Answer with explanation:

Coordinates of vertices of A, B and C are =(1,1),(2,3), and ,(2,1).

→When Triangle ABC , is reflected across X- axis

Coordinates of Vertex A, B and C after reflection=(1,-1), (2,-3) and (2,-1).

→Now, the triangle ABC, is rotated by 90 degrees in clockwise Direction

When a point , (h,k) is rotated by 90 degree, the coordinates of image will be , (k, -h).

So,  Coordinates of Vertex A, B and C after  rotated by 90 degrees in clockwise Direction=A"(-1,-1), B"(-3,-2), C"(-1,-2).

→When , A"(-1,-1), B"(-2,-3), C"(-1,-2) is reflected across the line, y=c :

These Points lies in third Quadrant.So, after reflection through line, y=c,triangle will go in the second Quadrant.So, the coordinates of vertices of ΔABC  will be

A'(-1,1)

B'(-2,3)

C'(-1,2)

Hillel is juggling flaming torches to raise money for charity. His initial appearence raises $500, and he raises $15 for each mi
7nadin3 [17]

Answer:

r(t) = 15t+500

Step-by-step explanation:

Since the amount of money (r) is a function of the time (t) we will make it the y-value.  t is how much time and he gets $15 a minute so we multiply t by 15.  500 is how much he gets paid for doing it.  If he showed up and just left, he would still get 500.

You pack sandwiches for a hike with your friends. Each sandwich takes 2 slices of bread, and each hiker eats one sandwich.
Citrus2011 [14]

<u>Given</u><u> </u><u>that</u><u>:</u><u>-</u>

→ 1 sandwich = 2 slices of bread.

→ 1 hiker = 1 sandwich.

→ Then we have to find number of bread slices for n hikers .

→ Number of bread slices for 1 hiker = 2

→ Number of bread slices for 2 hikers = 2 × 2

→ For 3 hikers = 3 × 2

So in similar way

→ Number of bread slices for n hikers = 2×n → 2n

So <u>2</u><u>n</u><u> </u> is the answer.
