Determine if (2, 3) is a solution to the following equation
y = 5x - 1

Answers

y=5x-1
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.

The table represents a linear equation.

A two column table with 5 rows. The first column, x, has the entries, negative 10, negative 5, 10, 15. The second column, y, has the entries, 8, 7. 4, 3.
Which equation shows how (–10, 8) can be used to write the equation of this line in point-slope form?

y – 8 = –0.15(x – 10)
y + 8 = –0.15(x – 10)
y – 8 = –0.2(x + 10)

Sonya is a waitress. She earns $200 per week plus a 15% tip on the cost of each meal she serves. What must be the total cost of the meals she serves in order for her to earn at least $425 each week?

help me please

Answers

Answer:

Sonya would need to serve 1500 meals

Step-by-step explanation:

425=15%(x)+200 or 425=.15(x)+200

solve for x

425=.15x+200 distribute

subtract 200 from both sides

225=.15x

divide both sides by .15 to isolate x

1500=x or x=1500

Thea does not remember in what order she added the ingredients but the last thing she added was 6- 1/4tsp. (6-quarter teaspoons). Select the only option(s) from the checklist below that could have been the last ingredient. * Cinnamon Baking Soda Pure Vanilla Extract Salt Cream of Tartar

Answers

Answer:

Cinnamon

Step-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

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).
