Answer:
Equation: y = 2x
Graph: see attachment
Step-by-step explanation:
Pieces of paper = x
Number of Valentines = y
The equation is a proportional equation and can be represented as y = kx
k is the constant of proportionality
k = y/x
Using (2, 4),
k = 4/2 = 2
To find the equation, substitute k = 2 into y = kx
Thus:
y = 2x
The graph has been plotted and attached below.

Postulate/theorem = SAS postulate
Explanation :Given :
One side in both triangles are congruent. Another side in both triangles is also congruent. The angles between these two sides are also equal.Since 2 sides and an included angle is equal in these two triangle, they are said to be congruent under the SAS congruence postulate.
2nd pair of triangles :Postulate/theorem = ASA postulate
Explanation :Given :
In triangle KDS and triangle KWS :
Angle K = Angle KAngle S = Angle SSide KS = Side KSSince 2 angles and an included side is equal in these two triangles, they are said to be congruent under the ASA congruence postulate.
3rd pair of triangles :Postulate/theorem = AAS theorem
Explanation :Given :
In triangle ACB and triangle BED :
Angle A = Angle BAngle B = Angle DSide CB = Side EDSince two angles and one side is equal in these two triangles, they are said to be congruent under the AAS theorem.
How can we get system B for system A?
And
Are the systems equivalent?
Answer: Subtract the equations in system A.
=============================================================
Explanation:
The first equation of each system is the same, so we'll try to transform the second equation of system A into the second equation of system B.
There are probably a number of ways to do this, but the quickest way that I can see is to subtract the equations of each system.
For system A, notice how the x terms line up and subtract to 5x-4x = 1x = x. In that same system, we have the y terms subtract to y minus (-7y) = y-(-7y) = y+7y = 8y
So far we have x and 8y as the results. So the left side is x+8y, which matches with the x+8y in the second equation of system B. So far so good.
Now we subtract the values on the right hand sides of each equation of system A. We get 3-8 which turns into -5, which also matches with the -5 in the second equation of system B.
Overall, subtracting the two equations of system A leads to x+8y = -5, which is the second equation of system B.

A rectangular room is 14 feet by 20 feet. A rectangular rug is placed in the room so that a 2-foot border of floor around the edge of the room is not covered by the rug. What is the area of the rug?
Answer:
the rug should be 10 feet by 16 feet
this makes the area 160 foot squared
Step-by-step explanation:
there is a 2 foot border on each side so the total area loses 4 feet from length. this gives 10 feet by 16 feet.
160

After 24h will be 108p
Each c is 6m
12 laps
Step-by-step explanation:
36 - 33 = 3
33 - 30 = 3
30 - 27 = 3
27 - 3 = 24
12h = 36p
12h × 3 = 36h
So 36p need to × 3 too
36p × 3 108p
Because 3c to 5c, 18m to 30m need 12m. There was no 4c so the 12m need to divide two. 12m ÷ 2 = 6m.
So each c is 6.
72 ÷ 6 = 12
The six is from the last question.

how many triangles can be constucted measuring 60°, 60°, and 40°
Answer:
None, the sum of those angles does not equal 180 degrees
Answer:
none of the traingle can be constructedThe answer of this question is none. The sum of these three angles is 160°. So, none of the triangles can be constructed with angles measuring 60°, 60° and 40°
60°+60°+40°=160°The sum of three angles is 160°
so, none of the traingle can be constructed with angles measuring 60°,60°and 40°.

Select the procedure that can be used to show the converse of the Pythagorean theorem using side lengths chosen from 5 cm, 9 cm, 12 cm, and 15 cm
Answer:
Therefore the hypotenuse of the triangle is 15 cm and other two sides of the triangle are 9 cm and 12 cm and one angle of the triangle is 90°.
Step-by-step explanation:Pythagorean Theorem: According to this theorem the result obtained by squaring the value of the hypotenuse of a right angled triangle is equal to the sum of the squares of the values other two sides of the triangle.
Hypotenuse = h
Altitude = l
Base = b
l²+b²=h²
Here 6²=36
9²=81
12²=144
15²=225
From the above it is clear that
81+144=225
⇒9²+12²=15²
Therefore the hypotenuse of the triangle is 15 cm and other two sides of the triangle are 9 cm and 12 cm and one angle of the triangle is 90°.
Hope this helps!

I believe it's Therefore the hypotenuse of the triangle is 15 cm and other two sides of the triangle are 9 cm and 12 cm and one angle of the triangle is 90°. I'm not so sure sorry if it's incorrect

Given parallelogram FGHI determine the missing information
Don’t answer with one answer, blank or ridiculous answer please this is serious
Answer:
y = 3 cm and x = 2.5 cm
Step-by-step explanation:
As we can see it is a parallelogram so
y = 3 cm (being opposite sides of parallelogram)
Now while calculating the diagonal we can use the Pythagoras relation. i.e
perpendicular (p) = 4 cm (IH)
Base (b) = 3 cm (FI)
Hypotenuse (h) = FH = ?
We know by using Pythagoras theorem
h = √ p² + b²
= √ 4² + 3²
= √ 25
= 5 cm
Here we got FH = 5 cm
so the value of x will be 2.5 cm as the diagonal bisects.
Hope it will help :)

if £1 = 0.864 Lt, work out the amount, to the nearest penny , that 1 Lt is worth
Answer:
[tex]1\ Lt = \pounds 1.157[/tex]
Step-by-step explanation:
Given
[tex]\pounds 1 = 0.864\ Lt[/tex]
Required
Determine the worth of 1 Lt
[tex]\pounds 1 = 0.864\ Lt[/tex]
Divide both sides by 0.864
[tex]\pounds \frac{1}{0.864} = \frac{0.864}{0.864}\ Lt[/tex]
[tex]\pounds \frac{1}{0.864} = 1\ Lt[/tex]
[tex]1\ Lt = \pounds \frac{1}{0.864}[/tex]
[tex]1\ Lt = \pounds 1.157[/tex] -- approximated
