y = 3x +2
y = 3x - 3
These lines are..
A.Perpendicular
B.Neither
C.The same line
D.Parallel
Answer:
Neither
Step-by-step explanation:
To determine if two lines are parallel or perpendicular, you have to look at the slopes. For the line y=kx+b, k is the slope.
For two lines y=k1x+b1 and y=k2X+b2 ,When K1=K2, two lines are parallel; when K1=-1/k2, two lines are perpendicular. It doesn't matter whatever b1, b2 are. Hence to save time, you only need to calculate k1 and k2.
To calculate the slope k of any line, you have to change the equation to y=kx+b
For -y=3x-2, k=3/(-1)=-3 (you divide -1 on each side of =, but you don't need to calculate -2/(-1))
For -6X+2y=6, K=6/2=3 (you first move the -6x to right side, it becomes 6x, then divide by 2)
Now you can get the answer: The two lines neither parallel nor perpendicular
Answer:
D. Parallel

Answer:
As time increases, grams decrease
To describe the relationship between the two quantities, we first have to identify what those two quantities are.
Well, it says it right on the graph.
Our two quantities are time (the x value) and grams (the y value)
So, what is the relationship between the two quantities?
Well, let's first look at what each one is doing.
Well, time is increasing
Grams, however, are decreasing
So, the relationship is as follows:

If a line goes through points (-2, 9) and (0, 3), what is its slope?
a. -1/3
b. -3
c. 3
d. 6
Answer:
b. -3
Step-by-step explanation:
slope = y2 - y1 / x2 - x1
= 3 - 9 / 0 + 2
= -6 / 2
= -3
Answer:
b
Step-by-step explanation:
calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 2, 9 ) and (x₂, y₂ ) = (0, 3 )

$4000 is divided between three children in the ratio 2:3:5.
How much does each child receive?
Okay so here is how it works:
Because 2:3:5 is the ratio 10 is the total because 2+3+5 is 10 right?
You therefore equate 10 to 4000
10=4000
so if 10 is equal to 4000 what about 2,3 or 5?
2/10×4000=800
3/10×4000=1200
5/10×4000=2000

A radio station is giving away a total of Rs 124,000 in August on promotion. If they increase the amount given away each day by Rs 100.
(i) How much should they give away the first day?
(ii) How much have they give away on the 15th day ?
On the first day the company is giving Rs124, 000.
On the fifteenth day the company will give Rs 125400
The amount they wanted to give in august for promotion is Rs 124,000. They increased the amount each day by Rs 100.
Therefore, the sequence will be as follows;
124,000, 124,100, 124,200 .......
i.
The amount they will give on the first day is Rs124, 000
Arithmetic progression formulaaₙ = a + (n - 1)dii
The sequence is increasing by 100. Therefore,
common difference = 100
first term = 124, 000
Therefore,
a₁₅ = 124000 + (15 - 1)100
a₁₅ = 124000 + 1400
a₁₅ = 125400

Who was alan turing and what were his contributions to the field of mathematics?.
Answer:
Alan Mathison Turing OBE FRS was an English mathematician, computer scientist, logician, cryptanalyst, philosopher, and theoretical biologist.
Born: June 23, 1912, Maida Vale, London, United Kingdom
Died: June 7, 1954, Wilmslow, United Kingdom
Turing's main contribution to mathematics, however, was his work on computation theory. Presaging the invention of the modern computer, Turing designed an abstract computing device known as the Turing machine — an entirely virtual construct which could perform calculations and follow instructions.
(87 POINTS I NEED ANSWER TODAY!!!) A right trapezoidal prism is sliced parallel to its base.
What is the shape of the resulting two-dimensional cross section?
trapezoid
parallelogram
rectangle
square
Answer:
trapezoid
Step-by-step explanation:
A right trapezoid has 2 parallel sides and 2 adjacent right angles.
In geometry, the base of a prism is the actual shape.
So the base of a triangular prism is the triangle, similarly the base of a pentagonal prism is the pentagon, etc.
Therefore, the base of a trapezoidal prism is the trapezoid itself.
If the prism is cut parallel to the base, then the cross section will be the same shape as the base. So in this case, it will be a trapezoid.

The measure of angle x from the diagram is 102 degrees
Lines and anglesFrom the given diagram, we can see that the measure of angle "x" lies on the same line with 39 degrees. Since the sum of angles on a straight line is 180 degrees, hence;
39 + x + 39 = 180
78 + x = 180
Subtract 78 from both sides
78 + x - 78 = 180 - 78
x = 180 - 78
x = 102 degrees
Hence the measure of angle x from the diagram is 102 degrees

Lynn was shopping and found a purse that was marked with a discount of [tex]\frac{1}{3}[/tex]off.” If the original cost of the purse was $80 , how much will Lynn pay?
Answer:
[tex] \frac{160}{3} [/tex]
Step-by-step explanation:
Step 1: A discount of
[tex] \frac{1}{3} [/tex]
means that the current price is two thirds of the original cost.
Step 2: The total cost is
[tex]80 \times \frac{2}{3} = \frac{160}{3} [/tex]
and the answer follows.
Solution:
Note that:
80 x (3/3 - 1/3) = Discounted costSimplify the expression.
80 x (3/3 - 1/3)=> 80 x (2/3)=> 160/3 = $53.33 = Discounted costLynn will pay $53.33.

A trapezoid has an area of 234.06 square feet. One base is 19.2 feet long. The other base is
9 feet long. What is the height?
Answer: Height = 16.6 ft
Step-by-step explanation:
The area of a trapezoid is (b1+b2)*h/2, where b1 and b2 are the bases and h is the height.
We can plug in the values given:
234.06 ft^2 = (19.2 ft + 9 ft)*h/2
We can multiply both sides by 2 and combine like terms:
468.12 ft^2 = 28.2 ft*h
Divide both sides by 28.2 ft:
Height = 16.6 ft
Find the measure of each angle
m∠A =
m∠B =
m∠BCA =
Before we solve for each angle, let's find the bottom left angle of the triangle.
We know that:
Straight line = 106 + xStraight line = 180This means that:
⇒ 106 + x = 180Step-by step calculations:
⇒ 106 + x = 180
⇒ 106 - 106 + x = 180 - 106
⇒ x = ∠BCA = 74°
Solving for y:We know that:
⇒ Sum of the interior angles of the triangle: 180°
This means that:
⇒ (74) + (3y + 22) + (4y) = 180
Step-by step calculations:
⇒ (74) + (3y + 22) + (4y) = 180
⇒ 96 + 7y = 180
⇒ 96 - 96 + 7y = 180 - 96
⇒ 7y = 84
⇒ 7y/7 = 84/7
⇒ y = 12
Finding the measure of each angle:Step-by step calculations:
⇒ ∠B = 3y + 22
⇒ ∠B = 3(12) + 22
⇒ ∠B = 36 + 22
⇒ ∠B = 58°
-------------------------------------
⇒ ∠A = 4y
⇒ ∠A = 4(12)
⇒ ∠A = 48°
