Lines x and y intersect to form adjacent angles 2 and 3 . If m ∠2=3 a-27 and m∠3=2 b+14, find the values of a and b so that x is perpendicular to y.
Using the perpendicularity concept, the values of a and b so that x is perpendicular to y are: a = 39º, b = 38º.
What are perpendicular lines?Two lines are perpendicular if when they intersect two angles of 90º are formed.
Hence, the condition for this problem is given by:
m<2 = 90º.m<3 = 90º.From condition 2, the value of a is found as follows:
3a - 27 = 90º
3a = 117º
a = 117/3
a = 39º.
From condition 3, the value of b is found as follows:
2b + 14 = 90º
2b = 76º
b = 76/2
b = 38º.

What is the expression and how the write it as a single term?Researching the problem on a search engine, the expression is given by:
3[2ln(x - 1) - ln(x)] + ln(x + 1).
Applying the distributive property, we have that:
6ln(x - 1) - 3ln(x) + ln(x + 1).
Applying the exponential property of logarithms, we have that the expression is:

If you drew a line segment from the point when Kiley arrived at the airport to the point when she reached the waiting area near the gate, at what point would the line segment end?
I'll give you more points and brainliest
The required line segment will terminate at the point on the graph where the airports' coordinates (x, y) are placed.
The graph's origin, or (0, 0), will serve as its initial coordinates. Kiley's home is represented by this point. You need to figure out where the line segment would terminate if you were to draw a segment from here that depicts Kiley's automobile travel from her residence to the airport.
What is Coordinate :Coordinates are a set of values which helps to show the exact position of a point in the coordinate plane. Coordinate Plane Meaning. A coordinate plane is a 2D plane which is formed by the intersection of two perpendicular lines known as the x-axis and y-axis.
Let the airports' coordinates be in this instance (x, y).
Moreover, if the slope of the line segment linking Kiley's home and the airport is m,
The line's equation will now be,
y = mx
c = 0
Because the line is passes from origin (0, 0)
When one of the airport's coordinates is known, another one might be found.
Therefore, the necessary line segment will terminate at the point on the graph where the airports' (x, y) coordinates are placed.

6−2(8−x)=2x−10 don't get it
Answer: 0 = 0
Step-by-step explanation: Rearrange terms: 6-2 ( -x+8 ) = 2x -10
Distribute: 6 + 2x - 16 = 2x - 10
Subtract 6 and 16: -10 + 2x = 2x - 10
Rearrange terms: 2x - 10 = 2x -10
Add ten to both sides: 2x - 10 + 10 = 2x - 10 + 10
Simplify: 2x = 2x
Subtract 2x from both sides: 2x - 2 = 2x - 2

Find the measure of the indicated angle.
Answer:
Angle FDG is 42°
Step-by-step explanation:
the whole angle GDE is an obtuse angle (greater than 90° but less than 180°), but a line is drawn at the middle to split it into 2.Each will be an acute angle.This means our answer must be acute.Mathematically ,
x+86=128
X=128-86
X=42°
to be sure,when an obtuse angle is split into two angles,it becomes 2 acute angles.
what is the answer for2 /4 times 2/3??
if angle a and angle b are supplementary angles and m∠a=x, which expressions represents the number of drgress in angle B? x-180, 180-x, x-90, 90-x
m∠b = 180° - x
That is the expression that represents the number of degrees of angle b.
Which expressions represent the number of degrees of angle B?
Two angles A and B are supplementary only if their measures add up to 180 degrees.
Then we can write the simple equation:
m∠A + m∠B = 180°
In this case, we know that we have two angles a and b that are supplementary, and the measure of angle a is equal to x, where x is a variable, then using the above equation we can write:
m∠a + m∠b = 180°
Replacing the measure of angle a by the variable we get:
x + m∠b = 180°
Solving this for the measure of angle b we get:
m∠b = 180° - x
That is the expression that represents the number of degrees of angle b.

The equivalent expression for the expression (-5cd-4)(2cd²)² is - 20c³d⁵ - 16c²d⁴.
A finite combination of symbols that are well-formed in accordance with context-dependent principles is referred to as an expression or mathematical expression. Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Consider the expression,
(-5cd - 4)( 2cd²)²
Now let x = (-5cd - 4)( 2cd²)²,
Then,
x = (-5cd - 4)( 2cd²)²
x = ( - 5cd -4 ) × (2c)² × (d²)²
x = ( - 5cd - 4) × ( 4c² ) × d⁴
x = ( -5cd - 4 ) × 4c²d⁴
Using the distributive property,
x = ( - 5cd ) × ( 4c²d⁴ ) - 4 × 4c²d⁴
x = - 20 × c³ × d⁵ - 16 × c²d⁴
x = - 20c³d⁵ - 16c²d⁴

Slope = -¹/₃Point = (-1, 0)Substitute the given slope and point into the formula and solve for b:
