Answer:

Step-by-step explanation:

(x, y) -----> (x + 4, y - 1)

Adding 4 to the x means you move right 4. Subtracting 1 from the y means you move down one.

The next transformation (-(x + 4), y - 1)

If you look at the x coordinate and the transformation that is being applied

(-(x+4) that negative means you are taking the opposite of the x coordinate.

When you take the opposite of the x coordinate, it means you reflect it over the y axis.

Answer:

A theater has 60 seats in the first row, 68 seats in the second row, 76 seats in the third row,

and so on in the same increasing pattern. If the theater has 20 rows of seats, how many seats are in the theater?

220 seats in the theater.

So if the increasing pattern is +8, and we need to determined how many seats there will be if there where 20 rows, then you would need to multiply.

1. 8 x 20 = 160

2. 160 + 60 = 220

Question 2

Oliga [24]

Answer:

Step-by-step explanation:

you want the trinomial (x*x - 6x + __ ) to be written as a binomial squared.

So we would need to realize that the constant would be equal to (-6/2)^2 =(-3)^2 = 9

We have completed the square.

f(x) = 4*( x - 3)^2 + 20 is now in Vertex Form

Dilating a triangle changes the size of the triangle but does not change its shape. true or false?

____ [38]

<h3>Answer;</h3>

The correct answer is true

<h3>Explanation;</h3>

Dilation is a type of transformation which stretches and reduces the size of the original figure.

A dilation has a center of dilation and a dilation scale factor. If the scale factor is less than one then the original size will shrink, and if the scale factor is greater than one then the figure will increase in size.

Dilation transformation does not alter the shape of a figure but alters the size by making it bigger or smaller.

Answer:

Not a Solution

Step-by-step explanation:

We are given two inequalities which are

y ≤ x -4 .............(i)

-x+3y>-4 ............(ii)

Also we are given an ordered pair which is (5, 1/3)

Now from this order pair we see that

x = 5 and y = 1/3

Because in an ordered pair the first element represents the x value while the second value represent the y value

Now to find whether this order pair satisfies the given inequality or not we have to plugin the values of x and y in both inequalities separately and see whether it satisfies the in equality or not

Taking First inequality:

which is

y ≤ x -4

Putting x = 5 and y = 1/3 in inequality

it becomes

$\frac{1}{3}$ ≤ 5 -4

$\frac{1}{3}$ ≤ 1 ∵ which is true

So this inequality holds the order pair

Taking second inequality:

which is

-x+3y> -4

Putting x = 5 and y = 1/3 in inequality

it becomes

-5+ $\frac{1*3}{3}$ > -4

-5+1 >-4

-4>-4 ∵ which is false because - 4 = - 4

So this inequality does not holds the order pair

So the order pair is not solution of the given inequalities because of the reason that second inequality is not satisfied
