What is Transformation?

A point, line, or geometric figure can be transformed in one of four ways, each of which affects the shape and/or location of the object. Pre-Image refers to the object's initial shape, and Image, after transformation, refers to the object's ultimate shape and location.

Given:

y = 2x - 4.

and, if the equation is changes to y= 2x- 2.

as, function goes from y = 2x - 4 + 2

y= y = 2x - 2

The addition of 2 shows there is shifting upside.

Thus, The line will shift up 2 units.

2000 tickets were sold in an exhibition on Saturday. The cost of a ticket for an adult is $4 and for a child is $2. The total amount collected on Saturday was $6400. Find the number of adult tickets and child tickets sold on Saturday

Answers

Answer:

Let x = # of adult tickets sold (at $4.00 each)

Let y = # of child tickets sold (at $2.00 each)

We can take the above information, along with the 2000 tickets sold and the $6,400 collected, to get the following two math statements:

x + y = 2000    (Total unknown number of $4.00 + total unknown number of $2.00 tickets, equals a total of 2,000 tickets sold

4x + 2y = 6400  ($4.00 * unknown number of $4.00 tickets + $2.00 * unknown number of $2.00 tickets, equals the total of $6,400 collected in ticket sales

So, write these as:

x + y = 2000

4x + 2y = 6400

Take the first equation:  Turn it into a y= statement, by subtracting 'x' from both sides, to get:

y = 2000 - x

Next, go to the 2nd equation.  Where you see the 'y', substitute the y-value in its place:  '2000 - x'

This gives you:

4x + 2 (2000 - x) = 6400

This then gives us:  4x + 4000 -2x = 6400

Collect like terms to get:

2x + 4000 = 6400

Subtract 4000 from both sides to get:

2x = 2400

Next, divide both sides by 2, to get x = 1200

We now know that there were 1,200 adult ($4.00) tickets sold; put this information back into the original equation:

1200 + y = 2000

Next, subtract 1200 from both sides, so that we can solve for y; which is:

y = 800

Next, check our work, by substituting back into the two original equations:

1200 + 800 = 2000    [Check]

4 * 1200 + 2 * 800 = 4800 + 1600 + 6400    [Check]

So:  1,200 tickets sold at $4.00 each; and 800 tickets sold at $2.00 each, final and correct answer.
Hi. So, you know that there were 2000 tickets sold on Saturday. You also know that the total amount collected was $6400. To find out how many adult tickets and child tickets were sold, simply follow these steps:

1.)  First find out how many ADULT tickets were sold. Divide total tickets with price of one ticket.       2000/4= 500 adult tickets were sold.

2.) Now find out CHILD ticket. Same thing as first.     2000/2= 1000 child tickets were sold.

>>>>So, on Saturday, 500 adult tickets were sold, and 1000 child tickets were sold. Hope that helps! :)

Emichee can you help me? A cylinder has a base with a radius of 8 inches and a height of 15 inches. What is the volume of the cylinder? ( Use \pi=3.14)A. 376.8 in^3
B. 753.6 in^3
C. 3014.4 in^3
D. 12,057.6 in^3

Answers

The volume of a Cylinder is:

V=A_b*h

the base is a circle, so

A_b=\pi*r^2

replacing

V=\pi*r^2*h

now we have the values

V=3.14*8^2*15

\boxed{\boxed{V=3014.4~in^3}}
