Answer:
1
Step-by-step explanation:
13(2x-1)-3(9x-8) = 10
or, 26x-13-(27x-24) = 10
or, 26x-13-27x+21 = 10
or, 11 - x = 10
or, 11 - 10 = x
therefore, x = 1

Determine whether the triangle with vertices at the points below is scalene, isosceles, or equilateral:
(3, 4), (8, -1), (10,3)
Answer:
Step-by-step explanation:
This is a isosceles triangle, An isosceles triangle is a triangle with (at least) two equal sides. In the figure above, the two equal sides have length and the remaining side has length.
A scalene triangle is a triangle in which all three sides have different lengths. Also the angles of a scalene triangle have different measures.
In geometry, an equilateral triangle is a triangle in which all three sides have the same length. In the familiar Euclidean geometry, an equilateral triangle is also equiangular; that is, all three internal angles are also congruent to each other and are each 60°.

d. 8
Points A, B, C, and D are collinear and positioned in that order. Find the length indicated 7) Find BC if BC = 2x + 4, AD = 28, CD = 3x - 2, and AB = 3x + 2. 8) Find BD if BD = -7 + 3x, AB = 2x - 14, AC = 2x - 3, and CD = 9.
Answer:
7) BC = 10
8) BD = 20
Step-by-step explanation:
7) The segment addition theorem tells you ...
AB +BC +CD = AD
(3x+2) +(2x+4) +(3x-2) = 28
8x +4 = 28 . . . . collect terms
8x = 24 . . . . . . . subtract 4
x = 3 . . . . . . . . . divide by 8
BC = 2x+4 = 2(3) +4
BC = 10
__
8) AB +BD = AC +CD
(2x -14) +(-7 +3x) = (2x -3) +(9)
5x -21 = 2x +6
3x = 27
x = 9
BD = -7 +3x = -7 +3(9)
BD = 20

1 over 3 (2x − 8) = 4.
Answer:
X = 10
Step-by-step explanation:
1 / 3 ( 2 x -8 ) = 4
Multiply both sides by 3:
3 * 1/3 ( 2x - 8 ) = 4 * 3
Simplify :
2x-8 = 12
Add 8 to both sides :
2x-8+8=12+8
Simplify :
2x= 20
Divide both sides by 2:
2x/2 = 20/2
x = 10

Answer:
1. (10, -⁸/₃)
2. (2, ⁸/₃)
3. (12, -4)
Step-by-step explanation:
I will do the first 3 as examples.
1. Y is ⅔ of the distance from X to Z.
Y − X = ⅔ (Z − X)
The x-coordinate of Y is:
x − -6 = ⅔ (18 − -6)
x + 6 = ⅔ (24)
x + 6 = 16
x = 10
The y-coordinate of Y is:
y − 8 = ⅔ (-8 − 8)
y − 8 = ⅔ (-16)
y − 8 = -³²/₃
y = -⁸/₃
Y is at (10, -⁸/₃).
2. The ratio of XY to YZ is 1:2.
(Y − X) / (Z − Y) = 1 / 2
Cross multiply.
2 (Y − X) = Z − Y
The x-coordinate of Y is:
2 (x − -6) = 18 − x
2x + 12 = 18 − x
3x = 6
x = 2
The y-coordinate of Y is:
2 (y − 8) = -8 − y
2y − 16 = -8 − y
3y = 8
y = ⁸/₃
Y is at (2, ⁸/₃).
3. Y is ¼ of the distance from Z to X.
Y − Z = ¼ (X − Z)
The x-coordinate of Y is:
x − 18 = ¼ (-6 − 18)
x − 18 = ¼ (-24)
x − 18 = -6
x = 12
The y-coordinate of Y is:
y − -8 = ¼ (8 − -8)
y + 8 = ¼ (16)
y + 8 = 4
y = -4
Y is at (12, -4).
How many years would it take for a person in the United States to eat 1,176 pounds of turkey?
hello, whats up? i have got a question what is the answer for this equation will mark brainlest n-8= -32 and 2-4n =66
Answer:
see explanation
Step-by-step explanation:
n - 8 = - 32 ( add 8 to both sides )
n = - 24
---------------------
2 - 4n = 66 ( subtract 2 from both sides )
- 4n = 64 ( divide both sides by - 4 )
n = - 16
Find a formula for the nth term in this
arithmetic sequence:
a1 = 9, a2 = 13, a3 = 17, 24 = 21, ...
PLS help
Answer:
[tex]a_{n}[/tex] = 4n + 5
Step-by-step explanation:
The n th term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 9 and d = a₂ - a₁ = 13 - 9 = 4 , thus
[tex]a_{n}[/tex] = 9 + 4(n - 1) = 9 + 4n - 4 = 4n + 5

Step-by-step explanation:
6(2t+9)<12t-1 what is the answer
Answer:
no solutions
Step-by-step explanation:
The inequality: 6(2t+9)<12t-1
First, use distributive property
12t+54<12t-1
Now, add 1 on both sides
12t+55<12t
Subtract 12t on both sides
55<0
This is incorrect, so there are no solutions.

x = 7What is the rule for reflecting over the y axis
Answer:
Step-by-step explanation:
The rule for reflecting over the y-axis is simple. Say you have the points (-8, 7) and you plot them on the graph. Your question says to reflect those points across the y-axis. Your new coordinates would then be shown as (8, 7). As you can see, the x-value is now the opposite of the x-value before reflecting across the y-axis. I hope this helped.
The rule for reflecting the point (x, y) is (-x, y).
As, the rule for reflecting a point, line, or shape over the y-axis is to change the sign of the x-coordinate while keeping the y-coordinate the same.
In other words, if a point is originally located at (x, y), the reflected point over the y-axis will be (-x, y).
This rule can be applied to reflect individual points, as well as to reflect lines or shapes.
By applying this rule to each point or vertex of the object, the entire object can be reflected over the y-axis.
Thus, the rule for reflecting the point (x, y) is (-x, y).
