Answer:
so you graph at (0,2), and go up one, over two for every other point you graph.
Step-by-step explanation:
rise over run.
basically, the m is the slope, and b is the y intercept (where it intersects the y axis).
so when looking at how to graph the line based on 1/2 or any other number, I use rise/run, which is basically telling us tha we need to go up one and over 2 (1/2)
if that makes any sense, let me know if you have any further questions. you got this, youre doing your best!!

Which is true regarding Armando’s use of algebra tiles? He used the algebra tiles correctly. He did not represent the two original factors correctly. The signs on some of the products are incorrect. Some of the products do not show the correct powers of x.
The correct statement about Armando’s use of algebra tiles is some of the products do not show the correct powers of x.
Given
Armando used algebra tiles to represent the product 3x (2x -1 ).
ProductThe number or expression results from the multiplication together of two or more numbers or expressions.
The correct way to find the product function is;
[tex]\rm = 3x (2x -1 )\\\\=3x \times 2x - 3x\times 1\\\\= 6x^2-3x[/tex]
Hence, the correct statement about Armando’s use of algebra tiles is some of the products do not show the correct powers of x.

Step-by-step explanation:
2 x 1 +2 = 4 mhm yes mk ok ~
OKURRRRRRRRRRRRRRRRR
Answer:
d=1
Step-by-step explanation:
You first need to isolate the variable, d. To do this, you move everything away from it, using the opposite order of operations for each variable. First, you need to subtract 2 on both sides which gives you 2d=2, then you divide 2 from 2d and divide it with the single 2 and get 1. Hope that helps :)

Find the length of one side of the equilateral triangle.
Answer:
side = 20 cm
Step-by-step explanation:
Since the triangle is equilateral then the 3 sides are congruent.
Equate the 2 given sides and solve for x
5(x - 3) = 2x + 6
5x - 15 = 2x + 6 ( subtract 2x from both sides )
3x - 15 = 6 ( add 15 to both sides )
3x = 21 ( divide both sides by 3 )
x = 7
then length of side is
2x + 6 = 2(7) + 6 = 14 + 6 = 20 cm
Answer:
20 cm
Step-by-step explanation:
Properties of an Equilateral Triangle
Regular polygon with 3 sidesSides lengths are equalInterior angles are equalGiven information
length of one side: (2x + 6) cmlength of second side: 5(x - 3) cmFind value of x
As side lengths are equal, equate the expressions and solve for x.
2x + 6 = 5(x - 3)
⇒ 2x + 6 = 5x - 15
⇒ 2x + 6 + 15 = 5x - 15 + 15
⇒ 2x + 21 = 5x
⇒ 2x + 21 - 2x = 5x - 2x
⇒ 21 = 3x
⇒ 21 ÷ 3 = 3x ÷ 3
⇒ 7 = x
⇒ x = 7
Side lengths
Substitute x = 7 into one of the given expressions.
⇒ length of one side: 2(7) + 6 = 20 cm

Marina can bicycle 19. 5 miles in the same time it takes her to run 6 miles. She bikes 9 miles per hour faster than she runs. At what speed does Marina run?.
Speed is the rate at which a body changes its position. The speed by which Marina runs is 4 miles/ hr.
What is Speed?Speed is the rate at which a body changes its position. It is given by the formula,
[tex]\rm{Speed = \dfrac{Distance}{Time}[/tex]
Given to us
Marina can bicycle 19. 5 miles at the same time it takes her to run 6 miles.
Marina bikes 9 miles per hour faster than she runs.
Let the speed of the Marina running be s, and the time is taken to run 6 miles be t.
Time is taken by Marina to cover a distance of 6 miles by running,
[tex]\rm t = \dfrac{6\ miles}{s}[/tex]
Since the speed of Marina's bicycle is 9 miles per hour faster than she runs. Time is taken by Marina to cover a distance of 19. 5 miles by bicycle,
[tex]\rm t = \dfrac{19.5\ miles}{s+9}[/tex]
We know that Marina can bicycle 19. 5 miles at the same time it takes her to run 6 miles. therefore,
[tex]\rm t = \dfrac{6\ miles}{s}= \dfrac{19.5\ miles}{s+9}[/tex]
[tex]\dfrac{6}{s}= \dfrac{19.5}{s+9}[/tex]
Solving the given equation we will get,
[tex]\rm s = 4\ miles/hr[/tex]
Hence, the speed by which Marina runs is 4 miles/ hr.

Rohan draws a circle of radius 10 cm with the help of compass and scale. He also draws two chords, AB and CD in such a way that AB and CD are 6 cm and 8 cm from the centre O. Now, he has some doubts that are given below. Help him out by answering these questions:
It can be deduced that the chord of AB will be 16 cm and the chord of CD will be 12 cm.
How to calculate the chordFrom the information given, we will use Pythagoras theorem to find half of AB. This will be:
= ✓10² - ✓6²
= ✓64
= 8.
Therefore, AB = 8 × 2 = 16cm
The length of CD will be:

Hi there!
Parabola x² = 12y
→ x² = 4ay
→ 4a = 12
→ a = 12÷4
→ a = 3
So, the co-ordinates of the focus is:-
S(0,a)=(0,3)
→ Let AB be the latus rectum of the given parabola.
→ Coordinates of end-points of latus rectum are (-2a,a), (2a,a)
→ Coordinates of A are (-6,3), while B's coordinates are (6,3).
→ ∆OAB are O(0,0), A(-6,3), B(6,3)
Area of ∆OAB is :-
(Solving part attached as image)
=> 18 unit² is the required answer.
Answer:
18 sq. unit
Step-by-step explanation:
Parabola is x²=12y
On comparing it with
→x²=4ay
→4a=12
→a=12/4
→a=3
Finding the value of x.
→x²=12y
→x²=12×3
→x²=36
→x=√36
→x=6
When we have a=3 and x=6
(-x1,a)=(-6,3)
(x1,a)=(6,3)
Let,
(x1,y1)=(0,0)
(x2,y2)=(6,3)
(x3,y3)(-6,3)
Now,
Area=[tex]=\frac{1}{2} *b*h\\\\=\frac{1}{2} [x1(y2-y3)+x2(y3-y1)+x3(y1-y2)\\\\=\frac{1}{2} [0(3-3)+6(3-0)+(-6)(0-3)\\\\=\frac{1}{2} [18+18]\\\\\\=18.sq.units[/tex]
We can calculate E, the amount of euros that has the same value as D.S. dollars, using the equation E= 17/20 D.
How many euros have the same value as 1 U.S. dollar?
How many U.S. dollars have the same value as 1 euro?
Answer:
0.85
1.176
Step-by-step explanation:
E = 17/20 D
Let D = 1,
E = 17/20 × 1
E = 17/20 = 0.85
1 dollar = 0.85 Euro
E = 17/20 D
17/20 D = E
D = 20/17 E
Let E = 1,
D = 20/17 × 1
D = 1.176
1 Euro = 1.176 dollar

Find the value of x. x°+65°+109°+136°=310°
(if you can, please show how you got the answer. :D)
Answer:
x=0
Step-by-step explanation:
x°+65°+109°+136°=310°
we know that this whole equation equals 310.
so we add all the numbers equaling x+174+136=310 : x+310=310
x clearly equals 0 and even then you can subtract 310 from both sides which still gives you 0.
hopefully this helps.
Heya!
Answer:
x° = 0°
Step-by-step explanation:
x°+ 65° + 109° + 136° = 310°
Add all of the degrees on the left side together.
x° + 310° = 310°
Subtract 310° from both sides.
x° + 310° = 310°
- 310° - 310°
+ 310° and - 310° cancel out. 310° - 310° is 0.
x° = 0°
So, x° = 310° is your answer.
