}{3}\\l=6[/tex]
So, we get l= 6
Length of one piece = l =6 cm
Length of second piece = 2l + 4 = 2(6)+4 = 12+4 = 16 cm
Therefore,
Length of one piece = 6 cm
Length of second piece = 16 cm
A line passes through the points ( - 9, - 24) and (8, – 9).
Calculate the slope of the line. Write your answer as a fraction.
(If the slope is undefined, enter "DNE")
Answer:
15 / 17
Step-by-step explanation:
slope = (y2 - y1) / (x2 - x1)
= (-9 + 24) / (8 + 9)
= 15 / 17

Answer:
6 without repetition
27 with repetition
Step-by-step explanation:
without repetition, you have 3 digits to choose from initially, then only 2, then only one, i.e.:
3×2×1 = 6
with repetition, you have 3 digits to choose from for every spot:
3×3×3 = 27

Tyler ate x fruit snacks, and Han ate 3/4 less than that. Write an equation to represent the relationship between the number Tyler ate (x) and the number Han ate (y).
Answer:
0.75x = y
Step-by-step explanation:
The required expression represents the relationship between the number Tyler ate (x) and the number Han ate (y) is y = x/4.
What is the equation?The equation is the relationship between variables and represented as y = ax + b is an example of a polynomial equation.
Here,
Tyler ate x fruit snacks, and Han ate 3/4 less than that
Let the snacks eaten by Han be y,
According to the question,
y = x - 3/4x
y = x/4
Thus, the required expression represents the relationship between the number Tyler ate (x) and the number Han ate (y) is y = x/4.

17. If the cost of 8 book is Rs 520, find the cost of 10 books.
cost of 8 books = 520 AED
we can do this using direct proportion
8/520 , 10/x
(cross multiply
= 8x = 520 x 10
= 8 x 5200
x = 5200/8
x = 650 AED
therfore,
cost of 10 books is 650.

A.-2
B. 0
C. 2
D. Undefined
Answer:
Undefined
Step-by-step explanation:
If the slope was a horizontal line, then we could say y=2, however, it is only going through the x-axis so it would be x=2, but in terms of y it is undefined.
X3+x2+x+1 by grouping
Answer:
[tex]x^3+x^2+x+1=\left(x+1\right)\left(x^2+1\right)[/tex]
Step-by-step explanation:
Given the expression
[tex]x^3+x^2+x+1[/tex]
Factorized by grouping
[tex]x^3+x^2+x+1=\left(x^3+x^2\right)+\left(x+1\right)[/tex]
Factor out x² from x³+ x²: x²(x+1)
[tex]=\left(x+1\right)+x^2\left(x+1\right)[/tex]
[tex]=\left(x+1\right)+x^2\left(x+1\right)[/tex]
Factor common term x+1
[tex]=\left(x+1\right)\left(x^2+1\right)[/tex]
Therefore, we conclude that:
[tex]x^3+x^2+x+1=\left(x+1\right)\left(x^2+1\right)[/tex]

help ! need an explanation and answer!
Answer:
as below
Step-by-step explanation:
because the interior angles add up to 180 degrees.. you can solve this
180= 32 + 64 + x hmm
84 = x
so the last angle is 84° :)
as we know that the sum of three interiors angle = 180
Two angles are given 32 and 64
let the angles be a , b and c
A + B + C = 180
32 + 64 + C = 180
C = 180-96
C = 84
Hence the 3rd angle is 84

An employee is asked to calculate the chi-square value, for company data set for which observed frequency is 9.5 and expected frequency is 19. What will be the Chi-Square value
Answer:
X² =4.75
Step-by-step explanation:
The formula for calculating the chi square value is expressed as
X² = [ (O - E)²/ E ].
O is the observed frequency
E is the expected frequency
Given
O = 9.5
E = 19
Substitute into the formula:
X² = (9.5-19)²/19
X² = 9.5²/19
X² = 90.25/19
X² = 4.75
Hence the chi square value will be 4.75

Please help ❤️
Answer:
y = -2, 1, 4, 7 (in order)
Step-by-step explanation:
Plug in the value of x into the equation to find y.
For example for -1, plug in x as -1 into the equation.
y = 3(x) +1
y = 3(-1) + 1
y = -2
Similarly plug in the x to find the rest of the values for y.
