Answer:

1000 x .15 = 150 The car will lose 15% value after the first year which is $150. Subtract 150 from 1000 and the new value would be $850.

5020 x .15 = 753 This car lost 15% after the first year which is $753. Subtract 753 from 5020 and the new value would be $4287.

Answer:

f(- 2) = - 9.2

Step-by-step explanation:

To evaluate f(- 2) substitute x = - 2 into f(x) , that is

f(- 2) = 3.6(- 2) - 2 = - 7.2 - 2 = - 9.2

(1, - 12 )

Step-by-step explanation:

Moving left 3 units means subtracting 3 from the x- coordinate

Moving down 6 units means subtracting 6 from the y- coordinate

(4, - 6 ) → (4 - 3, - 6 - 6 ) → (1, - 12 )

x + 81 + 124 + 104 = 360 add like terms

x + 309 = 360 subtract 309 from both sides

x = 51

The number is -12 in the inequality x + 4y ≥ ?

In mathematics, an inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions.

Given is a system of linear inequalities represented by the graph [attached]

We need to find the missing number,

y ≥ 2x – 2 and x + 4y ≥ ?

The linear equation with slope m and intercept c is given as follows.

y = mx + c.

The formula for slope of line with points (x₁, y₁) and (x₂, y₂) can be expressed as,

m = y₂ - y₁ / x₂ - x₁

The orange line intersects y-axis at (0, -2), therefore the y-intercept is -2.

The orange line intersects the points that are (1, 0) and (0, -2).

The slope of the line can be obtained as follows,

m = 2,

The slope of the line is m = 2.

Therefore, the orange line is y ≥ 2x – 2.

The blue line intersects y-axis at (0, -3), therefore the y-intercept is -3.

The blue line intersect the points that are (-4, -2) and (0, -3).

The slope of the line can be obtained as follows.

m = -1/4

The inequalities is x + 4y ≥ b passes through the point (0, -3).

0 + 4(-2) ≥ b

-12 ≥ b

Hence the number is -12 in the inequality x + 4y ≥ ?

First we subtract 18x from both sides

3x²-18x=0

Factor out a 3x

3x(x-6)=0

This means that x is either 0 or 6

Answer:

35 meters

Step-by-step explanation:

Since 1cm=10meters, we can do 3.5cm=how many meters?

To get from 1 to 10 we multiply by 10.

So we can do 3.5x10 to get 35 meters.

Step-by-step explanation:

Answer:

a. (5x - 2)° + (2x - 2)° + x° = 180°

b. m<113°,

m<K = 44°,

m<L = 23°

Step-by-step explanation:

Given:

m<J = (5x - 2)°

m<K = (2x - 2)°

m<L = x°

Required:

a. the equation to find x,

b. m<J, m<K, and m<L

Solution:

a. m<J + m<K + m<L = 180° (sum of triangle)

Substitute

(5x - 2)° + (2x - 2)° + x° = 180°

Solve for x

5x - 2 + 2x - 2 + x = 180

Add like terms

8x - 4 = 180

8x - 4 + 4 = 180 + 4

8x = 184

8x/8 = 184/8

x = 23°

b. ✔️m<J = (5x - 2)°

Plug in the value of x

m<J = 5(23) - 2 = 113°

✔️m<K = (2x - 2)° = 2(23) - 2

m<K = 44°

✔️m<L = x = 23°

Answer:

Prism Y

[tex]Height = 12in[/tex]

[tex]Length = 6in[/tex]

[tex]Width = 4in[/tex]

[tex]Volume = 288in^3[/tex]

Prism Z

[tex]Height = 18in[/tex]

[tex]Length =10in[/tex]

[tex]Width = 10in[/tex]

[tex]Volume = 1800in^3[/tex]

[tex]Total = 2088in^3[/tex]

Step-by-step explanation:

Given

See attachment for sculpture

Solving (a) The dimension and volume of Y

From the attachment

[tex]Height = 18 - 6[/tex]

18 in is the height of Z and 6in represents the length (height) of the unoccupied space by Y

So:

[tex]Height = 12in[/tex]

[tex]Length = 16 - 10[/tex]

16 in is the total length of the sculpture and 10 in represents the length of Z

So:

[tex]Length = 6in[/tex]

[tex]Width = 10 - 6[/tex]

10 in is the width of Z and 6in represents the length (width) of the unoccupied space by Y

So:

[tex]Width = 4in[/tex]

Hence, the dimension of Y is:

[tex]Height = 12in[/tex]

[tex]Length = 6in[/tex]

[tex]Width = 4in[/tex]

Volume is then calculated as:

[tex]Volume = Length * Width * Height[/tex]

[tex]Volume = 12in * 6in * 4in[/tex]

[tex]Volume = 288in^3[/tex]

Solving (b) The dimension and volume of Z

As identified in (a), the dimensions of Z are:

[tex]Height = 18in[/tex]

[tex]Length =10in[/tex]

[tex]Width = 10in[/tex]

Volume is then calculated as:

[tex]Volume = Length * Width * Height[/tex]

[tex]Volume = 18in * 10in * 10in[/tex]

[tex]Volume = 1800in^3[/tex]

Solving (c): Total volume of the sculpture.

To do this, we simply add up the volumes of Y and Z.

So, we have:

[tex]Total = 288in^3 + 1800in^3[/tex]

[tex]Total = 2088in^3[/tex]

Answer:

(C) j/j+80 and 36/k+36

Step-by-step explanation:

From the table attached :

Total Email (positive + negative) = j + 80

Number of positive Emails = j

Fraction of positive emails = (number of positive  / total number of emails) = j / (j + 80)

Total phone calls  (positive + negative) = 36 + k

Number of positive Emails = 36

Fraction of positive emails = (number of positive  / total number of emails) = 36 / (k + 36)
