Answer:
H
Step-by-step explanation:
The fine for speeding is $17 mile per hour. Thus, for speeding for a total of x miles per hour above the posted speed limit of 30 mile per hour, there will be a fine of: 17(x - 30)
x in the equation is the speed of the driver and the negative sign in the equation shows that the driver was traveling at a total speed greater than the posted speed limit (thus, x - 30 is the speed above the posted speed limit in which the driver will be fined for)
Since the driver was fined $221, the equation becomes:
17(x - 30) = 221
divide both sides by 17
x - 30 = 221/17
x - 30 = 13
x = 13 + 30
x = 43
The driver was fined for travelling at a speed of 43 miles per hour which is 13 greater than the posted speed limit.

The geometric meaning of the word normal is perpendicular.
Answer:
A normal is an object such as a line or vector that is perpendicular to a given object. ... If normal is 90 degree to the surface, that means normal is used in 3D. Perpendicular in that case is more in 2D referring two same entities (line-line) with 90 degree angle between them.
Whats the value of x? 3x - 5(x - 5) = -7 + 2x + 12
Answer:
x = 5
Step-by-step explanation:
Given
3x - 5(x - 5) = - 7 + 2x + 12 ← distribute and simplify left side
3x - 5x + 25 = 2x + 5
- 2x + 25 = 2x + 5 ( subtract 2x from both sides )
- 4x + 25 = 5 ( subtract 25 from both sides )
- 4x = - 20 ( divide both sides by - 4 )
x = 5

Solve the system by elimination
2x – y=1
x + 3y – 4= 0
The value of x and y for the given equation by elimination method are 1 and 1 respectively.
Elimination method for solving the system of equations;The elimination method is the process of eliminating on of the variables in the system of linear equations using the addition or subtraction methods in conjunction with multiplication or division of coefficients of the variables.
According to the given question
We have two equations
[tex]2x -y =1...(1)[/tex]
[tex]x+3y-4=0...(2)[/tex]
Multiply equation (1) both the sides by 3
[tex]6x - 3y =3...(3)[/tex]
Adding equation (2) and (3)
[tex]6x+-3y+x+3y -4 =3\\7x =7\\x =1[/tex]
Substitute
x =1, in either 2x -y =1 or x + 3y -4 =0
2(1) - y =1
⇒ -y = 1 -2
⇒ -y = -1
⇒ y =1
Hence, the value of x and y is 1 and 1 respectively.

AD is a diameter of circle ABCDE . Angle BAC=22° & angle ADC=60°. AE and ED are parallel lines. Find the values of w, x,y,and z
Answer:
x = 22°
w = 30°
y = 30°
z = 52°
Step-by-step explanation:
From ΔACD,
AD is the diameter and ∠ACD is the angle subtended by the diameter.
Therefore, m∠ACD = 90°
By triangle sum theorem,
m∠DAC + m∠ACD + m∠CDA = 180°
w° + 90° + 60° = 180°
w = 180 - 150
w = 30°
AB║ED and AD is a transversal line.
Therefore, m∠BAD = m∠ADE
(w + 22)° = z°
30 + 22 = z
z = 52°
Since, ∠CEB and ∠BAC are the inscribed angles subtended by the same arc BC,
Therefore, m∠CEB = m∠BAC
x = 22°
Similarly, ∠CED and ∠DAC are the inscribed angles subtended by the same arc CD,
m∠CED = m∠DAC = 30°
y = 30°

Write a rational function with an x-intercept at (-9,0), a vertical asymptote at x=3, and a hole located at (1,-5). Then, identify the horizontal asymptote.
Answer:
The rational function is [tex]f(x) = \dfrac{x^2 + 8\cdot x - 9}{x^2 - 4 \cdot x + 3}[/tex]
The horizontal asymptote occur at y = 1
Step-by-step explanation:
Given that the function has an x-intercept at (-9, 0), we have;
(x + 9) is a factor of the function
Also, given that the function has a vertical asymptote at x = 3, we have that a factor of the denominator of the function is (x - 3)
With a hole at (1, -5), we have, (x - 1) in both the numerator and the denominator and when x = 1, f(x) = -5
The general form of the function can be presented as follows;
f(x) = ((x + 9)·(x - 1))/((x - 3)(x - 1)) = (x² + 8·x - 9)/(x² - 4·x + 3)
Given that the power of the numerator and the denominator are equal, the horizontal asymptote occur at ratio of the leading coefficient of the numerator and the denominator which from the above equation is 1/1 = 1
The horizontal asymptote occur at y = 1
