There are two approaches to solving the equation -3x + 10 = 4x - 20

Subtract 4x from both sides. OR Add 3x to both sides.

–7x + 10 = –20 OR 10 = 7x – 20

C. 6(6n – 2)
D. 4(3n – 2)
E. 4n + 22 – 12 + 8n

Answers

Answer:

B and D

Step-by-step explanation:

B= 4(3n-2)

D=12n-8 which equals 4(3n-2)

Option B 11n + 4 + n –12 and D 4(3n – 2) are the expressions that are equivalent to 12n-8.

What are equivalent expressions?

Those expressions that might look different but their simplified forms are the same expressions are called equivalent expressions. To derive equivalent expressions of some expressions, we can either make it look more complex or simple. Usually, we simplify it.

We are given an expression as; 12n – 8.

A. 3n + 4 + 3n + 4 + 4n

= 3n+3n+4n+4+4

=10n+8

B. 11n + 4 + n –12

=11n+n+4-12

=12n-8

C. 6(6n – 2)

=36n-12

D. 4(3n – 2)

=12n-8

E. 4n + 22 – 12 + 8n

=4n+8n+22-12

=12n+10

Therefore, Option B 11n + 4 + n –12 and D 4(3n – 2) are the expressions that are equivalent to 12n-8.

A. y= x +8
B. y= x - 8
C. y = 8x +8
D. y = 8x - 8

Answers

Answer:

d

Step-by-step explanation:

The equation of the line in slope -intercept form is y=x-8, Option b is correct.

What is Slope of Line?

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

From the graph let us take two points of line joining which are (8, 0) and (0, -8).

m=-8-0/0-8=1

So slope of line is 1.

Now let us find find the y intercept

0=1(8)+b

0-8=b

b=-8

Slope intercept form of line is y=x-8

Hence,  the equation of the line in slope -intercept form is y=x-8, Option b is correct.

I’m pretty sure it’s $125-$52= 73. 73/3

. Simplify an expression for the perimeter of the equilateral triangle shown below.

Answers

Answer:

1.75×2-2

Step-by-step explanation:

look at the answer

The perimeter of the equilateral triangle with side length 1.75x - 2 is 5.25x - 6.

What is Perimeter?

Perimeter of a geometrical shape is defined as the total boundary length. The perimeter of a shape can be calculated by adding the length of all the sides.

Perimeter of regular shape can be calculated by multiplying the length of the side with the total number of sides since a regular shape has all sides equal.

Here, we have an equilateral triangle with length of a side = 1.75x - 2.

Equilateral triangle is a regular shape, with all it's sides are equal.

Perimeter of an equilateral triangle with side length x is 3x.

Therefore,

Perimeter of this triangle = 3 ( 1.75x - 2 )

By distributive property, a (b + c) = ab + ac.

Perimeter = (3 × 1.75x) - (3 × 2)

                = 5.25x - 6

Hence the perimeter of the equilateral triangle shown is  1.75x - 2.

What is the slope of the line that passes through the points (4, 6)(4,6) and (-16, -18) ? (−16,−18)? Write your answer in the simplest form.

Answers

The slope of the line that passes through the points (4, 6)(4,6) and (-16, -18) is to be considered as the 1.2.

Calculation of the slope of the line:

here we used the following formula

So,

[tex]= y_2-y_1\div x_2-x_1[/tex]

So,

-18-6=-24

And,

-16-4=-20

Now

[tex]= -24\div -20[/tex]

= 1.2

Hence, The slope of the line that passes through the points (4, 6)(4,6) and (-16, -18) is to be considered as the 1.2.

The slope of the line that passes through the points (4, 6) and (-16, -18) is; 6/5.

What is the slope?

The slope is the ratio of the vertical changes to the horizontal changes between two points of the line. Slope of parallel lines are same. Slopes of perpendicular lines are negative reciprocal of each other.

[tex]m = \dfrac{y-q}{x-p}[/tex]

Given that the line that passes through the points (4, 6) and (-16, -18)

WE need to find the slope of the line.

Since, [tex]m = \dfrac{y-q}{x-p}[/tex]

Therefore, m = -18 - 6 / -16 - 4

m = 24 / -20

m = 6/5

Hence, The slope of the line that passes through the points (4, 6) and (-16, -18) is; 6/5.
