Mario paid $44in taxi fare from the hotel to the airport. the cab charged $2 for the first mile plus $3 for each additional mile. how many miles was it from the hotel to the airport

Answer:

5x^3-2

Step-by-step explanation:

Two less than the product of 5 and the cube of a number.

The product of 5 and the cube of a number can be translated to look like 5x^3.

You then take 5x^3 and subtract 2 to get 5x^3-2.

Step-by-step explanation:

14x + 5 = 12

14x = 12 - 5

14x = 7

x = 7/14

x = 1/2

♧ So, after 3 years = x+81 +3

♧ now grouping the variables and constants together we get,

♧ Thus, Victor's present age is 24 yrs.

Hope it helps ya ~

Answer:

Victor's age = 24 years old

Step-by-step explanation:

Let age of Mr. Smith = x and age of Victor = y.

According to the question, we can find two equations.

=> 1) x = y + 81

=> 2) x + 3 = 4(y + 3)

Substituting value of x in (1) to (2)

y + 81 + 3 = 4y + 12

3y = 72

y = 24

Victor's age = 24 years old

Answer: Faith's printing account balance will become $-1.90, or $1.90 below 0.

Step-by-step explanation:

Each sheet of paper can print 4 pages. Since it is 47 pages long, she will need 12 pages. That will cost 3 dollars, since 0.25x12=3. 1.10-3=-1.90 dollars, which means that she is $1.90 in debt.

x es igual a 6.4

Answer:

The answer is A)

Step-by-step explanation:

To find out table contains a set of points that lie in the graph of this function , we have to hit and trial method ,

when we put the value of x in y = –2x + 3 this equation so ,

taking x = 1 , then the value of y is

=> y = -2(1)+3

=> y = -2+3

=> y = 1

taking x = 0 , then the value of y is

=> y = -2(0)+3

=> y = 3

now talking x = -3 , then the value of y is

=> y = -2(-3) +3

=> y = 6+3

=> y = 9

so , the option A is the right answer

Answer:

A)

Step-by-step explanation:

Given linear function:  y = -2x + 3

Therefore, the slope is -2 and the y-intercept is (0, 3)

Therefore, we are looking for a set of ordered pairs that has a rate of change of -2

⇒ as the x-value increases by 1 unit, the y-value decreases by 2 units

i.e. as the x-value decreases by 1 unit, the y-value increases by 2 units.

The only set of ordered pairs that follows this rule is A)

Let's check by substituting the values of x = 1, x = 0 and x = -3 into the function:

when x = 1 → -2(1) + 3 = 1

when x = 0 → -2(0) + 3 = 3

when x = -3 → -2(-3) + 3 = 9

Confirming that the set of ordered pairs in A) lie on the graph of the given function.

Answer:

Yes, he is correct, 240 miles will require a gas volume of 13.71 gallons which is less than 15 gallons in  Enrique's car.

Step-by-step explanation:

Given;

total volume of gas in Enrique's car, V = 15 gallons

The rate of gas consumption [tex]= \frac{35 \ miles}{2 \ gallons} = 17.5 \ miles/gallon[/tex]

To drive 240 miles, he would need the following volume of gas;

[tex]V = 240 \ miles* \frac{1}{\frac{17.5 \ miles}{gallon} }\\\\ V = 240 \ miles*\frac{1*gallon}{17.5 \ miles}\\\\ V = (\frac{240 \ miles}{17.5 \ miles} )gallon\\\\V = 13.71 \ gallons[/tex]

The volume of gas needed to drive 240 miles is less than the total volume of gas in Enrique's car.

Thus, he is correct

Answer:

D)

Step-by-step explanation:

4 is an evident zero of the equation x^3 - 64.

x^3 - 64 can only be factorized with (x-4) and not with (x+4)

because x - 4 = 0 <==> x = 4 and 4^3 -64 = 0

Developing B) would be:

x^3 + 4x^3 + 16x - 4x^2 - 16x - 64 = 5x^3 - 4x^2 -64

So it doesn't match so it's D)

Since both angles will be a part of triangle, and the third angle would be 90° as, the vertices meet at an centre of diagonal, hence they bisect each other.

7x-12 +(10x+5) = 90°

==> 17x -7= 90°

==> 17x = 97°

==> x = 97°/17

==> x = 5.70° (approx)

Given parameters:

 The coordinates are:

                 P1 (8, -4) and P2 (-3, 9)

Unknown:

The midpoint of the endpoints = ?

Solution:

     x₁  =  8

     y₁  = -4

     x₂  = -3

     y₂  = 9

  midpoints;     x[tex]_{m}[/tex] , y[tex]_{m}[/tex]  = [tex]\frac{x_{1} + x_{2} }{2} ,[/tex] [tex]\frac{y_{1} + y_{2} }{2}[/tex]

                                       = [tex]\frac{8 +(-3)}{2}[/tex] , [tex]\frac{-4 + 9}{2}[/tex]

                                       = [tex]\frac{5}{2}[/tex] , [tex]\frac{5}{2}[/tex]

   The coordinate of the x-axis is [tex]\frac{5}{2}[/tex]

Step-by-step explanation:

Answer:

$486 (Paul)

$243(Brian)

$81(Colin)

Solving steps:

let Paul Be x, Brian be x,Colin be x

since Paul got twice as much as Brian which shows that brian and got three times

So Paul,= 3×2 so he got six times as much as the two others

while Brian got three times

and colins got once

so let's make an equation for this problem

=> 6x + 3x + x = $810

add 6 x + 3 x + x which give you 10 x

=> 10x = $810

divide both side by the coefficient of x

=> [tex] \frac{10x}{10} = \frac{810}{10} [/tex]

=> [tex]x = \frac{810}{10} [/tex]

=> x = 81

since you we have find what the value of x

insert into the previous equation which is

=> 6x + 3x + x

=> 6(81) = $486-----(for Paul)

3(81) = $243-------(for Brian)

(81) = $81 ---------(for Collin)

Step-by-step explanation:

Scientific notation is a way of expressing numbers that are too large or too small.

To figure out the power of 10, think "how many places do I move the decimal point?"

1. When the number is 10 or greater, the decimal point has to move to the left, and the power of 10 is positive.

2. When the number is smaller than 1, the decimal point has to move to the right, so the power of 10 is negative.

Answer:

Step-by-step explanation:

On the first day, Ben (B) starts with 10 tubs and Winston (W) starts with 0 tubs.

After the first day, Ben sells 8 tubs per day while Winston sells 9 tubs per day.

Therefore we can write the following equation:  (Where d = number of days)

B = 10 + 8d

W = 0 + 9d = 9d

We are told that eventually they will sell the same amount which means

B = W

This means we can say,

10 + 8d = 9d

If we subtract 8d from both sides we get

10 = d

Therefore it will take 10 days for them to sell the same amount of cookie dough.

Answer: 10 days

10 + 8 x 10 = 90

9 x 10 = 90.

It will take 10 days for Ben and Winston to sell the same amount of cookie dough.

How many times must one "base" number be multiplied by itself in order to generate another specific number? The answer is found using a logarithm (or log).

For instance, how many times must a base of 10 be multiplied by itself to get 1,000? The answer is 3 (1,000 = 10 × 10 × 10).

Given that;

We have to use the property as;

aᵇ = x then

b = logₐx

So, we get;

log₁₂ 144 = a

12ᵃ = 144

12ᵃ = 12²

On comparing the base

= 2

Now,  second is,

log₁₅ 1 = a

15ᵃ = 1

a = 0

Now, log₃ (1/81)

3ᵃ = 1/81

3ᵃ = 3⁻⁴

a = - 4

And, log 0.00001

= log (10)⁻⁵

= -5 log 10

= -5
