Factorise 12u-uv please help lol
Answer:
u(12-v)
Step-by-step explanation:
12u and -uv both have a factor of u in common, so we can pull it out to give us the factored expression u(12-v).
Note on factoring:
Remember, it's just using the distributive property in reverse! We can get our original expression back by distributing the u to the 12 and the -v.

How do you find slopes of two points for example (9, 6) and (4, 4)?
Answer:
[tex]\frac{2}{5}[/tex]
Step-by-step explanation:
Use the following equation:
slope (m) = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]
Let:
[tex](x_1 , y_1) = (4 , 4)\\(x_2 , y_2) = (9 , 6)[/tex]
Plug in the corresponding numbers to the corresponding variables:
m = [tex]\frac{6 - 4}{9 - 4} = \frac{2}{5}[/tex]
[tex]\frac{2}{5}[/tex] is your slope.
Answer:
[tex]m = \frac{2}{5} [/tex]
Step-by-step explanation:
Slope is equal to the change in y over the change in x, or rise over run.
[tex]m = \frac{change \: in \: y}{cahnge \: in \: x} [/tex]
The change in x is equal to the difference in x-coordinates and the change in y is equal to the difference in y-coordinates.
[tex]m = \frac{y2 - y1}{x2 - x1} [/tex]
Substitute in the values of x and y into the equation to find the slope.
[tex]m = \frac{4 - (6)}{4 - (9)} [/tex]
Simplify.
[tex]m = \frac{2}{5} [/tex]
Therefor, the answer is m = 2/5.

Step-by-step explanation:
HEELLLLLLLLLLLLLLLLPPPPPPPPPPP PLZZZZZZZZZ!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!1
Answer:
x = 21
Step-by-step explanation:
equation:
⇒ 44 + 6x + 10 = 180
add like terms:
⇒ 44 + 6x + 10 = 180
⇒ 54 + 6x = 180
subtract 54 on both sides
⇒ 54 - 54 + 6x = 180 - 54
⇒ 6x = 126
divide 6 on both sides
⇒ [tex]\frac{6x}{6} = \frac{126}{6}[/tex]
⇒ x = 21
to check:
44 + (6x + 10) = 180
44 + (6 x 21 + 10) = 180
44 + 136 = 180
180 = 180

Find f'(x) for the given function.
f(x) = 5/3-x
Answer:
The derivative is:
[tex]f^{\prime}(x) = -\frac{5}{x^2-6x+9}[/tex]
Step-by-step explanation:
We are given the following function:
[tex]f(x) = \frac{5}{3-x}[/tex]
Derivative of a quotient:
Suppose we have a quotient:
[tex]f(x) = \frac{g(x)}{h(x)}[/tex]
The derivative is:
[tex]f^{\prime}(x) = \frac{g^{\prime}(x)h(x) - h^{\prime}(x)g(x)}{h(x)^2}[/tex]
In this question:
Numerator [tex]g(x) = 5, g^{\prime}(x) = 0[/tex]
Denominator [tex]h(x) = 3 - x, h^{\prime}(x) = -1[/tex]
So
[tex]f^{\prime}(x) = \frac{0(3-x) - 5}{(3 - x)^2} = -\frac{5}{x^2-6x+9}[/tex]
The derivative is:
[tex]f^{\prime}(x) = -\frac{5}{x^2-6x+9}[/tex]
What is exponential growth and exponential decay?
Answer:
In exponential growth, the rate of growth is proportional to the quantity present. In other words, y′=ky. Systems that exhibit exponential growth have a constant doubling time, which is given by (ln2)/k. Systems that exhibit exponential decay have a constant half-life, which is given by (ln2)/k
Step-by-step explanation:
There is your answer good luck! - Alexsys
Answer:
In some cases with exponential functions, as the value of x increases, the value of y also increases. This is a direct relationship known as exponential growth. As the value of x increases, the value of y grows rapidly. ... This is an inverse relationship known as decay.

What is identity matrix with example.
Answer:
An identity matrix is a square matrix having 1s on the main diagonal, and 0s everywhere else. For example, the 2×2 and 3×3 identity matrices are shown below. These are called identity matrices because, when you multiply them with a compatible matrix , you get back the same matrix
Step-by-step explanation:

An identity matrix is a square matrix having 1s on the main diagonal, and 0s everywhere else. For example, the 2×2 and 3×3 identity matrices are shown below. These are called identity matrices because, when you multiply them with a compatible matrix , you get back the same matrix.
Identity Matrix is the matrix which is n × n square matrix where the diagonal consist of ones and the other elements are all zeros. It is also called as a Unit Matrix or Elementary matrix. It is represented as In or just by I, where n represents the size of the square matrix. Identity Matrix is denoted with the letter “In×n”, where n×n represents the order of the matrix.
One of the important properties of identity matrix is: A×In×n = A, where A is any square matrix of order n×n.

Give l m n find the value of x
Answer:
x=13
Step-by-step explanation:
The two angles form a straight line so they add to 180 degrees
9x+17 + 3x+7 = 180
Combine like terms
12x +24 =180
Subtract 12 from each side
12x+24-24 =180-24
12x =156
Divide each side by 12
12x/12 =156/12
x=13
circumference of circle 132cm find the area of circle is
Answer: 1386 sq.cm.
Step-by-step explanation:
2Pi r= 132
2 * 22/7 * r = 132
r = 21
Area = pi * r * r
= 22/7 * 21 * 21
= 1386 sq.cm.
