Solve this question 4-6n=8(n+7) do the distribute property

Mathematics

Molodets [167]3 years ago

Answer:

n=3 5/7

Step-by-step explanation:

8(n+7) Multiply each term in the parenthesis by 8

8n + 8 x 7

8n + 56

4 - 6n = 8n + 56

move variable to the left by adding its opposite to both sides

-6n - 8n + 4 = 8n - 8n +56

eliminate the opposites

-6n - 8n + 4 = 56

collect like terms by calculating the sum or difference of their coefficients

-6n - 8n

(-6 - 8)n

calculate the difference

-14n

divide both sides of the equation by -14

-14n / (-14) = 52 / (-14)

n = 52 / (-14)

n = -52/14

n= -26/7

alternative form of writing the answer is

n= -3 5/7 or n= 3.71429

I need help plz!! thx

Answer:

2nd statement describes the relation between graph of f(x) and graph of g(x).

Step-by-step explanation:  

We are told that graph of g(x)=f(x)-1 and we are asked to choose the correct statement that describes the relation between graph of f(x) and graph of g(x).

The rules for the translation are as follows:  

f(x-h)=\text{Graph shifted to right by h units}

f(x+h)=\text{ Graph shifted to left by h units}

f(x)+h=\text{ Graph shifted upward by h units}

f(x)-h=\text{ Graph shifted down by h units}    

Upon comparing our given translation with above rules we can see that our parent graph f(x) is shifted down by 1 unit to get our new graph g(x).

Therefore, graph of g(x) is the graph of f(x) translated 1 unit down and 2nd option is the right choice.

A scale drawing of a square has a side length of 9 inches. The drawing has a scale of 1 in. : 5 mi. Find the actual perimeter an
Dennis_Churaev [7]

Answer:

Area = 2025 miles²

Perimeter = 180 miles

Step-by-step explanation:

Given the following :

Scale of drawing = 1 inch : 5 miles

Length of side of the scale drawing = 9 inches

To find The actual perimeter and area of the square, we need ;

Actual length of the drawing :

1 inch = 5 miles

9 inches = (5 × 9) miles = 45 miles

Hence,

Area of a square = a²

Where a = side length

Actual side length = 45 miles

Actual area of square = 45² = 2025 miles²

Actual Perimeter of square :

Perimeter of a square = 4a

a = side length

Actual perimeter = 4(45) = 180 miles
