Answer:

136 miles

Step-by-step explanation:

Write an equation to represent the cost of the rental, and then solve the equation to find the number of miles.

Let x = number of miles.

The total cost is the cost per mile plus the base fee.

1 mile costs $0.90

2 miles cost $0.90 * 2

x miles cost $0.90 * x, or simply 0.9x

The base fee is $16.95, so the total to rent for x miles is 0.9x + 16.95

The equation

c = 0.9x + 16.95

gives you the cost, c, for a rental of x miles.

We are told the total cost was $139.35. Replace c with 139.35, and solve for x, the number of miles.

139.35 = 0.9x + 16.95

Switch sides.  

0.9x + 16.95 = 139.35

Subtract 16.95 from both sides.

0.9x = 122.4

Divide both sides by 0.9

x = 122.4/0.9

x = 136

Answer: 136 miles

Answer:

15 m and 20 m

Step-by-step explanation:

Let the width be x

Length = x + 5

Perimeter = 2(l + b)

70 = 2(x + 5 + x)

70/2 = 2x + 5

35 = 2x + 5

35 - 5 = 2x

30 = 2x

30/2 = x

15 = x

Length = x + 5 = 20 m

Breadth = x = 15 m

Answer:

y=95

Step-by-step explanation:

17x5=85

180-85=95

y=95

Each of the pairs of opposite angles made by two intersecting lines is called a pair of vertical angles. The value of x and y is 17 and 95, respectively.

Each of the pairs of opposite angles made by two intersecting lines is called a pair of vertical angles.

The measure of ∠1 and ∠3 will be equal since the two angles are vertical angles. Therefore, we can write.

∠1 = ∠3

5x° = 85°

x = 85° / 5

x = 17°

Also, the sum of measures ∠1 and ∠2 will be equal to 180°, this is because the two angles form a pair of linear angles. Therefore, we can write,

∠1 + ∠2 = 180°

5x + y = 180°

Substitute the value of x,

5(17°) + y = 180°

85° + y = 180°

y = 180° - 85°

y = 95°

Hence, the value of x and y is 17 and 95, respectively.

AC = [tex]\sqrt{58}[/tex]

Step-by-step explanation:

Calculate AC using the distance formula

d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = A (0, - 2) and (x₂, y₂ ) = C (3, 5 )

AC = [tex]\sqrt{(3-0)^2+(5-(-2)})^2[/tex]

     = [tex]\sqrt{3^2+(5+2)^2}[/tex]

    = [tex]\sqrt{9+7^2}[/tex]

    = [tex]\sqrt{9+49}[/tex]

    = [tex]\sqrt{58}[/tex]

let the last number be x

we know,

[tex] \boxed{mean = \frac{sum \: \: of \: \: all \: \: observations}{number \: \: of \: \: observations} }[/tex]

So,

[tex] \hookrightarrow \: 8 = \dfrac{22 + x}{4} [/tex]

[tex] \hookrightarrow \: 8 \times 4 = 22 + x[/tex]

[tex] \hookrightarrow \: 32 = 22 + x[/tex]

[tex] \hookrightarrow \: x = 32 - 22[/tex]

[tex] \hookrightarrow \: x = 10[/tex]

therefore, the last number is 10.

Answer:

[tex]y = \frac{3}{2} x + 2[/tex]

Step-by-step explanation:

In the slope-intercept form y= mx +b, m is the slope and b is the y- intercept.

[tex]\boxed{slope = \frac{y1 - y2}{x1 - x2} } [/tex]

Using the formula above,

[tex]slope = \frac{5 - ( - 4)}{2 - ( - 4)} [/tex]

[tex]m = \frac{5 + 4}{2 + 4} [/tex]

[tex]m = \frac{9}{6} [/tex]

[tex]m = \frac{3}{2} [/tex]

Substitute the value of m into the equation:

[tex]y = \frac{3}{2} x + b[/tex]

To find the value of b, substitute a pair of coordinates into the equation.

When x= 2, y= 5,

[tex]5 = \frac{3}{2} (2) + b[/tex]

5= 3 +b

b= 5 -3

b= 2

Thus, the equation of the line is [tex]y = \frac{3}{2} x + 2[/tex].

y = -5/4 - 31/5

Step-by-step explanation:

A: (-1,-7) and B: (9,1)

Slope: (-7-1)/(-1-9) = -8/-10 = 4/5

Slope: 4/5. Point (9,1)

y-1 = 4/5 (x-9)

y-1 = 4/5x - 36/5

y = 4/5x - 36/5 + 1

y = 4/5x - 31/5

Perpendicular bisector = Y = - 5/4x - 31/5

Answer:

-3/8

Step-by-step explanation:

8y = 4 - 3x

~Divide 8 to everything

y = 1/2 - 3/8x

~Reorder

y = -3/8x + 1/2

In slope intercept form [ y = mx + b ] m resembles the slope so -3/8 is the slope.

8) v = -3

9) m = 4

Explanation:

8)

[First distribute the factored terms on the left side of the equation]

2(v + 4) + 3(4v + 5) = -19 →

2(v) + 2(4) + 3(4v) + 3(5) = -19 →

2v + 8 + 12v + 15 = -19 →

[Next, add the like terms together]

(2v + 12v) + (8 + 15) = -19 →

14v + 23 = -19 →

[Subtract 23 from both sides to isolate the constant term]

14v + 23 – 23 = -19 – 23 →

14v = -42 →

[Lastly, divide both sides by 14 in order to obtain the value of v from the coefficient of 14 in 14v]

14v / 14 = -42 / 14 →

v = -3

9)

[Start by distributing the factored term on the left side of the equation]

2(m – 1) = 10 – m →

2m – 2 = 10 – m →

[Next, add m to both sides in order to isolate the m term and remove -m from the right side of the equation]

2m – 2 + m = 10 – m + m →

3m – 2 = 10 →

[Add 2 to both sides to isolate the constant term and remove -2 on the left side of the equation]

3m – 2 + 2 = 10 + 2 →

3m = 12 →

[Finally, divide by 3 on both sides in order to reduce the coefficient of 3 in 3m to get m]

3m / 3 = 12 / 3 →

m = 4

A is true: 1 > 0, and f (1) = 1² - 1 = 0.

B is false: -2 < 0, so f (-2) = -(-2) + 1 = 3.

C is false: 4 > 0, and f (4) = 4² - 1 = 15.

D is true: -1 < 0, so f (-1) = -(-1) + 1 = 2.

Objective; Translating points

A translation is when we moving figures and points. We can represent a transformation algebraically and geometrically.

Algebracially:

[tex](x + h)[/tex]

where h is the amount of units we move right or left

and

[tex](y + k)[/tex]

where k is the amount of units we move up or down

For 1. We are asked to translate the figure 3 units up and 7 units to the left.

7 units to the left is the same as subtracting 7 . from x valyes. and 3 units up is is same as adding 3 units to the y values, so subtract 7 from every x coovalues. and add 3 to every y value. is

Our new coordinates

E is (-5,3) F is (-2,4) G is (-3,5) H is (-5,5).

2. 6 units right and 8 units up is basically add 6 to every x value and add 8 to every y value.

So our new coordinates is

U' (4,3)

V'(4,5)

W'(1,5)

The expression for another number will be 25 - x.

An expression is a combination of some mathematical symbol such that arithmetic operator and variable such that all are constrained and create an equation.

In other meaning, expression is very useful to determine the end or root value of constraint.

For example 3x +5y

The constraint of expression is represented as = or <, >.
