Answer:

a function of x, the number of miles driven in a year.

Step-by-step explanation:

The slope of the line represents the cost of the maintenance and the cost of the fuel. Then the correct option is D.

A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.

In addition to fuel and maintenance, Rachel pays $1,000 a year for insurance. The equation will be

C = (0.05 + 0.14)x + 1000

C = 0.19x + 1000

Then the slope of the line will be

Slope = 0.19

The slope of the line represents the cost of the maintenance and the cost of the fuel.

Answer:

The number is 5

BRAINLIEST, PLEASE!

Step-by-step explanation:

8x + 2 = 2(21)

8x + 2 = 42

8x = 40

x = 5

In the expression, the value of number is 5.

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

We can to given that;

The algebraic expression is,

''A number is multiplied by 8, and that product is added to 2. The sum is equal to the product of 2 and 21.''

Now,

Let a number = x

Hence, We can formulate;

⇒ x × 8 + 2 = 2 × 21

⇒ 8x + 2 = 42

Subtract 2 both side,

⇒ 8x + 2 - 2 = 42 - 2

⇒ 8x = 40

Divide by 8;

⇒ x = 5

Thus, The value of number = 5

Answer:

t = d/r; t = 5

Step-by-step explanation:

Hi there!

1) Isolate t

d = rt

Divide both sides by r

d/r = rt/r

d/r = t

t = d/r

2) Solve for t when distance is 40 and the rate is 8

t = d/r

Replace d with 40 and rate with 8

t = 40/8

t = 5

The shape is 2 triangles. Find the area of each one and add them together.

1/2 x 6 x 10 = 30

1/2 x 10 x 12 = 60

30 + 60 = 90

Area = 90 square inches

Area of Trapezoid = ½ (a + b) h

= ½ (12 + 6) 10

= ½ × 18 × 10

= 1 × 9 × 10

= 9 × 10

= 90 in.²

The perimeter of the rectangle will be 6√6 units.

Let W be the rectangle's width and L its length. The perimeter of the rectangle will be defined as the total length of all of its sides. So the rectangle's perimeter will be given as,

Perimeter of the rectangle = 2(L + W) units

A rectangle has a length of 2√6 and a width of √6. Then the perimeter of the rectangle is given as,

P = 2 (2√6 + √6)

Simplify the equation, then we have

P = 2 (2√6 + √6)

P = 2 (3√6)

P = 6√6 units

The perimeter of the rectangle will be 6√6 units.

Line segment X Z

Answer:

Line segment X Z

Step-by-step explanation:

Hi! I'm happy to help!

To solve for the area of a semi-circle, we just need to find the area of a circle, and divide it by 2.

The equation for area of a circle is A=[tex]\pi[/tex]r²

It says we can use 3.14 for pi, so we can write our equation like this:

A=3.14(r²)

Since we are dealing with half of a circle, we can  write this as:

A=[tex]\frac{1}{2}[/tex](3.14(r²))

Our radius is a straight line going from the edge of the circle to the center. We have the diameter, which is just the radius doubled (because it goes from the edge to the center point then back to the edge). So, we divide our diameter by 2 to get our radius.

14÷2=7

Our radius is 7, so we can plug that into our equation:

A=[tex]\frac{1}{2}[/tex](3.14(7²))

Now all we have to do, is solve:

A=[tex]\frac{1}{2}[/tex](3.14(49))

A=[tex]\frac{1}{2}[/tex](153.86)

A=76.93

So, our area is 76.93 units².

Answer:

D

Step-by-step explanation:

|x+1|>2

-2>x+1>2

-3>x>1

Option D is correct that is the solution of the inequality |x+1|>2 is  x<-3 or x<1.

A statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions.

Solution of an inequality is a value that makes the inequality true.

According to the given question

We have an inequality |x + 1|>2.

The solution set of the above inequality is given by

[tex]|x + 1| > 2[/tex]

⇒ [tex]-2 > x+1 > 2[/tex]

⇒ [tex]-2-1 > x > 2-1[/tex]

⇒ [tex]-3 > x > 1[/tex]

⇒ [tex]x < -3[/tex] or [tex]x < 1[/tex]

Answer:

Area of a triangle

Step-by-step explanation:

1/2bh is used to find the area for a triangle

Step-by-step explanation:

12=-4(-6x-3)

when minus is multiplied by minus then the result is plus,

12=24x+12

Now, subtract 12 from both sides,

12-12=24x+12-12

0=24x

Now, divide both sides by 24

0/24=24x/24

0=x

Answer and Step-by-step explanation:

First, distribute the negative 4 onto the negative 6x and negative 3.

12 = 24x + 12

Subtract 12 from both sides of the equation.

0 = 24x

Divide both sides of the equation by 24.

x = 0

To check our answer:

-4(-6(0) - 3) = 12

-4(0 - 3) = 12

-4(-3) = 12

12 = 12 ✓

So, x is equal to 0.
