Part 1: Given triangle ABC and AC = BC, find a and the side lengths of the triangle.
a=
Side BC=
Side AC=
Part 2: Based off your knowledge of side lengths and triangles, what can you for sure classify the above triangle as
Triangle ABC:
Answers
Answer:
Part 1)
a=3; BC=10; AC=10
Part 2)
Isosceles Triangle
Step-by-step explanation:
Part 1)
We know that AC=BC.
Therefore, their lengths are equivalent.
So, we can write the following equation:
[tex]6a-8=4a-2[/tex]
Let’s solve for a. Subtract 4a from both sides:
[tex]2a-8=-2[/tex]
Add 8 to both sides:
[tex]2a=6[/tex]
Divide both sides by 2. Therefore, the value of a is:
[tex]a=3[/tex]
Now, we can substitute the value back to find AC and BC.
For AC, we have:
[tex]AC=6a-8\\[/tex]
Substitute 3 for a:
[tex]AC=6(3)-8=18-8=10[/tex]
So, the value of AC is 10.
For BC, we have:
[tex]BC=4a-2[/tex]
Substitute 3 for a:
[tex]BC=4(3)-2=12-2=10[/tex]
Therefore, both AC and BC measure 10 units, which was expected.
Part 2)
Remember that:
A triangle is scalene if all three of its sides are different. A triangle is isosceles if two of its sides are equal. And a triangle is equilateral when all of its sides are equal.We know that AC is equal to BC. So, two sides are equal.
We don’t know anything about AB. AB could or could not be equal.
Therefore, the best answer is that Triangle ABC is an isosceles triangle.

Find the value of x for which r || s.
Then find m<1 and m<2.
m<1 = 79- x
m<2 = 94- 2x
< means angle
Answers
Answer:
x=15
Step-by-step explanation:
79-15=64
94-30=64
The value of x for which r || s will be 15.
What are Parallel lines?
Parallel lines are those lines that are equidistance from each other and never intersect each other.
Given that;
Lines r and s are parallel to each other.
m ∠1 = 79 - x
m ∠2 = 94 - 2x
Since, Two lines r and s are parallel to each other.
Then, By definition of alternate angles of parallel lines;
m ∠1 = m ∠2
Now, Substitute the given values we get;
m ∠1 = m ∠2
79 - x = 94 - 2x
Subtract 79 both side,
79 - x - 79 = 94 - 2x - 79
- x = 15 - 2x
Add 2x both side,
- x + 2x = 15 - 2x + 2x
x = 15
Thus, The value of x is 15 for which r || s.

([tex]\frac{2}{3}[/tex], 2 )
Step-by-step explanation:
Given the 2 equations
3x + [tex]\frac{1}{2}[/tex] y = 3 → (1)
6x - y = 2 → (2)
Multiplying (1) by - 2 and adding to (2) eliminates the term in x, that is
- 6x - y = - 6 → (2)
Add (2) and (3) term by term to eliminate x
- 2y = - 4 ( divide both sides by - 2 )
y = 2
Substitute y = 2 into either of the 2 equations and solve for x
Substituting into (2)
6x - 2 = 2 ( add 2 to both sides )
6x = 4 ( divide both sides by 6 )
x = [tex]\frac{4}{6}[/tex] = [tex]\frac{2}{3}[/tex]
Solution is ( [tex]\frac{2}{3}[/tex], 2 )

Answers
2) 28 meters
3) 40 meters apart
B. 28 meters
C. 40 meters
Step-by-step explanation:
The surface of the ocean would be 0.
Taking this into account, 12 meters below would be 0 - 12, which is -12.
Therefore A's elevation would be -12.
For the sea bird, 28 meters above the surface, which is again 0, would be 0 + 28. B's elevation is 28.
Since the fish is 12 meters below the surface and the sea bird is 28 meters above the surface, simply add the two numbers up to get a total of 40 meters. C would be 40 meters.

Find the inverse for this relation: { (1, -3), (-2, 3), (5, 1), (6, 4) }
Answers
Answer:
(-3,1), (3,-2), (1,5), (4,6)
Step-by-step explanation:
For finding and inverse of a relationship, you simply just need to swap the x and y values. So the x will go into the y value and the y value will go into the x value.
The inverse relation for the given relation is {(-3, 1), (3, -2), (5, 1), (6, 4)}.
What is relation?A relation in mathematics can be defined as a set of a pair of elements belonging to each set. It is also called as a mapping from one set to the other.
The given relation is { (1, -3), (-2, 3), (5, 1), (6, 4) }.
The domain of the given relation is set of all the first elements of each pair and the range is the set of all the second elements of each pair.
The range and domain set can be written as,
Domain = {1 , -2, 5, 6 }
Range = {-3, 3, 1, 4}
In order to find the inverse relation the domain and range sets sre interchanged.
Thus, the inverse relation for the given relation can be written as,
{(-3, 1), (3, -2), (5, 1), (6, 4)} .
Hence, the inverse relation is given as {(-3, 1), (3, -2), (5, 1), (6, 4)}.

3rd box: 8
4th box: 11
5th box: 14
Step-by-step explanation: Plug in the formula y=3x+5. For example, you plug -1 as x, and you get y=(3)(-1)+5. 3 x -1 is -3, and then you add 5. The final answer is 2. Just do the same thing on the other boxes. Use the x values and plug it in into the formula shown.
1st: x = -1
y = 3x + 5
y = 3(-1) + 5
y = -3 + 5
y = 2
(-1, 2)
2nd: x = 0
y = 3x + 5
y = 3(0) + 5
y = 0 + 5
y = 5
