A cab company charges $7 boarding fee in addition to its meter which is $4 for every mile. The equation of the line that represents this cab company's rate is:
a. y = 4x + 7
b. y = 7x + 4
c. y = 4x - 7
d. y = 4x + 6 ​

So you know that all the angles in a triangle must add up to 180. Therefore, you can make this equation:

[tex](-20x+3)+(-40x+18)+(-15x+9)=180[/tex]

And now just solve for x!

[tex]-75x+30=180\\-75x=160\\x=\frac{160}{-75}\\x=-2.4[/tex]

So, your answer is:

x = -2.4

Answer:

(x - 7)(x - 4)(x + 4).            

Step-by-step explanation:

A(x) = x3 – 7x² – 16x +112

Dividing by x-7:

      x^2  - 16               <-------- Quotient

     -----------------------------

x-7)x^3 - 7x^2 - 16x + 112

     x^3 - 7x^2

                    0 - 16x + 112

                        - 16x + 112

                          ..............

so A(x) = (x - 7)(x^2 - 16)       x^2 - 16 is the difference of 2 squares so we have:

(x - 7)(x - 4)(x + 4).

Checking by expanding the brackets:  

(x - 7)(x - 4)(x + 4)

= x(x - 4)(x + 4) - 7(x - 4)(x + 4)

= x(x^2 - 16) - 7(x^2 - 16)

= x^3 - 16x - 7x^2 + 114

= x^3 - 7x^2 - 16x + 112          

Answer:

a) linear, straight when graphed and no exponents

b) quadratic, x has exponent

c) quadratic, x has exponent

d) linear, no exponent

e) quadratic, x has exponent

f) i think it's neither because there's two variables that can't add together

Step-by-step explanation:

Answer:

A is linear because a linear equation is mapped in the form y=ax+b and results in a straight line when graphed. This equation has a slope, 1, which occupies the space for a and a y-intercept of 3 which occupies the space for b

B is neither because it doesn't fit the linear form or the quadratic form (which is constrained by the equation y=ax^2+bx+c. The highest degree for this form is 2.) I believe this function is actually a type of cubic which is not an option for the question.

C is a quadratic because it follows the form y=ax^2+bx+c and results in a parabola

d. 3x-y=5 is linear because even though it is not in the y=ax+b form, it can be manipulated into it by subtracting 3x from both sides and then dividing by -1 on both sides to get y=3x-5 which fits the form and graphs a line.

e. 5-x^2=89 would be neither because there is only one variable and there is no value of y that can be solved for. While we can find an x value (or perhaps multiple x values depending on the equation) it wouldn't result in a graphable equation which is a necessity to be classified as a linear or quadratic. In fact, I believe this is actually just an equation and not a function at all and since linear and quadratics are forms of functions they cannot be either. This is because a function is defined as a relation between two variables where each input has one (and only one) output and this equation doesn't have two variables and wouldn't have an output.

f. Neither for the same reason as in e

Hope this helps!

The solution to the equation [tex]\frac{-4}{1(a-4)} = \frac{4}{7(a-3)}[/tex] is a = 3.125

The given equation is:

[tex]\frac{-4}{1(a-4)} = \frac{4}{7(a-3)}[/tex]

Cross multiply:

[tex]-4(7)(a-3) = 4(a-4)[/tex]

Divide both sides by 4

[tex]\frac{-4(7)(a-3)}{4} = \frac{4(a-4)}{4} \\-7(a-3) = a - 4[/tex]

Expand the bracket using the distributive rule

-7a + 21  =  a  -  4

Collect like terms

a  +  7a   =  21  +  4

Simplify the arithmetic

8a   =  25

Divide both sides by 8

[tex]\frac{8a}{8} = \frac{25}{8}\\a = \frac{25}{8}\\a = 3.125[/tex]

Answer:

0.3

Step-by-step explanation:

Percent means 'per 100'. So, 30% means 30 per 100 or simply 30/100. If you divide 30 by 100, you get 0.3 (a decimal number). So, to convert from percent to decimal, simply divide by 100 and remove the '%' sign. There is a easy way to convert from percent to decimal: Just move the decimal point 2 places to the left.

Answer:

correct the answer is 6.13

Step-by-step explanation:

The required current balance in Maggie's bank account is 6.13.

Given that,
Maggie has a bank account balance of -18.37 as soon as she realizes this she deposits 24.50 in the account.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

here,
initial balance in Maggies's bank account = -18.37
She deposited 24.50 in her bank account,
The current balance in her bank account = Initial balance + money deposited
Current = 24.50 - 18.37
Current balance = 6.13

Thus, the required current balance in Maggie's bank account is 6.13.

Step-by-step explanation:

let the 3 consecutive odd number be

x + 1 , x + 3 , x + 5

as, there sum is 45. so, after inserting the values we got,

→ x + x + 1 + x + 3 = 45

→ 3x + 9 = 45

→ 3x = 45 - 9 = 36

→ x = 36/3 = 12

→ x = 12

therefore, 3 consecutive odd number are

→ x + 1 = 12 + 1 = 13

→ x + 3 = 12 + 3 = 15

→ x + 5 = 12 + 5 = 17

Answer:

the following ordered pairs are your coordinates: (-3,-10), (-1, -4), (0,-1), (4,11)

Step-by-step explanation:

We can find these algebraically. First, you need to put your equation into the form y=mx+b. The m is the slope and the b is your y intercept. Once we have that equation, we just plug in the given X values to find their Y counterparts. The domain is simply the X coordinate and the range is the Y. I hope this helps!

Answer:

Length = 6 + 23 = 29 feet

Step-by-step explanation:

Width = x

Length = x + 23

2x + 2(x+23) = 70

2x + 2x + 46 = 70

4x = 70-46

x = 24/4

x = 6
