Different equations can result in identical graphs. For example, −=0
y−x=0
and (−)(2+2)=0
(y−x)(x2+y2)=0
both have the same graph on the real xy-plane, a diagonal line through the origin. The first equation is a linear equation while the second is a cubic equation.
Step-by-step explanation:
To compare two equations or to find the solution of two equation we represent two different equations on the same graph.
We need to explain why it is possible that one graph could represent two different equations.
What is the graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points. A graph consists of some points and lines between them. The length of the lines and position of the points do not matter.
On the same graph we can represent two different equations, to compare two equations or to find the solution of two equation.
Therefore, to compare two equations or to find the solution of two equation we represent two different equations on the same graph.

. Orlando needs to fix windows in his house. He must buy 3 feets of wood,
which costs $7 per foot. He also needs to buy 4 pieces of glass. Each piece of
glass costs $23. What will be the total cost for fixing the windows
What equation could you use to calculate the total cos
Answer:(7x3)+(4x24)=117
Step-by-step explanation:
Since he needs 3 feet of wood and it is 7 dollar per foot, you need to multiply 7 by 3. Since he needs 4 pieces of glass and its 24 dollars per glass multiply 4 by 24. Add the products. Ur done!

Let f(x) = (x and g(x) = 5V x . Find (f -g)(x).
Answer:
1/6
Step-by-step explanation:
Given the function
f(x)=x^3+x^2+x
Get the inverse. Let y = f(x)
y = x^3+x^2+x
Replace y with x
x = y³+y²+y
Differentiate with respect to x
1 =3y²dy/dx + 2ydy/dx + dy/dx
1 = (3y²+2y+1)dy/dx
dy/dx = 1/3y²+2y+1
g'(x) = 1/3(g(x))²+2g(x)+1
If x = 3
g'(3) = 1/3(g(3))²+2g(3)+1
g'(3) =1/3(1)²+2(1)+1
g'(3) = 1/3+2+1
g'(3) = 1/6
Hence g'(3) = 1/6

I need to write it in standard form
Answer:
Step-by-step explanation:
[tex]Slope=\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\=\dfrac{-6-9}{2-4}=\dfrac{-15}{-2}=\dfrac{15}{2}\\\\[/tex]
Equation:
[tex]y -y_{1}=m(x -x{1})\\\\y - 9 = \dfrac{15}{2}(x-4)\\Multiply \ the \ entire \ equation \ by 2\\\\2*(y -9)=2*\dfrac{15}{2}(x-4)[/tex]
2y - 2*9 = 15(x - 4)
2y - 18 = 15x - 60
2y - 18 + 60 = 15x
2y + 42 = 15x
15x - 2y = 42

since we know on straight line 180° is formedthen➡90° +(x+x+x)= 180°
➡90° + 3x = 180°
➡3x= 180°-90°
➡3x= 90°
➡x = 90°/3= 30°
➡x= 30°then in triangle sum of all angles = 180°➡90°+x+y = 180°
➡90°+ 30° +y = 180°
➡120+y = 180°
➡y= 180°-120°
y = 60now to find y-x = 60°-30°=30➡30 is correct answer

the book fair had a sale where 6 books were 20.46 If you wanted to buy 7 books how much money would need
Answer:
20.46 divided by 6 = 3.41
3.41 times 7 = 23.87
Step-by-step explanation:
Answer:
$23.87
Step-by-step explanation:
We can start by figuring out how much one book costs. To do this we divide 20.46 by 6.
20.46/6=3.41
Each book costs 3.41
Since we bought 7 books we multiply 3.41 by 7
3.41*7=$23.87

A student estimated a mass of 250grams, according to the scale the mass is actually 240grams. What is the percent error? (round to tenths place
Answer:
4.2%
Step-by-step explanation:
percent error = (estimated value - actual value)/(actual value) × 100%
Here, the estimated value is 250 g, and the actual value is 250 g.
percent error = (estimated value - actual value)/(actual value) × 100%
percent error = (250 g - 240 g)/(240 g) × 100%
percent error = 10/240 × 100%
percent error = 0.041666... × 100%
percent error = 4.2%
Step-by-step explanation:
the real thing is 240 grams.
the estimation of 250 grams was 10 grams off.
how many % is that ?
for that we need to divide these 10 by 1%.
and 1% is 240/100 = 2.4 grams.
10 / 2.4 = 4.166666666... ≈ 4.2%
the percent error is 4.2%
