Which ordered pair will solve the equation 2 × 4 + x = y?A.
(5, 16)

B.
(4, 12)

C.
(3, 12)

D.
(2, 9)

Answers

Answer 1
Answer: This answer uses NMF, which you can find out about on my profile:

Preliminary work:
Following the BIDMAS order of operations, we can calculate part of it already, and that's the 2•4, which equals 8.
Therefore, the equation now reads:
8+x = y

x = 5:
8+5 = 13
13 ≠ 16
13 ≠ y

x = 4:
8+4 = 12
12 = 12
12 = y

Therefore, the pair is (4, 12)

The endpoints of AB are A(9,4) and B(5,-4). The endpoints of its image after a dilation ar A(6,3) and B(3,-3). a. explain how to find te scale factor. b. locate the center of dilation. show your work

Answers

Look at the picture for the answer.

Final answer:

The scale factor of the dilation is calculated by dividing the length of the line after dilation by the length of the initial line. The length of a line is calculated using the distance formula. The center of dilation is the point from which the shape scales, but we can't determine its location without more information.

Explanation:

To find the scale factor of a dilation in a two-dimensional plane, we divide the length of the line after dilation by the length of the initial line. The length of a line can be calculated using the distance formula which is √[(x₂ - x₁)² + (y₂ - y₁)²].

For AB, the distance will be √[(5 - 9)² + (-4 - 4)²] = √[(-4)² + (-8)²] which equals √80. For A'B', the distance will be √(3 - 6)² + (-3 - 3)² = √[(-3)² + (-6)²] which equals √45. The scale factor (k) of the dilation is the ratio of these distances, so k = √45 / √80 which simplifies to √(9/16) or 3/4.

Unfortunately, without more information, such as a fixed point in the original shape, we can't determine the exact location of the center of dilation. But, conceptually, it's the point that the shape is scaling towards or away from during the dilation.

(add 4 to both sides)

6n=30

Divide both sides by 6

n=5

HELPPP ASAPPP! PLZWhich system has no solution?
A.4y = 2x – 6

B.3x + 5y = 7
4x = 2y – 5

C.2y = 4x + 2

D.2x = 5y + 4
15y = 6x – 12

Answers

Answer : D

2x=5y+4

15y=6x-12

Solve 2x=5y+4 for x

Divide both sides by 2

2x/2=(5y+4)/2

x = 5/2 y +2

Substitute 5/2 y +2 for x in 15y=6x-12

15y= 6x-12

15y= 6(5/2 y +2 ) -12

Simplify both sides of the equation

15y=15y

Add -15y to both sides

15y-15y= 15y-15y

0=0
