On subtracting 3x² + 7x - 4 from 8x² - 6x + 2, the expression in standard form is obtained as 5x² - 13x + 6.

What is standard form?

To make mathematics easier for everyone to read, write, and work with, mathematicians from all around the world resolved to come to basic writing standards. The term "standard form" refers to this particular method.

The given expressions are -

a = 3x² + 7x - 4 and b = 8x² - 6x + 2.

Subtract a from b. The expression will be -

= (8x² - 6x + 2) - (3x² + 7x - 4)

= 8x² - 6x + 2 - 3x² - 7x + 4

= 5x² - 13x + 6

Therefore, the standard form is 5x² - 13x + 6.

Answer:

[tex] \sf \: - g - 6[/tex]

Step-by-step explanation:

The expression is,

→ -2 + 2g - (3g + 4)

Let's simplify the expression,

→ -2 + 2g - (3g + 4)

→ -2 + 2g - 3g - 4

→ (-3g + 2g) + (-2 - 4)

→ (-g) + (-6)

→ -g - 6

Hence, the answer is -g - 6.

All the correct expression are;

⇒ 2x + 6 = 2

⇒ 2(x - 4) = 6x

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Now, We have to check all the expression which has x = - 2 as a solution.

So, For first expression;

⇒ 2x + 6 = 2

Put x = -2;

LHS = 2×- 2 + 6

       = - 4 + 6

       = 2

       = RHS

Hence, This expression has a solution x = - 2

For second expression;

⇒ 2(x - 4) = 6x

Put x = -2;

LHS = 2×(- 2 - 4)

       = 2 × - 6

       = -12

RHS = 6x

       = 6×-2

       = - 12

Hence, This expression has a solution x = - 2

For third expression;

⇒ 3x + 1/2 = 1/4x + 6

Put x = -2;

LHS = 3×-2 + 1/2

       = - 6 + 1/2

       = - 11/2

RHS = 1/4x + 6

       = 1/4 × - 2 + 6

       = - 1/2 + 6

       = 11/2

Hence, This expression does not a solution x = - 2.

So, For fourth expression;

⇒ 7 - 3x = 5x + 11

Put x = -2;

LHS = 7 - 3×-2

       =  7 + 6

       = 13

RHS = 5x + 11

       = 5×-2 + 11

       = - 10 + 11

       = 1

Hence, This expression does not a solution x = - 2.

So, For fifth expression;

⇒ 3x + 15 = 2x + 9

Put x = -2;

LHS = 3×- 2 + 15

       = - 6 + 15

       = 9

RHS = 2x + 9

       = 2×-2 + 9

       = - 4 + 9

       = 5

Hence, This expression does not a solution x = - 2.

The equation of the line in slope intercept form is y = - 1 / 2 x + 4.

The equation of a line can be represented in slope intercept form as follows:

y = mx + b

where

Therefore, the equation of the line passes through the points (2, 3) and the y-intercept is 4.

Hence,

y = mx + 4

let's find slope using (2, 3)

3 = 2m + 4

3 - 4 = 2m

2m = -1

divide both sides by 2

m = - 1 / 2

Therefore, the equation of the line is y = - 1 / 2 x + 4.

(x,y) --> (x, y-2)

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

Explanation:

Choice A can be ruled out because of the jump from x to 2x, and from y to 2y. This is a dilation with a scale factor 2. Meaning the preimage enlarges to a bigger image. Specifically the larger image has side lengths twice as long as the smaller preimage. The larger image of course cannot possibly be congruent to the smaller preimage. Congruent figures must have the same corresponding side lengths.

We'll come back to choice B.

Choice C and choice D are ruled out for similar reasoning as choice A was eliminated.

-------------

To summarize the previous section: We ruled out choices A, C, and D. The only thing left is choice B.

Choice B is a translation. The jump from y to y-2 means we shift the point 2 units down. There is no left or right shifting because x stays the same.

For example, the point (5,12) moves to (5,10).

Notice that dilation is not being applied for choice B.

With any geometric translation, aka shifting, the side lengths will remain intact. Something that is 5 units long will stay 5 units long. No amount of shifting will change the distance.

Therefore, a translation preserves distances and lengths. We consider it a rigid transformation. This is why choice B will have the preimage congruent to the image.

Answer:B) (x, y) → (x, y − 2)

Step-by-step explanation:

The slope of a line perpendicular to the original line is then the negative reciprocal of 4/3, or -3/4.

Reciprocity is a reciprocal exchange of goods, services, or privileges between two parties. It is often used in business transactions and in politics to create beneficial relationships and agreements between parties.

The slope of a line perpendicular to 4x-3y=12 is calculated by finding the negative reciprocal of the slope of the original line. To find the slope of the original line, we need to rewrite the equation in the form y = mx + b, where m is the slope.
In this case, we can rewrite the equation as:
3y = 4x - 12
Yielding the slope of the original line as m = 4/3.
The slope of a line perpendicular to the original line is then the negative reciprocal of 4/3, or -3/4.

A mathematical equation is a formula that joins two statements and uses the equal symbol (=) to indicate equality. A mathematical statement that establishes the equality of two mathematical expressions is known as an equation in algebra. For instance, in the equation 3x + 5 = 14, the equal sign places the variables 3x + 5 and 14 apart. The relationship between the two sentences on either side of a letter is described by a mathematical formula. Often, there is only one variable, which also serves as the symbol. for instance, 2x – 4 = 2.

10.1 g of fluorine is required to produce 20.0 grams of FeF3

first, we have to balance the equation:

2Fe+3F₂⇒2FeF₃

The molar mass of FeF₃ is 112.84g/mol. so the num of mol(n) of FeF₃ present in 20.0g of mass is calculated as shown below:

n=20.0g/112.84g/mol

n=0.1772mol

According to the balanced equation on the macroscopic scale, 2 mol of FeF₃ is produced from 3 mol of F₂.

so, 0.1772 mol of FeF₃ is produced from X mol of F₂. where X is calculated as shown below:

X=3 mol/2mol*0.1772 mol

X=0.2658 mol

Hence, 0.2658 mol of F₂ is required. The molar mass of F₂ is 38.0g/mol

so, the mass of 0.2658 mol of F2 is calculated as:
