Use the properties of logarithms to evaluate each expression. log₉27-log₉9
The result of the given logarithmic expression log₉27-log₉9 is log₉ 3.
What is termed as logarithms?A logarithmic term is one that embodies a number in logarithmic form. It can also be referred to as a log term.
A quantity is also the product of two or more quantities. As a result, a term could be the product of two or even more quantities, at least one of which can be in logarithmic form. In such cases, the terms are referred to as log terms.
A quantity is also the quotient of two quantities. So, if a term is also a quotient of quantities, and at least one of the quantities can be expressed in log form, the terms are mathematically referred to as log terms.
Quotient Rule: ㏒(A/B) = ㏒A - ㏒BProduct Rule : ㏒A + ㏒B = ㏒(AB)Power Rule: n㏒A = ㏒AⁿBase Rule = ㏒ₐb = ㏒ₓb/㏒ₓaExponent Rule = e∧lnx = xNow, as per the given question;
= log₉27-log₉9
So, applying the Quotient Rule in the given expression;
= log₉ (27/9)
= log₉ 3
Thus, the given expression simplified in the logarithmic expression as log₉ 3.

Answer:
Step-by-step explanation:
Answer: I believe A is 52 degrees.
Solution: Find angle c (D + C adds up to 180 degrees cuz its a line)
So do 180-116=64 degrees
Assuming this is an isosceles triangle because the sides on d and c look equal, we know that those 2 angles add up to 128 degrees(64 + 64).
Therefore, since the shape is a triangle(adds up to 180 degrees) you just do 180 minus 128 to get angle A which is 52 degrees.
There are 3 points on a line A, B and C.
If B is between A and C what is the length of BC.
AB= x²-6x
BC= x²+20x
AC= 60-12x
Given :
B is between A and C
AB= x²-6x
BC= x²+20x
AC= 60-12x
B divide into 2 equal parts
AB and AC are equal
AC = AB +BC
60-12x = x²-6x + x²+20x
[tex]60= 2x^{2} -6x +20x +12x[/tex]
[tex]60 = 2x^{2} -6x +32x\\[/tex]

|14c+5|>7
How can I graph this?
Answer:
Step-by-step explanation:
step 1: Absolute value inequality entered
|14c+5| > 7
step 2: Clear the absolute-value bars by splitting the equation into its two cases, one for the Positive case and the other for the Negative case.
The Absolute Value term is |14c+5|
For the Negative case we'll use -(14c+5)
For the Positive case we'll use (14c+5)
step 3: -(14c+5) > 7
Multiply
-14c-5 > 7
Rearrange and Add up
-14c > 12
Divide both sides by 14
-c > (6/7)
Multiply both sides by (-1)
Remember to flip the inequality sign
c < -(6/7)
Which is the solution for the Negative Case
step 4:
(14c+5) > 7
Rearrange and Add up
14c > 2
Divide both sides by 14
c > (1/7)
Which is the solution for the Positive Case
c < -6/7
c > 1/7

What is the definition of an angle bisector?The line or line segment that divides an angle into two equal halves is known as the (interior) bisector of the an angle.
How do you compute the angle bisector?A bisector is a tool that divides an angle equally into two equal halves. Divide the number of degrees in the angle by two to determine the angle bisector.
According to the given data:If the angle bisector of ADC is the ray CE
then,
Angle ACD = ACE + ECD
ACE = ECD
So,
ACD = 2(ACE)
ACE = 1/2 (ACD)
This implies that ∠ACE = ∠DCB.

The linear equation of the table is y = 5x + 2.
when x = 20, y = 102
when y = 42, x = 8
How to find the linear equation that generates the table?Linear equation can be represented in slope intercept form as follows;
y = mx + b
where
m = slopeb = y-interceptTherefore,
m = 17 - 12 / 3 - 2
m = 5 / 1
m = 5
Therefore, let's find the y-intercept using (2, 12)
y = 5x + b
12 = 5(2) + b
12 = 10 + b
b = 12 - 10
b = 2
Therefore, the linear equation is y = 5x + 2.
when x = 20
y = 5(20) + 2 = 100 + 2
y = 102
when y = 42
42 = 5x + 2
42 - 2 = 5x
5x = 40

Write the slope-intercept equation for a line that passes through the points (-2, 4) and (3, -5)
The slope intercept equation for a line that passes through the points (-2,4) and (3,-5) is y = -9/5x ₊ 2/5.
Given the points are:
P₁ = (-2,4) = (x₁ , y₁)
P₂ = (3,-5) = (x₂ , y₂)
Therefore, the equation of the line that passes through the above points is:
y = mx ₊ b , Will be the equation to arrive to at the very end, but we need m & b, the slope and the y-intercept.
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
= ( -5 - 4 ) / ( 3 - ( -2) ) = -9 / 5
∴ m = - 9/5
Using either P₁ or P₂, plug in one of their respective x- and y-values into:
y = -9/5 x + b
substitute (3,-5)
₋5 = (₋9/5)(3) ₊ b
₋5 = ₋27/5 ₊ b
₋5₊27/5 = b
₋ 25 ₊ 27/5 = b
b = 2/5
slope intercept equation:
y = mx ₊ b
y = -9/5x ₊ 2/5
Therefore, y = -9/5x ₊ 2/5 is the equation of the line that passes through both points (-2, 4) and (3, -5).

What are parallel lines?
Parallel lines are those lines that are equidistant from each other and never meet, no matter how much they may be extended in either directions.
Given is a set of two lines parallel to each other intersected by a line. From the question, we can write -
∠A = 5x - 15
∠B = 2x + 21
Refer to the image attached.
From the figure it can be seen that -
∠B = ∠TRO = 2x + 21 [Vertically opposite angles are equal]
∠TRO = ∠POR = 2x + 21 [Alternate interior angles are equal]
∠A = ∠POR = 2x + 21 [Vertically opposite angles are equal]
It is given that
∠A = ∠B
5x - 15 = 2x + 21
3x = 21 + 15
3x = 36
x = 12
Then -
∠A = 2x + 21 = 24 + 21 = 45°
∠B = ∠A = 45°
Therefore, the value of x will be 12 and the angle measurements of ∠A and ∠B is 45°

1\b=4/2b-10 can you help me i dont know the answer so can you please help me to find the answer?
Solving the problem as per a linear equation, the value of b is found to be 1/10.
A linear equation is a form of algebraic equation in which the highest value of a variable is always equal to 1. Such an equation forms a straight line when carved on a graph.
As provided, the given equation is,
1/b = 4/2b - 10
or, 1/b = 2/b - 10 (as 4/2 = 2 )
or, 1/b - 2/b = - 10
or, 1/b ( 1 - 2) = - 10
or, - 1/b = - 10, ( we are using cross multiplication )
so, b = 1/ 10 ( as a negative sign on both sides will be nullified)
