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!!

How many euros have the same value as 1 U.S. dollar?
How many U.S. dollars have the same value as 1 euro?
Answers
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

What is equation?The definition of an equation in algebra is a mathematical statement that proves two mathematical expressions are equal.
Types of Equations:
Linear Equation: More than one variable may be present in a linear equation. An equation is said to be linear if the maximum power of the variable is consistently 1. Quadratic Equation:This equation is of second order. At least one of the variables in a quadratic equation needs to be raised to exponent 2. Cubic Equation:A third-order equation is this one. At least one of the variables in cubic equations needs to be raised to exponent 3. Rational Equation: A fractional equation having a variable in the numerator, denominator, or both is referred to as a rational equation.let r be radius of cylindrical tank
h be height of tank

Answers
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.

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)

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?.
Answers
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.

Find the length of one side of the equilateral triangle.
Answers
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

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
