Simplify the following expression : (2x + 7y) (x – 3y)

-3(y+3)=2y+3 <br> Please solve this question

NARA [144]

Answer:

y=-2.4y

Step-by-step explanation:

First you want to restate the problem.

-3(y+3)=2y+3

Now distribute the negative.

-3y-9=2y+3

Add 3y to both sides.

-9=5y+3

Subtract 3 from both sides.

-12=5y

And solve.

-2.4=y

To isolate a single variable when rearranging equations, move all other variables to the ___________of the equation by using ___

noname [10]

Answer:

Other side, the opposite function, on both sides of the equation, in the numerator, not the denominator

Step-by-step explanation:

To isolate a single variable when rearranging equations, move all other variables to the other side of the equation by using the opposite function on them and remembering to perform that operation on both sides of the equation. Make sure the rearrangement has the target variable in the numerator, not the denominator.

Solve for the following equation <br> 1/2(2 – 4x) + 2x = 13

mart [117]

Answer:

no solution

Step-by-step explanation:

1/2(2-4x)+2x=13

We simplify the equation to the form, which is simple to understand

1/2(2-4x)+2x=13

Simplifying:

+ 0.5*(2-4x)+2x=13

Reorder the terms in parentheses

+(+1-2x)+2x=13

Remove unnecessary parentheses

+1-2x+2x=+13

We move all terms containing x to the left and all other terms to the right.

-2x+2x=+13-1

We simplify left and right side of the equation.

0x=+12

0=12

The left and right sides are not equal, therefore there is no solution. This equation is invalid.

HELP PLEASE! Square T was translated by the rule (x + 2, y + 2) and then dilated from the origin by a scale factor of 3 to creat

Sveta_85 [38]

The statement that explains why the squares are similar is

Option C. Translations and dilations preserve betweenness of points; therefore, the corresponding sides of squares T and T″ are proportional.

<h3>Further explanation</h3>

<em>There are several types of transformations:</em>

<em>Translation</em>
<em>Reflection</em>
<em>Rotation</em>
<em>Dilation</em>

Let us now tackle the problem!

$\texttt{ }$

This problem is about Translation and Dilation.

<em>Properties of </em><em>Translation</em><em> of the images compared to pre-images:</em>

preserve Side Length
preserve Orientation
preserve Collinearity
preserve Betweenness of Points

$\texttt{ }$

<em>Properties of </em><em>Dilation</em><em> of the images compared to pre-images:</em>

not preserve Side Length
not preserve Orientation
preserve Collinearity
preserve Betweenness of Points

$\texttt{ }$

From the information above, we can conclude that:

Option A is not true because Dilations do not preserve side length.

Option B is not true because Dilations do not preserve orientation.

Option C is true because Translations and Dilations preserve betweenness of points.

Option D is not true. Although Translation and Dilations preserve collinearity but it cannot be related to the corresponding angles are congruent.
