Linear equations with two unknowns
Enter an equation or problem
x+4y=0;16y−4x
We think you wrote
x+4y=0;16y-4x
This solution deals with linear equations with two unknowns.
Solution found
{x,y}={0,0}
See steps
Step by Step Solution
System of Linear Equations entered :
[1] x+4y=0
[2] 16y-4x
Equations Simplified or Rearranged :
[1] x + 4y = 0
[2] -4x + 16y = 0
Graphic Representation of the Equations :
4y + x = 0 16y - 4x = 0
Solve by Substitution :
// Solve equation [1] for the variable x
[1] x = -4y
// Plug this in for variable x in equation [2]
[2] -4•(-4y) + 16y = 0
[2] 32y = 0
// Solve equation [2] for the variable y
[2] 32y = 0
[2] y = 0
// By now we know this much :
x = -4y
y = 0
// Use the y value to solve for x
x = -4(-0/32766) = 0
Solution :
{x,y} = {0,0/32766}

A furniture company created an L-shaped table by removing part of a square table.
a. Write an expression that represents the area of the L-shaped table.
b. What are all the side lengths of the L-shaped table?
c. The furniture company decides to create another table with the same area, but needs this table to be rectangular. What are the possible dimensions of the rectangular table? Explain.
Answer:
Step-by-step explanation:
(a) Identity: [tex](a-b)^{2}[/tex] = [tex]a^2 - 2ab + b^2[/tex]
Here, [tex](a-b)^2[/tex] represents the perimeter of room.
a = 10p
b= n
∴ area of l-shaped table room = [tex](10p-n)^2[/tex]
[tex](10p-n)^2 = (10p)^2 - 2(10p)(n) + n^2[/tex]
I will think about (b) and (c) part. Hope this much helps.

The table here shows the land area in square miles of the five largest cities in the U.S. How much greater is the area of Juneau than the area of the next largest city?
Answer:
B.) 1020 mi ^2
Since the next largest city is Anchorage, Alaska you would just subtract Juneau's land area from Anchorage's land area.
2717 - 1697

Find the m∠1 and m∠2
Answer:
m<1=31 degrees and m<2=106 degrees
Step-by-step explanation:
To find m<1 you have to do m<2 first. Use the 74 degrees from m<4 and subtract that from 180. 180-74=106. With that information you can find m<1. Take 106 from m<2 and 43 from m<3 and subtract that from 180. 180-106-43=31.
Answer:
m<1=31 & m<2=106

9/10 x+4/5=28.3
choices:
x=133/5
x=275/9
x=97/3
explain why
Answer:
275/9
Step-by-step explanation:
9/10x + 4/5 = 28.3
leave out the decimal sign in 28.3 and then turn it into a fraction.
9/10x + 4/5 = 283/10
Multiply them by 10
9/10x • 10 = 9x
4/5 • 10 = 8
283/10 • 10 = 283
9x + 8 = 283
Separate the x from the non x
9x = 283 - 8
= 275
9x = 275
275/9 = x
The solution to the equation 9/10 x+4/5=28.3 is x = 275/9, Option B is correct.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given equation is 9/10 x+4/5=28.3
Nine by ten times of x plus four by five equal to twenty eight point three
x is the variable in the equation
We have to solve for x
Subtract 4/5 from both sides
9/10x = 28.3 - 4/5
9/10x= 28.3 -0.8
9/10x=27.5
9x=27.5×10
9x=275
Divide both sides by 9
x=275/9
Hence, the solution to the equation 9/10 x+4/5=28.3 is x = 275/9, Option B is correct.

Consider the following points on the graphs of y = sin(x) and y = sin(2x), with the added vertical dashed lines:
What are c and d?
Recall that [tex]\sin 2x=2\sin x \cos x[/tex].
If [tex]\sin a=-4/5[/tex], then [tex]\cos a=-3/5[/tex].
[tex]c=\sin(2a)=2(-4/5)(-3/5)=24/25[/tex]
Using similar logic, [tex]d=120/169[/tex].
The value of the variables are,
c = - 24/25 and d = 120/169
From the given graph we can see that two functions,
y = sin (x) and y = sin (2x)
Now, (a, -4/5) lies on y = sin x so,
sin (a) = - 4/5
cos (a) = √(1 - sin² (a)) = √[1 - 16/25] = √9/25 = 3/5 [since cosine function is positive in between - π and 0]
Again (a, c) lies on the y = sin 2x so,
c = sin (2a) = 2 sin (a) cos (a) = 2 (-4/5) (3/5) = - 24/25
Further,
(b, 5/13) lies on y = sin x so,
sin b = 5/13
cos b = √(1 - sin² (a)) = √[1 - 25/169] = √144/169 = 12/13 [since cosine function is positive in between 0 and π/2]
Again, (b, d) lies on y = sin (2x) so,
d = sin 2b = 2 sin (b) cos (b) = 2 (5/13) (12/13) = 120/169

Please help! please write a multiplication equation that shows how the denominators 3 and 4 are related to 12.
Answer:
assuming the value x = 1/3 and y = 1/4
so if you use both value in an addition equation, you'll get this equation :
[tex] \frac{1}{3} + \frac{1}{4} [/tex]
which then you can simplify by making both fraction have the same value :
[tex] \frac{1}{3} \times \frac{4}{4} + \frac{1}{4} \times \frac{3}{3} [/tex]
[tex] \frac{4}{12} + \frac{3}{12} [/tex]
therefore you get the answer :
[tex] \frac{7}{12} [/tex]
So this equation shows that the denominator 3 and 4 are related to 12.
The denominators 3 and 4 are related to 12 in a multiplication equation, you can express it as 1/3 * 1/4 = 1/12
The denominators 3 and 4 are related to 12 in a multiplication equation, you can express it as:
1/3 * 1/4 = 1/12
In this equation, the product of 3 and 4 (which is 12) represents how the denominators 3 and 4 combine to give the common denominator of 12. In fractions, when you need to find a common denominator to add or subtract fractions with different denominators, you can use this multiplication relationship. For example, if you have fractions with denominators 3 and 4, you can convert them to fractions with a common denominator of 12 by multiplying both the numerator and the denominator of each fraction by the appropriate factor to get:
1/3 = (1 * 4) / (3 * 4) = 4/12
1/4 = (1 * 3) / (4 * 3) = 3/12
Now both fractions have a common denominator of 12, and you can easily add or subtract them.

A basket contains only apples and oranges, and the ratio of apples to oranges is 9:7. If there are 128 pieces of fruit in he basket, how many are oranges?
Answer:
There are 56 oranges in the basket, since the ratio of apples to oranges is 9:7. To calculate this, you can use the proportion method. First, set up a proportion using the ratio of apples to oranges (9:7):
9/7 = x/128
Then, solve for x.
x = (9/7) * 128
x = 112
Answer:
72 and 56
Step-by-step explanation:
Ratio of apples in the basket = 9x
Ratio of oranges in the basket = 7x
Total fruits in the basket = 128
So, Apples + Oranges = Total fruit
9x + 7x = 128
16x = 128
x = 128 ÷ 16
x = 8
∴ So, number of apples = 9x --> 9*8 = 72 apples
number of oranges = 7x --> 7*8 = 56 oranges

Jada’s babysitter is times Jada’s current age. In 5 years, Jada will be her
babysitter’s current age.
How many years old is Jada now?
Answer:
5 years old.
Step-by-step explanation:
Let's call Jada's current age "J" and the babysitter's current age "B".
From the information given, we know:
B = J (Jada's babysitter is J times Jada's current age)
J + 5 = B (In 5 years, Jada will be her babysitter's current age)
By substituting the first equation into the second equation:
J + 5 = J
5 = J
Therefore, Jada is currently 5 years old.
