using both functions, determine which company is a better value for a 5 mile ride. show your work.

what are some real world limitations to the domain and range of both functions?​

Answer:

x-1

Step-by-step explanation:

The solution to the equation 21 = 14 + 7x is x = 1.

Given the equation in the question:

21 = 14 + 7x

To solve the equation 21 = 14 + 7x, start by isolating the variable x to one side of the equation:

21 = 14 + 7x

Subtract 14 from both sides of the equation:

21 - 14 = 14 - 14 + 7x

Add 14 and -14:

21 - 14 = 7x

Subtract 14 from 21:

7 = 7x

Reorder the equation:

7x = 7

Divide both sides by 7:

7x/7 = 7/7

x = 7/7

x = 1

Therefore, the value of x is 1.

Answer:

teo= 15 years old

richard= 27 years old

Step-by-step explanation:

richard=r

teo=t

r + t=42

t + 12= r

u can use substitution here  

(t+12) + t=42

2t + 12= 42

2t=30

t= 15

to find r, you just do 15 + 12= 27

to check you can do 27 + 15= 42

The age of Richard and Teo will be 27 years and 15 years, respectively.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

Richard and Teo are 42 years old. Richard is 12 years older than Teo.

Let x be the age of Richard and y be the age of Teo. Then the equation is given as,

x + y = 42         ...1

x = y + 12         ...2

From equations 1 and 2, then we have

y + 12 + y = 42

2y = 30

y = 15

Then the value of the variable 'x' is given as,

x = 15 + 12

x = 27

The age of Richard and Teo will be 27 years and 15 years, respectively.

Answer:

10%

Step-by-step explanation:

Price of computer = $750

Amount of sales tax = $75

Sales tax rate = Amount of sales tax / Price of computer × 100

= $75 / $750 × 100

= 0.1 × 100

= 10%

Sales tax rate = 10%

Sales tax rate = 10% of selling price

Answer:

  see attached

Step-by-step explanation:

The scale of the drawing is 50 m per grid square.

The magnitude of the resultant can be found using the Pythagorean theorem:

  r = √(n² +e²)

  r = √(500² +200²) = 100√29 ≈ 538.52 . . . meters

__

The direction angle can be found using the arctangent function.

The angle east of north is ...

  arctan(200/500) ≈ 21.8014°

The resultant is 538.52 meters in the direction 21.8° east of north.

Answer/Step-by-step explanation:

There are 81 Alligators.

The original equation was 5:9. Since the 5 turtles have been scaled up(multiplied by) 9 times. The rate for alligator will be multiplied by 9.

45 ÷ 5 = 9

9 x 9 = 81

5:9 x 9 = 45:81

Answer:

The corect answer is 16.

Step-by-step explanation:

Answer: It will take 15 weeks for Cyndi and her sister to have the same amount of money.

Step-by-step explanation:

Given: Cyndi has $55. Her sister has $115.

Cyndi saves $10 per week. Her sister saves $6 per week.

Let x= Number of weeks.

Total amount of money Cyndi has = 55+10x            (i)

Total amount of money sister has = 115+6x              (ii)

From (i) and (ii) , we get

[tex]55+10x=115+6x\\\\\Rightarrow\ 10x-6x=115-55\\\\\Rightarrow\ 4x=60\\\\\Rightarrow\ x=\dfrac{60}{4}\\\\\Rightarrow\ x=15[/tex]

Hence, it will take 15 weeks for Cyndi and her sister to have the same amount of money.

Answer:

A,-7

B, 4

C,13

D,2

Step-by-step explanation:

A,Step 1: Divide both sides by 4.

[tex] \frac{4x}{4} = \frac{ - 28}{4} [/tex]

[tex] x = - 7[/tex]

B,Step 1: Add 6 to both sides.

x−6+6=−2+6

x = 4

C, Step 1: Regroup terms.

4−Y=−9

Step 2: Subtract 44 from both sides.

-Y=-9-4−Y=−9−4

Step 3:Simplify -9-4−9−4 to -13−13.

[tex] \frac{ - y}{1} = \frac{ - 13}{ - 1} [/tex]

Y = 13

D,Subtract 77 from both sides.

-3x=1-7−3x=1−7

2, Simplify 1-71−7 to -6−6.

-3x=-6−3x=−6

3,Divide both sides by −3.

[tex] x = \frac{ - 6}{ - 3} [/tex]

4,Two negatives make a positive.

x = 6/3

x = 2.
