The answers to all parts are given below.
What is triangle?A triangle is a polygon with three edges and three vertices. The sum of all the angles of a triangle is 180 degrees. Mathematically -
∠x + ∠y + ∠z = 180°
The sum of two sides of a triangle is greater then the third side. Mathematically -
a + b > c

Answer:
I think it's the third choice because line segments are congruent and not equal. Line segments also have little lines on top of the letters.
Step-by-step explanation:
======================================================
Explanation:
AB = BC refers to the fact that expressions 2x+7 and 4x-3 are equivalent. They represent numbers when we replace x with some number. So after doing that replacement, we have something in the form number = number.
So this is why choice A is one of the answers.
[tex]\overline{AB} \cong \overline{BC}[/tex] says "segment AB is congruent to segment BC". The horizontal lines over the lettering indicates we have a segment. The equal sign with a squiggle over top is the congruence symbol. In geometry, we say two items are congruent if they are the same. You can think of making a clone of the object and then sliding it over. In this case, we've cloned segment AB to form segment BC.
This is why choice C is the other answer.
--------------
Choices B and D are close, but not quite correct. Choice B is missing the segment markers. Choice D is missing the congruence symbol. Congruence and equality are very similar ideas, so often they get mixed up.

solve. 3(x-6)-2(2x+3)=14
Answer:
x=-38
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
3(x−6)−2(2x+3)=14
(3)(x)+(3)(−6)+(−2)(2x)+(−2)(3)=14(Distribute)
3x+−18+−4x+−6=14
(3x+−4x)+(−18+−6)=14(Combine Like Terms)
−x+−24=14
−x−24=14
Step 2: Add 24 to both sides.
−x−24+24=14+24
−x=38
Step 3: Divide both sides by -1.
−x
−1
=
38

x=−38

Please help? I don’t get this it’s really tough...
Answer:
D. 200-2/3x=2/5
Step-by-step explanation:
You can tell that one side of the equation is going to have only 2/5 because the problem said there was 2/5 of a ton left. You can also figure out that the equation should say 200-2/3x because the problem said that the conveyor belt removes 2/3 of a ton per minute. So, the equation should be...
200-2/3x=2/5, which is D.
Hope this helps c:
Answer: D
Step-by-step explanation:
The 2/3 is the rate and there is 2/5 leftover from the original 200 tons.

The average price of a movie ticket in the United States from 1980 to 2000 can be modeled by the expression, 2.75+0.10x, where x is the number of years since 1980. Which part of the expression corresponds to the cost of movie tickets in 1980?
Answer:
2.75
Step-by-step explanation:
Here, we want to find which part of the formula corresponds to the cost of movie tickets in 1980
The expression to find the cost is
2.75 + 0.10x
Now, x is the time since 1980
1980 is thus the starting position. The value of x at this point is 0, we simply thus make a substitution;
2.75 + 0.1(0)
=
2.75
The interpretation of the given model is required.
The cost of a movie ticket in the year 1980 was $2.75.
The given expression is
[tex]y=2.75+0.1x[/tex]
The point slope form of a line is
[tex]y=mx+c[/tex]
where,
m = Slope
c = Y intercept
The cost of movie ticket increases by $0.10 every year after 1980.
Here, [tex]x[/tex] is the number of years that have passed after 1980.
So, when [tex]x=0[/tex] it will correspond to the cost of ticket in 1980.
[tex]y=2.75+0.1\times 0\\\Rightarrow y=2.75[/tex]
The cost of a movie ticket in the year 1980 was $2.75.

Find the slope y intercept and x intercept and write in y=mx+b
Answer:
Slope (m) = (-1/6)
y-intercept (b) = (-3.5)
x-intercept (x) = (-21)
y = mx + b
y = (-1/6)x - 3.5
Explanation:
y = (-1/6)x - 3.5
0 = (-1/6)x - 3.5
3.5 = (-1/6)x
(-1/6)x * -6 = x
3.5 * -6 = -21
-21 = x

Lamar used a coordinate plane to show where his posters are displayed on his bedroom wall. Three posters are located at Q(4, 2), R(–3, 2), and S(–3, 5). Use the absolute value of the coordinates to find the distances between points Q and R, and between points R and S.
Answer:
Distance between the points Q and R is 1 unit while the distance between the points R and S is 3 units
Step-by-step explanation:
Here, we want to use the absolute value of the coordinates to find the distances.
Since we are using absolute values, the negative points becomes positive;
Thus;
Q = (4,2)
R = (3,2)
S = (3,5)
Mathematically, the distance between two points in the Cartesian plane can be calculated using the formula;
D = √(x2-x1)^2 + (y2-y1)^2
The distance QR is thus;
D = √(3-4)^2 + (2-2)^2
D = √(-1)^2 + 0
D = √1 = 1 unit
The distance RS is thus;
D = √(3-3)^2 + (5-2)^2
D = √(0) + (9)
D = √9 = 3 units
