Which statement about triangle ABC is true?
A. Since two of the sides have slopes that are negative reciprocals, it is a right triangle.
B. Since two of the sides are congruent, it is a right triangle.
C. Since none of the sides have slopes that are negative reciprocals, it is not a right triangle.
D. Since none of the sides are congruent, it is not a right triangle.
Answers
Answer:
D. Since none of the sides are congruent, it is not a right triangle.
Step-by-step explanation:
This is the weirdest triangle I've ever seen.
Since none of the sides have slopes that are negative reciprocals, it is not a right triangle. Therefore, option C is the correct answer.
The given triangle ABC has vertices A(-3, -5), B(0, 4) and C(2, 5).
What is slope of a line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The formula to find the slope of a line is slope = (y2-y1)/(x2-x1)
Here, slope of AB is
m= (4+5)/(0+3)
= 3
Slope of BC is
m= (5-4)/(2-0)
= 1/2
= 0.5
Slope of CA is
m= (5+3)/(2+3)
= 8/5
= 1.6
Since none of the sides have slopes that are negative reciprocals, it is not a right triangle. Therefore, option C is the correct answer.

3/5
Step-by-step explanation:
We want to find 3/4 of 4/5.
The keyword of tells us that we need to multiply. Therefore:
[tex]\frac{3}{4}\times\frac{4}{5}[/tex]
Multiply:
[tex]=12/20=3/5[/tex]
So, 3/4 of 4/5 is 3/5.
We can confirm this by converting them to decimals.
4/5 is 0.8.
3/4 is 0.75.
0.75 or 75% of 0.8 is indeed 3/5 or 0.6.

what is the solution set of the above question ?
Answers
Answer:
The solution set is { } or ∅ ⇒ empty set
Step-by-step explanation:
∵ 2x + 10 < 10
→ Subtract 10 from the two sides of the inequality
∵ 2x + 10 - 10 < 10 - 10
∴ 2x < 0
→ Divide both sides by 2
∴ [tex]\frac{2x}{2}[/tex] < [tex]\frac{0}{2}[/tex]
∴ x < 0
∴ The solutions are all the negative numbers
∵ x ∈ N
∵ N is the set of Natural numbers
→ The natural numbers start at 1 and include all positive whole numbers
∴ N = {1, 2, 3, 4, 5, ..............}
∵ N does not contain any negative numbers
∴ The solution set is an empty set ⇒ ∅
∴ The solution set is { } or ∅

1667
16670
Step-by-step explanation:
Any number to the zeroth power is 1, so the first one is 1 x 16.67, which equals to 16.67
10 to the first power is just 10, so multiply 10 x 16.67 for the second one. This equals 166.7
10 to the second power is 10 x 10 or 100, so multiply 100 x 16.67, which is 1667.
10 to the third power is 10 x 10 x 10 or 1000, so multiply 1000 x 16.67, which is 16670.
Basically, for each one, starting with 10 to the first power, move the decimal to the right one place.

Answer:
x = 2
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define equation
4(x - 1) = 2(6 - 2x)
Step 2: Solve for x
Distribute: 4x - 4 = 12 - 4xAdd 4x on both sides: 8x - 4 = 12Add 4 to both sides: 8x = 16Divide 8 on both sides: x = 2Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 4(2 - 1) = 2(6 - 2(2))Multiply: 4(2 - 1) = 2(6 - 4)Subtract: 4(1) = 2(2)Multiply: 4 = 4Here we see that 4 does indeed equal 4.
∴ x = 2 is a solution of the equation.

MY EXPLANATION THAT HOW TO GET THE SQUARE:
Trying to factor as a Difference of Squares:
4.1 Factoring: 4x2 - 9
Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A2 - AB + BA - B2 =
A2 - AB + AB - B2 =
A2 - B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression.
Check : 4 is the square of 2
Check : 9 is the square of 3
Check : x2 is the square of x1
Factorization is : (2x + 3) • (2x - 3)

At an electronics store, a smart phone is on sale for 35% off the original price of $679. If you use the store credit card, you can receive an additional 15% off the sale price. What is the final price of the smart phone if you use the store credit car
Answers
Answer:
The final price of the smart phone if you use the store credit card is $339.5
Step-by-step explanation:
Given;
original price of the smart phone = $679
initial discount = 35%
additional discount if you use the store credit card = 15%
total discount of the smart phone if you use the store credit card
= 35% + 15% = 50%
The final price of the smart phone, if you use the store credit card is given as;
P = 0.5 X $679
P = $339.5
Therefore, the final price of the smart phone if you use the store credit card is $339.5
