Translate the following sentence into an equation: "Seven added to eight times a number is three less than
twice the number."
?

Answers

[tex]let\ x\ be\ the\ unknown\ number[/tex]

[tex]8x+7=2x-3[/tex]

first choose a variable to represent the number.

when something is "..." times a number, we are multiplying that number by that value.

"seven added to eight times a number" means that we are multiplying the number by eight (8x) and then adding seven to it (+7).

"is" usually means 'equals to' so we put an equal sign there.

"three less than twice the number" means that we are multiplying the number by two (2x) and then subtracting three from it (-3).

An equation form of given statement is,  7 + 8m = 3 - 2m where m is any real valued number.

What is an equation?

"It is a mathematical statement which consists of equal symbol between two mathematical expressions."

For given question,

We have been given a statement.

We need to translate given statement into a equation.

Seven added to eight times a number is three less than twice the number.

Let 'm' be any real number.

We can rewrite above statement as,

     Seven plus to eight times 'm' is three minus twice 'm'.

⇒       7        +             8 × m           =        3      -         2 × m

So, we get an equation,

⇒ 7 + 8m = 3 - 2m

Therefore, an equation form of given statement is,  7 + 8m = 3 - 2m where m is any real valued number.

Answers

Answer:

Area of the triangle is 36√3

Step-by-step explanation:    Hope this will help

The hypotenuse of each 30 - 60 - 90 triangle is 12

The base length is  6 + 6 =  12 because the triangle is equilateral and the

altitude of the triangle divides the base into two equal parts and the altitude (DC) is the height of the triangle.    

Now you have two 30 - 60 - 90 triangles with the hypotenuse of 12, the short leg = 6 and you need to find the length of DC.

Finding DC .

a² + b² = c²

6² + b² = 12²       0r  the long leg = short leg times √3

36 + b² = 144                                       6√3

   b² = 108

    b = 6√3

Area of a triangle = 1/2bh

                             = 1/2(12)(6√3)

                             = 6(6√3) = 36√3

Answers

The Coordinate of A is (0, 1) and the equation of the graph with B coordinate is ¹/₂^(ˣ) - (¹/₂)x

How to interpret Graph Functions?

The equation of the accompanying graph is;

f(x) = aˣ

1) We want to write the coordinate of A. Thus;

f(0) = a⁰ = 1

Thus;

Coordinate of A = (0, 1)

2) The way we can tell that: 0 < a < 1 is; From figure number and inverse functions.

3) If B is the point (4, ¹/₁₆), then;

f(4) = a⁴ = ¹/₁₆

a = ⁴√(¹/₁₆)

a = ¹/₂

4) The equation of the graph with B coordinate is;

y - ax

⇒ ¹/₂^(ˣ) - (¹/₂)x

5) To get the coordinates of the point of intersection of the two graphs is;

¹/₂^(ˣ) - (¹/₂)x = ¹/₂^(ˣ)

⇒ (¹/₂)x = 0

x = 0

Thus, the coordinate of the intersection is; (0, 0)

Answers

Answer:

B. f(x) is shifted left by 6 units

Step-by-step explanation:

when we talk about translations, we know they happen along the X axis, y axis or sometimes both, in this case we see that were subtracting x by six units, so we are moving left along the x axis

ways to remember this is:

 -you count up x the RIGHT way going right

 -you count UP y

and of cource by process of ellimination we know that decreasing X goes left and decreasing y goes down

ALSO NOTE: x always goes horizontally and y always goes vertically

V = l*w*h

l = length (20 cm)

w = width (4 cm)

h = height (3 cm)

Plug all these values into the equation and solve:

V = (20 cm)(4 cm)(3 cm)

V = (80 [tex]cm^{2}[/tex])(3 cm)

V = 240 [tex]cm^{3}[/tex]

#18. estimate the perimeter and the area of the shaded figure to the nearest tenth

Answers

Answer:

Area = 22.3 m^2

Perimeter 27.4 m^2

Step-by-step explanation:

Perimeter = __ m

Area __ m^2

The area of the triangle is about 4.2,

The area of the square is 4,

The area of the semicircle is 14.1,

14.1 + 4.2 + 4 = 22.3

Area = 22.3 m^2

9.4 + 6 + 4 + 4 + 4 = 27.4

Perimeter = 27.4 m^2

Therefore the area of the shape is about 22.3 m^2 and the perimeter is about 27.4 m^2.
