1/3 (2 + 4) -6 = 2/3 (5 - z)
Answer:
11
Step-by-step explanation:
You can simplify everything on the left side of the equation first.
1/3 (2 + 4) - 6 = -4
-4 = 2/3 (5 - z)
Multiply both sides by 3/2 (multiplying by the reciprocal of 2/3 gets rid of the fraction)
(3/2) * -4 = 2/3 (5 - z) * (3/2)
-6 = 5 - z
-11 = -z
z = 11

What are the coordinates of the circumcenter of this triangle?
Enter your answer in the boxes.
Answer:
The coordinate of the circumcenter of the given triangle is (4, -1)
Step-by-step explanation:
The circumcenter is found by the intersection of the perpendicular bisectors of a triangle as follows;
The vertices of triangle ΔABC are A(1, 1), B(1, -3), and C(7, -3)
The coordinates of the midpoint of segment AB is 1/2(1 + 1, 1 + (-3)) = (1, -1)
The slope of segment AB = ∞, therefore, the slope of the perpendicular to segment AB = -1/∞ = 0
The line representing the perpendicular to segment AB is y = -1
The coordinates of the midpoint of segment BC is 1/2(1 + 7, (-3) + (-3)) = (4, -3)
The slope of segment BC = 0, therefore, the slope of the perpendicular to segment BC = ∞, which is a vertical line parallel to the y-axis with equation, x = 4
Therefore, the coordinate of the circumcenter is the intersection of the lines y = -1, and x = 4, which is the point (4, -1).

What are the missing values in the table?
Answer:
B: A = –5x; B = –1x; C = 5
Step-by-step explanation:
The missing values in the division table are as column (A): –5x; column (B): –1x; column (C): 5. The correct answer is option B.
To fill in the missing values in the division table, we need to perform polynomial long division to divide the dividend [tex](x^{4} - 4x^{3} + 4x^{2} - 6x + 5)[/tex]by the divisor (x – 1).
The quotient and remainder will help us complete the table.
Performing the polynomial long division, attached below image.
From the division, we can determine the values for the missing cells:
Divisor: x - 1
Quotient:

Therefore, the missing values in the table are:
column (A): –5x

Given the function g(x) = 3x – 1, find x if g(x) = –19.
Answer:
x = -6
Step-by-step explanation:
If g(x) = -19, then -19 is 3x - 1 since g(x) = 3x - 1.
So, we get the expression -19 = 3x - 1.
Add 1 on both sides: -18 = 3x
Divide both sides by 3: -6 = x

What is the equivalent decimal form for
2/40?
Answer:
decimal form: 0.05
Step-by-step explanation:
To find decimals divide them, so 2 divided by 40 is 0.05.
I hope this helped and if it did I would appreciate it if you marked me Brainliest. thank you and have a nice day!
Answer:
0.05
Step-by-step explanation:
40 x 10 = 400
2 x 10 = 20
400 ÷ 4 = 100
20 ÷ 4 = 5
5/100 = 5 ÷ 100 = 0.05

Solve the inequality below:
Which set of ordered pairs represents a function? {(0, 1), (1, 3), (1, 5), (2, 8)} {(0, 0), (1, 2), (2, 6), (2, 8)} {(0, 0), (0, 2), (2, 0), (2, 4)} {(0, 2), (1, 4), (2, 6), (3, 6)}
Answer: {(0, 2), (1, 4), (2, 6), (3, 6)}
Step-by-step explanation:
For a relation to be considered a function, each x-value needs to have one corresponding y-value--it cannot have more than 1.
Since all the other sets of ordered pairs feature points with two x-values with different y-values, the set above is the only function of the provided options.
Which of the lines below has a slope of zero?
B
D
OA. Line A
OB. Line B
OC. Line C
OD. Line D
Answer:
The answer is B but ima add this bc i need points :P
Step-by-step explanation:
The slope of line B is zero. option B is correct.
Graph of lines are shown, line with slope zero to be determine.
Slope of the line is given by m = tan[tex]\theta[/tex].
Here,
For line A the slope is m = ∞.
For line B the slope is m = 0.
For line C the slope is m = 1.
For line D the slope is m = -1.
Thus, the line with slope zero is line B.

For the straight line defined by the points ( 3 , 51 ) (3,51) and ( 5 , 87 ) (5,87) , determine the slope ( m m ) and y-intercept ( b b ). Do not round the answers.
Answer:
Intercept = - 3 ; slope = 18
Step-by-step explanation:
Given the points :
(3, 51) ; (5, 87)
x1 =3, y1 = 51, x2 = 5 ; y2 = 87
Slope intercept relation:
y = mx + c
m = slope ; c = intercept ; x and y are x, y vlayes respectively
Slope (m) = (y2 - y1) / (x2 - x1)
Slope (m) = (87 - 51) / (5 - 3)
Slope = 36 / 2
Slope (m) = 18
The intercept c :
m = 18 ; x = 5 ; y = 87
Substitute values into the slope intercept formula :
87 = 18(5) + c
87 = 90 + c
c = 87 - 90
c = - 3
Intercept = - 3

What is the central angle measure of the sector in radians?
Answer:
13π/9 rad
Step-by-step explanation:
Given the following
Area of a sector = 26πcm²
radius of the sector = 6cm
Required
central angle measure of the sector in radians
Area of a sector = Ф/2π * πr²
26π = Ф/2π * πr²
26 = Ф(6)²/2π
26 = 36Ф/2π
2π = 36Ф/26
π = 18Ф/26
26π = 18Ф
Ф = 26π/18
Ф = 13π/9 rad
Hence the measure of the central angle in radians is 13π/9 rad
