Step-by-step explanation:

The linear function below represents the total cost in dollars, y, to camp at state Park for x nights. What is most likely represented by the y intercept of the function

y=14x +22
a-The number of nights spent camping
B-The cost per night to camp at the park
C-The number of people camping
d- The cost of a one time fee for a camping pernit​

Answers

Answer:

D

Step-by-step explanation:

Since you already know the cost per night and the total cost, you would need to multiply the number of people camping there, therefore, '22' can't be the number of people camping. That makes the final answer D.

What are the resulting coordinates of triangle A′B′C′ after reflecting triangle ABC across the origin if the vertices of triangle ABC are A(2, 6), B(–4,–7), and C(5, –4)?
Question 8 options:

A)

A′(2, –6), B′(–4,7), C′(5, 4)

B)

A′(6, 2), B′(–7,–4), C′(–4, –5)

C)

A′(–2, –6), B′(4,7), C′(–5, 4)

D)

A′(–2, 6), B′(4,–7), C′(–5, –4)

Answers

Answer:

C

Step-by-step explanation:

When reflecting across the origin, negetives become positives and positives become negetives.

Hope that helps!

The coordinates of the new triangle after reflecting triangle ABC across the origin will be - A' (-2, -6), B'(4, 7) and C'(-5, -4).

We have a triangle ABC with coordinates A (2, 6), B(-4, -7) and C(5, -4)

We have to find the coordinates of the resulting triangle if the triangle ABC is reflected across the origin.

A point P(x, y) is reflected across the origin O(0, 0). What will be its new coordinates?

A point P (x, y) when reflected across the origin, its new coordinates become - P'( -x, -y).

In the question given to us, we have a triangle with coordinates A (2, 6), B(-4, -7) and C(5, 4).

When this triangle is reflected across the origin, then the new coordinates will be -

A (2, 6) → A' (-2, -6)

B (-4, -7) → B' (4, 7)

C (5, -4) → C' (-5, 4)

Hence, the coordinates of the new triangle after reflecting triangle ABC across the origin will be - A' (-2, -6), B'(4, 7) and C'(-5, -4).

Fifty identical balls are numbered 1 through 50 and placed in a bucket. Then, a ball is randomly selected from the bucket. Select a decimal for each blank to make the sentence true.

Answers

Answer:

Blank 1: 0.12

Blank 2: 0.18

Step-by-step explanation:

Out of 50, there are 6 numbers that contain the digit 5, (5, 15, 25, 35, 45, 50)

so when you take 0.06 and multiply it by 2 (because you have to multiply 50 by 2 to get 100), you get 0.12.

For blank 2, there are 9 single digit numbers, (1, 2, 3, 4, 5, 6, 7, 8, and 9) equaling 0.09. Multiply that by 2 and you get 0.18.
