which proof has a flaw? ( i need help in my geometry class, and will give brainliest answer if is correct!!) please help :)
Answer:
The second reason is incorrect.
It should be "Transitive Property of Congruence"
Answer:
Reason 2 ( got it correct on my test)
Step-by-step explanation:
The reason must justify its corresponding statement.
Which statement best explains the value of 16 − (−3)?
The additive inverse of −3 is −3, so 16 − (−3) = 19.
The additive inverse of −3 is −3, so 16 − (−3) = 13.
The additive inverse of −3 is +3, so 16 − (−3) = 19.
The additive inverse of −3 is +3, so 16 − (−3) = 13.
Answer:
The additive inverse of −3 is +3, so 16 − (−3) = 19
negative 6 over 8 minus negative 1 over 8 = negative 5 over 8; therefore, the distance from A to B is absolute value of negative 5 over 8 equals negative 5 over 8 units
Because it is 3 units to the left of 2 on a horizontal number line
Step-by-step explanation:
The answers are the explanation.
Comment on the second question
Note that the second question asks for the distance from -6/8 to -1/8. Ordinarily, the distance from A to B would be computed as B - A. In this set of answer choices, it is computed as |A - B|. In the end, the result is the same.
Personally, I would compute the distance between points on a number line by subtracting the left point from the right point. Here, that would also correspond to B - A.
Comment on choosing 'word' answers
In a set of answers like these, one way to choose answers is simply to eliminate the ones that make a false statement. Often, you are left with only the correct answer choice.
For example, the statement "the additive inverse of -3 is -3" is a false statement, so the first two answer choices can be eliminated. Likewise, the statement 16 -(-3) = 13 is false, so that choice can be eliminated. The one remaining answer is the correct one.

Answer:
a) root77
b) 2 root77 / ~17.55 cm^2
Step-by-step explanation:
a) by using Pythagorean Theroem,
a^2 + b^2 = c^2
2^2 + b^2 = 9^2
4 + b^2 = 81
81 - 4 = b^2
77 = b^2
root77 = b
b) 1/2bh is the quation for area thus,
area = 1/2 ( 4 ) ( root77)
area = 2 root77
or area = ~17.55 cm^2
h = [tex]\sqrt{77}[/tex]
A =[tex]2\sqrt{77}[/tex]
Step-by-step explanation:Rules for solving this problem:
Isosceles triangle rules
∠C = ∠ABC = BABecause of isosceles being made up of two right triangles; using the pythagorean theorem we can deduce that
(1/2 x AC)² = BC² - h² (1/2 x AC)² = BA² - h²Area of a triangle
A = 1/2 (Base x Height) = 1/2 * bhStep 1 - Find the height
[tex]h =\sqrt{9^2 - ((1/2)AC)^2} = \sqrt{9^2 - ((1/2)~4)^2} = \sqrt{9^2 - 2^2} = \sqrt{81-4} = \sqrt {77}[/tex]
Step 2 - Find the area
[tex]A = \frac{1}{2}bh = (\frac{1}{2})(4)(\sqrt{77}) = 2 \sqrt{77}[/tex]

Solve the equation shown:
-5(x - 3) +7x = 35
x =
Answer:
10
Step-by-step explanation:
[tex]-5(x-3)+7x=35[/tex]
Distribute the 5
[tex]-5x+15+7x=35[/tex]
Combine like terms
[tex]2x+15=35[/tex]
Subtract 15 to isolate the variable
[tex]2x=20[/tex]
Divide by 2
[tex]x=10[/tex]
Answer:
x = 10
Step-by-step explanation:
Simplify by applying the distributed property: -5x - -15 + 7x = 35Simplify: -5x + 15 + 7x = 35Combine like terms: 2x + 15 = 35Subtract 15 from each side, so it now looks like this: 2x = 20Divide each side by 2 to cancel out the 2 next to x. It should now look like this: x = 10I hope this helps!
Figure 3
62°
144 what is the angle measure in degrees for thr missing variable x in figure
The value of the angle x is equal to 98°.
Given that the figure attached below.
To find the angle x, follows sum steps as:
Draw one parallel line between the given parallel lines with intersect the point x.
By linear sum,
Angle 1 on below parallel line is 180° - 144° = 36°.
Angle 2 is equal to angle 1, that is, angle 2 is equal to 36°.
Angle 3 on centre parallel line is equal to 62°.
So, the angle x is calculated as:
x = Angel 2 + Angle 3
x = 36° + 62°
x = 98°
Hence, the required angle is equal to 98°.

f(-2)=-3+2x^2
Answer:
f(-2) = 5
Step-by-step explanation:
Step 1: Define
f(x) = -3 + 2x²
f(-2) is x = -2
Step 2: Substitute and Evaluate
f(-2) = -3 + 2(-2)²
f(-2) = -3 + 2(4)

Breannas cat weighs 3200 grams. Her neighbors cat weighs 4.68 kilograms. What is the difference, in grams, of the weights of two cats
Answer:
1480 grams.
Step-by-step explanation:
3200 grams = 3200/1000
= 3.2 kgs.
Difference in weight = 4.68 - 3.20
= 1.48 kgs
= 1480 grams.
Answer:
3,200g - 4.68kg = 1480
Step-by-step explanation:
4.68k g = 4,680 g
1 kg = 1,000 g
4,680 - 3,200 = 1480
How many solutions to y=2x-3 y=-x+3
Answer:
One solution, as there is only one intersection between these two lines.
x = 2, and y = 1 (point of interesection (2, 1) )
y = 2x-3
y = -x + 3
first step is to substitute the y of one equation into the other and solve for x.
- x + 3 = 2x - 3

We can verify this value is true by substituting it back into the equations and as a result also solving for the working y value.
x = 2 -> y = 2(x) - 3
2(2) - 3 = 4 - 3 = 1
y = 1

Help, I’m stuck. Lol.
Answer:
a. height = 12
b. area = 228
Step-by-step explanation:
a. To find the height, we can use the triangle formed by the side that measures 15, the side that measures 9. and the height. The hypotenuse of the triangle(the longest side opposite of the right angle), is 15. We can then use the Pythagorean Theorem, which states that [tex]a^2+b^2=c^2[/tex], where c is the hypotenuse, and a and b are the two other sides. In this case, we need to find a leg of the triangle, not the hypotenuse. What do we do? We can first call the height a, and rearrange the Theorem into [tex]c^2-b^2=a^2[/tex]. [tex]15^2=225, 9^2=81,[/tex] and [tex]225-81=\sqrt{144}[/tex]=12. Therefore, the height of the parallelogram is [tex]\boxed{12}[/tex]
b. To find the area of the parallelogram, we can use the area formula, which is Base*Height. The base is the flat side. We can find the base by adding 9+10=19, and [tex]19\cdot12=\boxed{228}[/tex]
what are a couple ways to simplify 3(x-5)-4=17
Simplifying
3(x + -5) + -4 = 17
Reorder the terms:
3(-5 + x) + -4 = 17
(-5 * 3 + x * 3) + -4 = 17
(-15 + 3x) + -4 = 17
Reorder the terms:
-15 + -4 + 3x = 17
Combine like terms: -15 + -4 = -19
-19 + 3x = 17
Solving
-19 + 3x = 17
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '19' to each side of the equation.
-19 + 19 + 3x = 17 + 19
Combine like terms: -19 + 19 = 0
0 + 3x = 17 + 19
3x = 17 + 19
Combine like terms: 17 + 19 = 36
3x = 36
Divide each side by '3'.
x = 12
Simplifying
x = 12
