Angles DBF and EBF form a linear pair, so:
[tex]5x+6+3x-2=180 \\ \\ 8x+4=180 \\ \\ 8x=176 \\ \\ x=22 \\ \\ \implies m\angle DBF=116^{\circ}[/tex]
Similarly, because angles DBF and DBC form a linear pair,
[tex]m\angle DBC=64^{\circ}[/tex]
Since angle DBE is a straight angle, angle ABE is 26 degrees.

Geometry proofs and logics
1: The 4 angles caused by perpendicular lines are right angles
Write this in a if then statement. note:( For this one i wrote that "If the 4 angles are right angles, then the lines are perpendicular". "The other option was that, "If the lines are perpendicular, then the 4 angles are right angles." )
2: Two statements are given
1: The product of two 2-digit numbers is always a 4-digit number. Is this inductive or deductive? Why?
2: Florida requires all lawyers to pass the bar exam to practice law. If mark does not pass the bar, then he will not legally be able to represent clients as their lawyer. Is this inductive or deductive reasoning? Why?
The logic statements can be expressed and put into categories as follows;
1. If two lines are perpendicular, then the four angles caused by them are right angles
2: 1. Inductive
2. Deductive reasoning
How can the statements be expressed and evaluated?
1. If two lines are perpendicular, then the four angles caused by them are right angles.
Two lines are perpendicular when the angles formed by them are right angles.
The vertically opposite angles formed by intersecting lines have equal measure, and linear pair angles are supplementary, therefore;
If one of the angles formed by intersecting lines is known to be 90°, the vertical and adjacent angles are also 90°, and by the sum of angles at a point property, the remaining angle is also, 90°, which indicates that all the angles formed are right angles (90°).
An If, Then statement is therefore;
If two lines are perpendicular, then the four angles caused by them are right angles2. Inductive reasoning is the logic approach of making general conclusion from specific observations.
Deductive reasoning is an approach where general ideas are used to arrive at particular conclusions.
1. The statement, the product of two 2–digit numbers is always a 4–digit number, draws a general conclusion about the result of multiplying two 2–digit numbers, therefore;
The statement uses inductive reasoning2. The statements, Florida requires all lawyers to pass the Bar Exam to practice law.
If Mark does not pass the bar then he would not legally be able to represent clients as their lawyer.
The above statement makes deductions from the general statement on the rules of law practice in Florida.

Solve each equation. If necessary, round to the nearest ten-thousandth. 4³x=77.2
The solution of the given equation by rounding off it to the nearest ten-thousandth is 1.2063.
What is a round-off of the digit?
In mathematics, a round-off is defined as an approximation of the given number to a fewer number of significant digits by taking into consideration some rules.
For eg: 13.58 ~ 13.6
Solving the given equation: 4³x=77.2
We are given that 4³x = 77.2 —- 1
We know that 4³ = 64
Using in equation 1, we have,
64x = 77.2
x = 77.2 / 64
= 1.20625
Hence, the solution of the given equation rounded off to the nearest ten-thousandth is 1.2063.

The factors of the equation are -1/3 and -4/3
Rewriting the equation -
9x² + 15x + 4 = 0
ax² + bx + c = 0
Factorizing the equation such that
sum of the factors should be equal to middle expression (15x in this question)product of the factors should equal to product of (a and c) (9 and 4 in this question)12 and 3 are suitable factors for solving the given expression -
9x² + 3x + 12x+ 4 = 0
Taking common factors -
3x(3x + 1) +4 (3x + 1) = 0
(3x + 1) (3x + 4) = 0
x = -1/3, -4/3
So, the two factors of expression are -1/3 and -4/3
Checking the answers by keeping each value of x in expression
When x = (-1/3)
9x² + 15x + 4 = 0
9(-1/3)² + 15(-1/3) + 4 = 0
1 -5 +4 = 0
5 - 5 = 0
0 = 0
When x = (-4/3)
9x² + 15x + 4 = 0
9(-4/3)² + 15(-4/3) + 4 = 0
16 - 20 +4 = 0
- 4 + 4 = 0
0 = 0
Since for both values of x, Left Hand Side of equation is equal to Right Hand Side of equation, the resultant factors are correct.

Three equations with a solution of -1/2 are given as follows:
5x + 3 = 7x + 4.6x + 4 = 8x + 5.7x + 5 = 9x + 6.What is a system of equations?A system of equations is when multiple variables are related, and equations are built to find the values of each variable, according to the relations given in the problem.
One example of a system of equations is when two equations are equaled, as is the case for this problem:
ax + b = cx + d.
We want solution of -1/2, hence:
x = -1/2
(a - c)x = d - b.
Thus:
a - c = -2. -> c = a + 2.d - b = 1. -> d = b + 1.Then three possible cases are given as follows:
a = 5, c = 7, b = 3, d = 4: 5x + 3 = 7x + 4.a = 6, c = 8, b = 4, d = 5: 6x + 4 = 8x + 5.a = 7, c = 9, b = 5, d = 6: 7x + 5 = 9x + 6.More can be learned about a system of equations at https://brainly.com/question/24342899

The colors of automobiles are qualitative variables.
Qualitative data deals with traits and qualities that are difficult to quantify but can be perceptually experienced, such as flavors, sensations, looks, and colors. In general, you create quantitative data when you measure something and assign it a numerical value.
A qualitative variable, often known as a categorical variable, classifies a quality of something to characterize it. A wonderful illustration of anything that may be categorized is the hues of the cars in a parking lot: red, green, blue, black, white, etc. As a result, this is a qualitative variable.

For each function, find the inverse and the domain and range of the function and its inverse. Determine whether the inverse is a function.
f(x)=√x-5
If the inverse of f exists, it is represented by f⁻¹ and exists only if f is a bijective function.
The inverse of the function f(x)=√x-5 is x² + 5,
What is the inverse formula?The inverse function returns the original value for which the output of a function was given. When it comes to functions, f and g are inverse, with f(g(x)) = g(f(x)) = x. A function that is made up of its inverse returns the original value.
Considering f(x) = y, To find the inverse function, the x, and y values are switched giving the new equation of
x = √y - 5
Now we solve f(x),
x + 5 = √y
simplifying the above equation, we get
x² + 5 = y
The inverse function of f(x)=√x-5 is x² + 5
The domain of the function would be all x, such that
F(x) = √x + 5
The domain is {x∈R |x ≥ -5}
For f(x) to be defined, the term under the square root should be greater
than or equal to zero
x - 5 = 0
√x - 5 ≥ 0
The range of the function f(x)=√x-5 is [0,∞).
