Solution,
Let x is the results
From question we know
For x if divides by -3 we can get 12 so
So x/-3=12
Or. x= 12 x -3
So x= -36 is answer
Conclusion : = -36 number divided by -3 gives 12 as the results.

On a coordinate plane, quadrilateral Q R S T has points (0, 2), (negative 4, 0), (0, negative 3), and (4, 0).

Afina-wow [57]

By applying the definitions of rigid transformation ((x, y) → (0.5 · x, 0.5 · y)) and dilation, we conclude that the coordinates of Q'(x, y) are (0.1).

<h3>How to apply rigid transformations on a point</h3>

Herein we must apply a rigid transformation into a given point to determine an image. Rigid transformations are transformations applied on a geometric locus such that Euclidean distance is conserved. Dilations are a kind of rigid transformations such that:

(x, y) → (k · x, k · y), for k > 0

If we know that Q(x, y) = (0, 2) and k = 0.5, then the coordinates of Q' are:

Q'(x, y) = (0.5 · 0, 0.5 · 2)

Q'(x, y) = (0, 1)

By applying the definitions of rigid transformation ((x, y) → (0.5 · x, 0.5 · y)) and dilation, we conclude that the coordinates of Q'(x, y) are (0.1).

What is the inverse matrix that can be used to solve this systems of equations

Gala2k [10]

Step-by-step explanation:

The answer is OPTION C

Find the Inverse of a 3x3 Matrix.

First

Find the Determinant of A(The coefficients of e

Proceed towards finding the CO FACTOR of the 3x3 Matrix.

+. - +

A= [ 1 -1 -1 ]

[ -1 2 3 ]

[ 1 1 4 ]

The determinant of this is 1.

Find the co factor

| 2 3 | |-1 3 | |-1 2 |

| 1. 4. | |1 4 | |1. 1 |

|-1. -1 | |1 -1 | |1 -1

| 1. 4 | |1. 4| |1 1|

|-1. -1 | |1 -1 | |1. -1

|2. 3| |-1. 3| |-1 2|

After Evaluating The Determinant of each 2x 2 Matrix

You'll have

[ 5 7 -3]

[3 5 -2 ]

[-1 -2 1]

Reflect this along the diagonal( Keep 5,5 -2)

Then switching positions of other value

No need of Multiplying by the determinant because its value is 1 from calculation.

After this

Our Inverse Matrix Would be

[ 5 3 -1 ]

[7 5 -2 ]

[ -3 -2 1]

THIS IS OUR INVERSE.

Find the value of x m<2= 10x + 10

jarptica [38.1K]

Answer: x = 12

Step-by-step explanation:

a) Linear Pair: 110° + ∠a = 180° --> ∠a = 70°

b) congruent sides implies congruent angles --> ∠b = 70°

c) Triangle Sum Theorem: ∠a + ∠b + ∠c = 180

70° + 70° + ∠c = 180°

∠c = 40°

d) Complimentary Angles: ∠c + ∠d = 90°

40° + ∠d = 90°

∠d = 50°

∠2) Linear Pair: ∠d + ∠2 = 180°

50° + ∠2 = 180°

∠2 = 130°

x) m∠2 = 130°

10x + 10 = 130°

10x = 120

x = 12

Help me please with this

Nutka1998 [239]

Answer:

Step-by-step explanation:

Solving the inequality

$\frac{x+3}{6}$ > $\frac{x}{4}$ + 1

Multiply through by 12 ( the LCM of 6 and 4 ) to clear the fractions

2(x + 3) > 3x + 12

2x + 6 > 3x + 12 ( subtract 2x from both sides )

6 > x + 12 ( subtract 12 from both sides )

- 6 > x , that is

x < - 6

The only value less than - 6 is - 10

Thus x = - 10 is a solution to the inequality
