Answer:

20 miles $80

Step-by-step explanation:

20 miles

P%5Bc%5D%2820%29=20%2B3%2820%29=20%2B60=80

$80

Answer:

M=Main buses

C=Country buses

Step-by-step explanation:

so the charges from Main are $40 fee, then additional $2 for every mile you drive it for, so M = 40 + 2m

if your mileage is 20miles, when 2*20 is the charge

if your mileage is 50miles, when 2*50 is the charge

if your mileage is 1000miles, when 2*1000 is the charge

if your mileage is "m" miles, when 2*m is the charge

and County charges are $20 fee, then additional $3 for every mile... .so then C = 20 + 3m

if your mileage is 20miles, when 3*20 is the charge

if your mileage is 50miles, when 3*50 is the charge

if your mileage is 1000miles, when 3*1000 is the charge

if your mileage is "m" miles, when 3*m is the charge

so, their total charge is M and C respectively

when are the charges equal? well, when M = C

or

40 + 2m = 20 + 3m

solve for "m", to see at how many miles that happens

what will the charge be? plug that value for "m" on either, to get the charge

Answer:

6.02, 6.45, 6 1/2

Step-by-step explanation:

Answer:

Step-by-step explanation:18x−2(3x+1)=5x−16

18x+(−2)(3x)+(−2)(1)=5x+−16

18x+−6x+−2=5x+−16

(18x+−6x)+(−2)=5x−16

12x+−2=5x−16

12x−2=5x−16

Step 2: Subtract 5x from both sides.

12x−2−5x=5x−16−5x

7x−2=−16

Step 3: Add 2 to both sides.

7x−2+2=−16+2

7x=−14

Step 4: Divide both sides by 7.

Answer:

you multiply what you want to be a percentage divide it by 100

Answer:

Just multiply the number that you want to take a percent of by the decimal version of that percent for example;

24% of 70

70 x .24 = 16.8

24% of 70 is 16.8

Answer:

1:2

Step-by-step explanation:

In total, there are 800 coins. 400 of those coins are pennies. The ratio is 400 pennies to 800 coins. Since 400 is half of 800, this can be simplified down to 1 penny to 2 coins, or 1:2.

Step-by-step explanation:

Answer:

10

Step-by-step explanation:

Given that:

Point X = (3, 2)

Point Y = (3, - 8)

Distance of point X to Y:

Distance = √(x2 - x1)^2 + (y2 - y1)^2

X1 = 3 ; y1 = 2 ; x2 = 3 ; y2 = - 8

Distance = √(3 - 3)^2 + (-8 - 2)

Distance = √(0)^2 + (-10)^2

Distance = √0 + 100

Distance = √100

Distance = 10

Answer:

B. 4+3s

Step-by-step explanation:

The expression that represents the number of seeds that has been planted by Israel is 4 + 3s. Hence, Option B is correct.

A finite combination of symbols that are well-formed in accordance with context-dependent principles is referred to as an expression or mathematical expression in mathematics.

Mathematical symbols can represent variables, operations, functions, brackets, punctuation, and grouping to help specify the logical syntax and order of operations.

But in contemporary mathematics, and particularly in computer algebra, formulae are seen as expressions that can be evaluated as true or false, depending on the values given to the variables present in the expressions.

In the garden, Israel sowed 4 tomato seeds. Then Israel scattered flower seeds throughout the gardens of the three neighbors. Here neighbors will be denoted as x. For this the most suitable expression will be 4 + 3s.

Therefore, Option B is correct.

Answer:

[tex]f^{-1}(x)=\sqrt{x+16}[/tex]

Step-by-step explanation:

[tex]f(x)=x^2-16[/tex]

The inverse of the function [tex]f[/tex] is [tex]f^{-1}[/tex]

The Range of the inverse function [tex]f[/tex] will be the Domain of the function [tex]f[/tex]

[tex]Ran(f^{-1}) = [0, \infty)[/tex]

The inverse of

[tex]f(x)=x^2-16[/tex]

is

[tex]f^{-1}(x)=\sqrt{x+16}[/tex]

Note that if the domain of the function [tex]f[/tex] where all the Real numbers, the inverse would be

[tex]f^{-1}(x)=\pm\sqrt{x+16}[/tex]

Answer:

Inverse of [tex]f(x)=x^2-16[/tex] is [tex]f^{-1}(x)=\sqrt{x+16}[/tex]

Option A is correct option.

Step-by-step explanation:

We need to find inverse of [tex]f(x)=x^2-16[/tex]

For finding inverse replace f(x) with y

[tex]y=x^2-16[/tex]

Now, solve for x

Adding 16 on both sides

[tex]y+16=x^2-16+16\\y+16=x^2\\=> x^2=y+16[/tex]

Taking square root on both sides:

[tex]x^2=y+16\\\sqrt{x^2} =\sqrt{y+16} \\x=\sqrt{y+16}[/tex]

Now replace x with f^{-1}(x) and y with x

[tex]f^{-1}(x)=\sqrt{x+16}[/tex]

So, inverse of [tex]f(x)=x^2-16[/tex] is [tex]f^{-1}(x)=\sqrt{x+16}[/tex]

Option A is correct option.
