Step-by-step explanation:
Given the system of equations,
[tex]y=2x-3\\y=-x+3[/tex]
We can substitute one equations into another since both equations solve for y. I will use the second equation for this example.
Step 1: Substitute
[tex]-x+3=2x-3[/tex]
Step 2: Simplify
[tex]6=3x\\x=2[/tex]
Now, we can easily substitute our x value into one of the equations.
Step 3: Substitute.. again
[tex]y=-2+3\\y=1[/tex]
Solution: [tex](2,1)[/tex]

Transformations with quadratic equations (shift left, right, up, down, reflections, etc.), how to find the axis of symmetry and vertex by the equation, how to find domain and range from a graph, telling if its a quadratic equation by 1st and 2nd difference and anything else related. Also please help me because when creating tables with the equation, the negatives I struggle with for example: y=x^2-4x-6 and substituting -2 it gets super confusing. I WOULD GIVE OUT MORE POINTS but sometimes ppl put bad responses SO PLEASE HELP ME CORRECTLY!! THANK YOU SO MUCH!

Quadratic equations are polynomial equations of degree 2. They can be written in the form ax² + bx + c = 0, where a, b, and c are constants. The graph of a quadratic equation is a parabola.
Transformations involve shifting or reflecting the graph of a quadratic equation. The most common transformations are shifting the graph left or right (by adding or subtracting a constant from x), shifting the graph up or down (by adding or subtracting a constant from y), and reflecting the graph across the x-axis or y-axis.
How to explain the mathematical termsThe axis of symmetry is a vertical line that divides the parabola into two symmetrical halves. The equation of the axis of symmetry for a quadratic equation of the form y = ax² + bx + c is x = -b/2a.
The vertex is the point on the parabola where it reaches its maximum or minimum value. The vertex of a quadratic equation of the form y = ax^2 + bx + c is (-b/2a, c - b²/4a).
The domain of a quadratic equation is the set of all real numbers for which the equation is defined. The range is the set of all possible y-values that the equation can take. You can find the domain and range of a quadratic equation by looking at its graph.
In recognizing quadratic equations, you can tell if an equation is quadratic by looking at the powers of the variables. A quadratic equation will always have a variable raised to the power of 2.
When substituting negative numbers into a quadratic equation, it can be helpful to use parentheses to avoid confusion. For example, to evaluate y = x² - 4x - 6 at x = -2, you would write y = (-2)² - 4(-2) - 6 = 16 + 8 - 6 = 18.

THANK YOU GUYS SO MUCH!!! <333333

Thus when angle m is 34° and angle n is (2x)° when angle m and angle n are supplementary,
angle m + angle n = 180°
34° + (2x)° = 180°
*minus 34° on both sides of the eqn*
(2x)° = 180°-34°
(2x)° = 146°
To find x, divide both sides of the eqn by 2
x= 146°/2
x= 73°
I hope this helps! Feel free to clarify if you have any questions!
The value of x is:
↬ 73Solution:
If two angles are supplementary, that means that the sum of their measures is 180°.
We're given 2 angles:
[tex]\sf{\angle m}[/tex][tex]\sf{\angle n}[/tex]And since they're supplementary, the following holds true:
[tex]\sf{\angle m + \angle n = 180}[/tex]
Next, we know that [tex]\sf{\angle m=34}[/tex], so we plug that in
[tex]\sf{34+\angle n = 180}[/tex]
Then, ∠n = 2x:
[tex]\sf{34+2x=180}[/tex]
Which is the same as
[tex]\sf{2x+34=180}[/tex]
Subtract 34 from each side
[tex]\sf{2x=146}[/tex]
Divide each side by 2
[tex]\sf{x=73}[/tex]
Hence, x = 73help me pls. i dont get it
