Solve system by elimination

9x + 3y = 24
10x - 2y = 0

Answers

Answer 1

Answer:

(1, 5 )

Step-by-step explanation:

Given the 2 equations

9x + 3y = 24 → (1)

10x - 2y = 0 → (2)

Multiplying (1) by 2 and (2) by 3 and adding the result will eliminate the y- term

18x + 6y = 48 → (3)

30x - 6y = 0 → (4)

Add (3) and (4) term by term to eliminate y

48x + 0 = 48

48x = 48 ( divide both sides by 48 )

x = 1

Substitute x = 1 into either of the 2 equations and solve for y

Substituting into (1)

9(1) + 3y = 24

9 + 3y = 24 ( subtract 9 from both sides )

3y = 15 ( divide both sides by 3 )

y = 5

solution is (1, 5 )

In the xy-plane, a line segment is dilated by a scale factor of 2. The dilation is centered at a
point not on the line segment. Select from the drop-down menus to make a true statement about the line segment and its image. The like segments are choose, and the length of the image is choose the length of the original line segment

Answers

The line segments are parallel and the length of the image is perpendicular to the length of the original line segment.

Why is the line segment by a scale factor. ?

The line segment is a part of the line and is bounded by the two distinct endpoints. The line segment that represents the x, y plane is dilated by a factor of 2 and this dilation is centered around the point and not a line. Hence are line segment is parallel and perpendicular to the length of the original point shown in the image.

A module house is made by sticking a triangular prism on top of a rectangular block, as shown in the diagram.

Answers

Answer:

d

Step-by-step explanation:

The volume of the triangular prism.

= Base area x length of the prism

The volume of the rectangular block.

= Length x width x height

The volume of the model house is 1260 cubic feet.

Option A is the correct answer.

What is a rectangle?

A rectangle is a two-dimensional shape where the length and width are different.

The area of a rectangle is given as:

Area = Length x width

We have,

Module house:

Triangular prism on top and a rectangular block.

The volume of the triangular prism.

= Base area x length of the prism

= (1/2 x 12 x 4) x 15

= 24 x 15

= 360 cubic feet

The volume of the rectangular block.

= Length x width x height

= 12 x 15 x 5

= 900 cubic feet

The volume of the block house.

= Volume of the triangular prism + Volume of the rectangular block

= 360 + 900

= 1260 cubic feet

Thus,

The volume of the model house is 1260 cubic feet.

Option A is the correct answer.

Answers

Answer:

(2,-2)

Step-by-step explanation:

The first step is to substitute y in the first equation with the right side of the second equation because they both equal to y.

-3x+4 = 4x-10

-3x-4x+4-4 = 4x-4x-10-4

-7x = -14

-7x/-7 = -14/-7

x = 2

Plugin 2 for x for either equation to solve for y, I'll be using the second equation, but either one is fine.

y = 4(2)-10

y = 8-10

y = -2

Plugin x = 2 and y = -2 into (x,y), and you get (2,-2)
