Step-by-step explanation: Well, it’s asking you to write an equation for it in Y=MX+B format. That would be something like y=4x+2 (not the answer.) There are 4 different points on here. A, b, c, and d. There is an incomplete equation, 2x+1. There is also a degree, 33. This shape that these lines formed also have a 90 degree angle, as you can see next to the B. It’s pretty much 3 angles out together. Find the degrees for the two other angles, after you do that, use a formula like this, 1+2, then subtract the answer from 180 degrees. If the number turned out negative, then subtract 180 from the answer instead. That will get you far enough to actually form the equation.

I have a math test tomorrow about Quadratics and Translations. Can somebody give me an easy-to-understand summary of these key topics?
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!

Answers

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 terms

The 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.

Quadrilateral A'B′C′D′ is the result of dilating quadrilateral ABCD about point P by a scale factor of 2.

Answers

Answer:

Line CD and C'D' are both perpendicular to the x-axis.

The dilated quadrilateral A'B'C'D' is created by enlarging quadrilateral ABCD about point P using a scale factor of 2. The lengths of the sides are multiplied by 2, while the angles remain the same.

The dilated quadrilateral A'B'C'D' is formed by enlarging quadrilateral ABCD about point P using a scale factor of 2.

To understand the concept, let's break it down step-by-step: 1. A dilation is a transformation that changes the size of a figure while keeping its shape intact.

2. In this case, the original quadrilateral ABCD is being dilated, resulting in a new quadrilateral A'B'C'D'.

3. The point P serves as the center of dilation, around which the quadrilateral is enlarged or reduced.

4. The scale factor of 2 means that the lengths of the sides of the original quadrilateral are multiplied by 2 to obtain the lengths of the sides of the dilated quadrilateral.

5. For example, if side AB has a length of 5 units in ABCD, then side A'B' will have a length of 10 units in A'B'C'D' since 5 multiplied by 2 is 10.

6. Similarly, all other sides of the dilated quadrilateral will be twice the length of the corresponding sides in the original quadrilateral.

7. The angles of the quadrilateral will remain the same, as dilations only affect the lengths of the sides, not the angles. 8.

The resulting dilated quadrilateral will be similar to the original quadrilateral, meaning that the corresponding angles will be equal, and the corresponding sides will be proportional.

So, in summary, the dilated quadrilateral A'B'C'D' is created by enlarging quadrilateral ABCD about point P using a scale factor of 2. The lengths of the sides are multiplied by 2, while the angles remain the same.

How many degrees is angle 7?

Answers

Answer:

42°

Step-by-step explanation:

This is defined as a transversal in geometry, where one line intersects two straight lines.

It is given that one of the angles is 42°. Let the angle that measure 42° be denoted as ∠42.

∠4 ≅ ∠42 based on the alternate interior angles theorem.

∠4 ≅ ∠7 based on the vertical angles theorem.

Therefore, ∠42 ≅ ∠7 based on CPCTC.

Therefore,

m∠7 = 42°.
