Answer:

84 cm^2

Step-by-step explanation:

Area of triangle + area of rectangle

Area of triangle = 1/2*l*b

= 1/2*8*3= 12 cm^2

Area of rectangle = l*b

= 12*6 = 72 cm^2

Total area= 72+12

= 84 cm^2

Answer:

$1,320

Step-by-step explanation:

To find the area of the bedroom, you must multiply the length and the width. 15 multiplied by 12 is 180, so the area of the bedroom is 180 square feet. There are three feet in a yard, so you must divide the area of the bedroom in feet by 3 in order to get the area of the bedroom in yards. 180 divided by 3 is 60, so the area of the bedroom is 60 square yards. In order to find how much it will cost to carpet the room, you must multiply the area of the bedroom in yards by how much carpeting costs per square yard. 60 multiplied by 22 is 1,320, so it will cost $1,320 in order to carpet the room.

Answer:

Step-by-step explanation:

The x-coordinate of a point is the number units to the right of the y-axis where the point may be found. Translating the point to the right adds to the x-coordinate. Translating to the left subtracts from the x-coordinate.

The y-coordinate of a point is the number of units above the x-axis where the point may be found. Translating the point upward adds to the y-coordinate. Translating downward subtracts from the y-coordinate.

__

When a point is translated 3 units right and 2 units down, its x-coordinate has 3 added to it, and its y-coordinate has 2 subtracted from it. We can summarize the transformation like this:

  (x, y) ⇒ (x +3, y -2)

Applying this transformation to the given points, we find ...

  H(0, 0) ⇒ H'(3, -2)

  I(-3, -1) ⇒ I'(0, -3)

  J(-1, -2) ⇒ J'(2, -4)

Answer: Suppose y varies directly with x. Write a direct variation equation that relates x and y.

Step-by-step explanation:

Answer is y = -5x

The equation for y varies directly with x is, y = - 5x.

A ratio is a comparison between two similar quantities in simplest form.

Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.

In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.

Given, y varies directly with x.

Therefore,

y ∝ x.

y = kx, where k is the proportionality constant.

At y = - 10 when x = 2.

- 10 = 2k.

k = - 5.

So, y = - 5x.

========================================================

Explanation:

For any parallelogram, the diagonals cut each other in half. Formally this is known as bisection.

What this means is that the pieces AE and CE are the same length.

AE = CE

6x-8 = 2x+24

6x-2x = 24+8

4x = 32

x = 32/4

x = 8

Then we can calculate the length of each piece mention

Both pieces are 40 units long to confirm we have the correct x value.

Therefore,

AC = AE + CE = 40+40 = 80

Answer:

See below.

Step-by-step explanation:

Question 1

a = -2 and x = -6

| a + x | / 2 - | a - x | / 2

| -2 + -6 | / 2 - | -2 + 6 | / 2

| -8 | / 2 - | 4 | / 2

8/2 - 4/2

= 4/2

= 2

Question 2

a = -5, b = 4, c = 1, d = -3

| a - b | - | c + d |

| -5 - 4 | - | 1 - 3 |

| -9 | - | -2 |

= 9 - 2

= 7

Step-by-step explanation:

A function from a set X to a set Y assigns to each element of X exactly one element of Y. The value of g(3) is 3

A function from a set X to a set Y assigns to each element of X exactly one element of Y.

We need to find the value of g(3).

From the question, we have

g(x)= x-1,  -2≤x<-1

g(x)= 2x+3, -1≤x<3

g(x)= 6-x,     x≥3

The value 3 is in the function g(x)=6-x

When x is 3

g(3)=6-3

Subtract 3 from 6.

g(3)=3

Therefore value of function g(3) is 3.
