Is (2,4) a solution of the equation y=x-2
Answers
4 = 0
Is it a solution for y = x - 2?
No.
Final answer:
To determine if a point is a solution to an equation, substitute the values of the coordinates into the equation. The point (2,4) was found to not be a solution to the equation y=x-2.
Explanation:
To test if the point (2,4) is a solution to the equation y=x-2, we replace the 'x' with '2' and 'y' with '4' in the equation.
So if y is indeed equal to x - 2, then, replacing x and y should leave you with a true statement. That will be 4 = 2 - 2. But this results in, 4 = 0 which is not true.
So, (2,4) is not a solution to the equation y=x-2.

is it in a single term
Final answer:
The expression 5x + 2x simplifies into 7x. Substituting the values 1, 2, 3, 4, and 5 for x in both expressions yields the results 7, 14, 21, 28, and 35 for 5x + 2x, and 6, 13, 20, 27, and 34 for 7x - 1.
Explanation:
The expression 5x + 2x can be simplified into a single term by adding the coefficients of similar terms. This means you add the 5 and 2 together. The result is 7x.
For substituting different values into the expressions 5x + 2x and 7x - 1, let's use 1, 2, 3, 4, and 5 as the values for x.
- For x=1: 5(1) + 2(1) = 7 and 7(1)-1 = 6
- For x=2: 5(2) + 2(2) = 14 and 7(2)-1 = 13
- For x=3: 5(3) + 2(3) = 21 and 7(3)-1 = 20
- For x=4: 5(4) + 2(4) = 28 and 7(4)-1 = 27
- For x=5: 5(5) + 2(5) = 35 and 7(5)-1 = 34

Hi Brainiac
y=2x-3
y= 2x+5
Ok we need to solve y=2x-3 for y
Now substitute 2x-3 for y in y=2x+5
y=2x+5
2x-3=2x+5
Add -2x
2x-3-2x=2x+5-2x
-3=5
Add 3

The area of polygon is 18 sq. units.
What is polygon?
In geometry, a polygon is any closed curve made up of a collection of continuous line segments, without any intersections. Triangles (three sides), quadrilaterals (four sides), and pentagons.
Given that jack has a model f(x) = x² + 2x +3
where f(x) is area of polygon and x shows length of side
area when length is 3
substitute value of x in equation
f(x) = x² + 2x +3
f(3) = 3² + 2ₓ3 + 3
f(3) = 9 + 6+ 3
f(3) = 18
Hence area of polygon according to given equation is 18 sq. units
