To graph a function with two variables, you need to plot the points that satisfy the function in a coordinate system.
For example, suppose you have a function f(x,y) = x^2 + y^2. To graph this function, you can choose a set of values for x and y that satisfy the function, and plot these points in the coordinate system.
For example, if you choose x = 1 and y = 2, then the point (1,2) satisfies the function because f(1,2) = 1^2 + 2^2 = 1 + 4 = 5. Similarly, if you choose x = -2 and y = 3, then the point (-2,3) satisfies the function because f(-2,3) = (-2)^2 + 3^2 = 4 + 9 = 13.
You can repeat this process for a range of values for x and y to plot more points in the coordinate system. As you plot more points, you will start to see a pattern emerge, which is the graph of the function.
Note that the graph of a function with two independent variables will be a surface in three-dimensional space, rather than a curve in two-dimensional space like the graph of a function with only one variable.

luisa is building a sand box in her backyard. she places four pieces of wood in a rectangle to form the frame. the rectangle is 4 feet long and 3 feet wide. how can she use a measuring tape to make sure that the corners of the frame will be right angles?
Answer:
As we know rectangles have 90 degree angles at all 4 of its corners.
In this question we know that the length is 4 feet while the bredth is 3 feet.
Therefore to solve this answer we can use the Pythagoras theorm.
By Pythagoras:
[tex]4^{2} + 3^{2} = diagonal^{2}[/tex]
Therefore the diagonal must be 5 feet
So if Luisa measures the diagonal with a tape and it measures 5
Then it proves that all 4 corners due have 90 degree angles

Pls help! giving thanks. What is the slope of the line (picture above)
Answer:
[tex]slope = 1 [/tex]
Step-by-step explanation:
We can see that the graph cuts the x axis at , (-1,0) and y axis at (0,1) . So we can find the slope as ,
[tex]\implies slope = \dfrac{y_2-y_1}{x_2-x_1}\\\\\implies slope = \dfrac{ 1-0}{0+1} \\\\\implies\boxed{\boxed{ slope = 1 }}[/tex]

solve for x
2 + x^2 = 18
Answer:
16
Step-by-step explanation:
Answer:
4 and -4
Step-by-step explanation:
To solve, just isolate x
2+x^2=18
subtract both sides of the equation by 2
x^2=16
find the square root of 16
(remember, no matter if a number is positive or negative, if it is squared, it automatically becomes positive)
to get:
x=4
and
x= -4

Please help I’m confused on what to do.
The top left figure is similar with the figure given in this problem.
What are similar figures?Two figures are defined as similar triangles when they share these two features listed as follows:
Congruent angle measures, as both triangles have the same angle measures.Proportional side lengths, which helps us find the missing side lengths.Hence the top left figure is similar with the figure given in this problem, as:

Write this word sentence as an equation. 82 is the difference of a number b and 24
Answer:
106 - 24 = 82
Step-by-step explanation:
b = 106, solve 106 - 24 and you get 82.
Hope this helped.
Answer:
b/24=82
Step-by-step explanation:
Since the difference of an equation is the outcome of division we place 82 as the answer.
Also, since 82 is greater than 24 we can assume that the variable "b" is larger than both 82 and 24.

Matt decides the length of his table will be 15 in. He calculates that the area of the table is 30 in. squared. Determine if Matt’s calculation is correct
Answer:No Matt's calculation is not correct.
Step-by-step explanation:
We have to multiply by the number of the area.If it is 4 inches we multiply by 4
15 x 4 =60
A=4 inches squared
A=LxW (length x width )
so you can say that:
Matt is incorrect because He skipped the step of multiplying 2 by 2 in the formula which is where we get 4 from.
Use the information from the graphs to write the equation in y=ab*^x
Answer:
1). y = 4(1.75)ˣ
2). y = (2)ˣ
Step-by-step explanation:
1). Let the equation of the given exponential graph is,
y = a(b)ˣ
Graph of the given equation passes through two points (0, 4) and (0+1, 4+3)
For point (0, 4),
4 = a(b)⁰
a = 4
For point (1, 7),
7 = 4(b)¹
b = [tex]\frac{7}{4}[/tex]
b = 1.75
Therefore, equation of the function is,
y = 4(1.75)ˣ
2). Similarly, equation of the second graph will be same in the form of
y = a(b)ˣ
Second graph passes through the points (0, 1) and (2, 4)
For (0, 1),
1 = a(b)⁰
a = 1
For (2, 4),
4 = 1(b)²
b = 2
Therefore, exponential function representing the graph will be,
y = 1(2)ˣ
y = 2ˣ
whats the distributive property
Answer:
5n + 5a
Step-by-step explanation:
This would be your simplified algebra expression.
Answer:
The distributive property tells us how to solve equations in the form of a(b + c). The distributive property is sometimes called the distributive law of multiplication and division. Normally when we see an equation like this … 4(8+3) distributive property format 4(8+3) -> 4(11) -> 44 we just evaluate what’s in the parentheses first, then solve it: 4(8+3)=4x8 + 4x3=44 These are the 2 methods

Given
Scale is 1inch:9 feet
1 feet= 12 inch
The dividing board is 2 inches long
Suppose the actual length of the diving board is x
[tex]\therefore \dfrac{1}{9\times 12}=\dfrac{2}{x}\\\\\Rightarrow x=\dfrac{9\times 12\times 2}{1}\\\\\Rightarrow x=216\ inch\ \text{or}\ 18\ ft[/tex]
