Answer:
A
Step-by-step explanation:
S = (n - 2)180 (divide by 180 on both sides)
[tex]\frac{S}{180}[/tex] = n - 2 ( add 2 on each side)
[tex]\frac{S}{180}[/tex] + 2 = n

Point A ( 5, 3) is reflected across the x-axis what is the coordinate of the image.
Answers
Answer:
(5, -3)
Step-by-step explanation:
when you reflect across x axis the y changes symbols.
The Point A(5, 3) is reflected across the x-axis, then the coordinate of the image is (5, -3).
What is a reflection?A reflection is a type of transformation that involves flipping a shape, known as the preimage, over a line, known as the line of reflection, to produce a new shape (called the image). You can picture what would happen if you flipped the form over the line in order to graph a reflection.
Given:
The point A(5, 3) is reflected across the x-axis.
The reflection across the x-axis:
The rule for a reflection over the x-axis is,
(x, y) → (x, −y).
So, the image point,
(5, 3) → (5, −3)
Therefore, the image point is (5, −3).

Determine if (2, 3) is a solution to the following equation
y = 5x - 1
Answers
3=5(2)-1
3=10-1
3=9
Therefore, 2,3 is not a solution because 3 is never equal to 9.
Answer:
No, it is not
Step-by-step explanation:
You have to plug it in:
(x,y) = (2,3)
y=5x-1 is also 3=5(2)-1
3=10-1
3=9 is a false statement so it is not a solution.

Answer:
CinnamonStep-by-step explanation:
From the given ingredient the recipe is meant for cinnamon-sugar cookies
Given the list
(Cinnamon, Baking Soda, Pure Vanilla Extract, Salt ,Cream of Tartar)
With me here is a typical recipe for the baking of cinnamon-sugar cookies
1 cup C&H® Golden Brown Sugar
½ cup C&H® Granulated Sugar
½ cup (1 stick) Unsalted butter, softened
1 teaspoon Pure vanilla extract
2 large eggs
2 ½ cups All-purpose flour
1 teaspoon Cream of tartar
½ teaspoon Baking soda
¼ teaspoon salt
2 tablespoons Granulated Sugar
2 teaspoons ground cinnamon
Now 6- 1/4tsp. corresponds to 6(0.25)=1.5tsp
1.5tsp is a close approximation of 2 teaspoons Ground cinnamon in our typical recipe, hence we could predict that Thea added Cinnamon last

For 6z=126, Chris wrote that z=756. Explain what Mike’s mistake was. Then tell the correct answer.
Answers
Step-by-step explanation:
6z=126
z = 126 ÷ 6 = 21
Chris's
z = 756
6z= 126
z = 126 × 6 = 756
correct answer = 21
the number 6 is being multiplied with z.So if the number 6 is going to the right side it will divide the number on the right side.
but for chris he multiplied the number on the right side with 6.So that is the mistake.
