When the football play started,
Tony ran forward 20 yards,
then turned around and ran 5 yards back.
He stood in that spot for 3 seconds,
then walked back to where he began.

Answer:

=2x+4c+17

Step-by-step explanation:

(2x-3)+(4c+20)

=2x-3+4c+20

=2x+4c-3+20

=2x+4c+17

$100 - $20 = $80

3 / 5 (three - fifths)

Step-by-step explanation:

6 / 10 =

Divide both the top and bottom by 2.

3 / 5

Because 3 and 5 are prime numbers (5 can only be divided by 1 and 5, and 3 can only be divided by 1 and 3), this is the most simplified form.

Step-by-step explanation:

2(2x + 3y)=4x+6y

4x+6y=4x+6y

4x+6y-6y=4x+6y-6y

4x=4x

Answer:

8miles

Step-by-step explanation:

If Brian jogged 2 miles in 30 minutes, this is expressed as;

2miles = 30minutes

To calculate the distance covered in 2hrs, we can say

x miles = 2hrs (120minutes)

Divide both expressions

2/x = 30/120

Cross multiply

30x = 2 * 120

30x = 240

x = 240/30

x = 8

hence he covers 8miles in 2hrs

Answer:

x = 9

Step-by-step explanation:

If g(x) = 3, that means that the output is three.

Outputs are y values.

Look at the graph. When y=3, the x  = 9.

So the input value for which g(x) = 3 (aka that gives the output y = 3) is x = 9

Answer:

square root function is the correct answer

The solution is,  y = 2 ^ (x + 2) +3, is the function is shown in the graph below.

In mathematics, the graph of a function f is the set of ordered pairs, where {\displaystyle f(x)=y.} In the common case where x and f(x) are real numbers, these pairs are Cartesian coordinates of points in two-dimensional space and thus form a subset of this plane.

here, we have,

For this case we observe the cut point with the y axis in:

(0, 7)

The function that complies with this is:

y = 2 ^ (x + 2) +3

We have then:

y = 2 ^ (0 + 2) +3

y = 2 ^ (2) +3

y = 4 + 3

y = 7

Answer:

The answer for this case is given by:

y = 2 ^ (x + 2) +3

option 2

Hence, The solution is,  y = 2 ^ (x + 2) +3, is the function is shown in the graph below.

Answer:

Greg spent 9.49 cents on the book

The cost of one book is A = $ 9.49

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

Let the cost of 5 books be = $ 47.45

Now , the cost of one book is A

where A = 47.45 / 5

On simplifying the equation , we get

A = $ 9.49

Hence , the cost is A = $ 9.49

Answer:

Below.

Step-by-step explanation:

Prove that if

a^x = b^y = (ab)^(xy)  then x + y = 1.

From the second equation:  

y = 1 - x

So we have:

a^x = b^y = b^(1-x)  

Taking logs:

x ln a = (1-x)ln b

x ln a + x ln b = ln b

x = ln b / ( ln a + ln b)

x = ln b / ln ab.

This is true if x + y = 1.

Now consider b^y = (ab)^(xy):

b^(1 - x) = (ab)^(x(1- x)

ln b - x ln b = x(1 - x)ln ab

ln b - x ln b = x ln ab - x^2 ln ab

Now we substitute for x = ln b / ln ab in this expression.

If left side = right side then we have proved this identity and therefore the original one.

Left side =  ln b - (ln b / ln ab) * ln b =  ln b - (ln b)^2 / ln ab.

Right side = (ln b / ln ab) * ln ab - [(ln b)^2 / (ln ab)^2] * ln ab

=    ln b - (ln b)^2 / ln ab.

Left side = right side so this identity is true, and so the original one

( x + y = 1) is true also.

Answer:

0.105 = 10.5% probability that an accident results in a death.

Step-by-step explanation:

What is the probability that an accident results in a death?

5% of 60%(sunny)

25% of 20%(foggy)

12.5% of 20%(rainy)

So

[tex]p = 0.05*0.6 + 0.25*0.2 + 0.125*0.2 = 0.105[/tex]

0.105 = 10.5% probability that an accident results in a death.

The probability that an accident results in a death is 0.105 = 10.5%

Given :

25% of accidents in foggy conditions result in death.

12.5% of accidents in rainy conditions result in death

5% of accidents in sunny conditions result in death

"Probability"

The probability that an accident results in a death

Probability =0.05*0.6+0.25*0.2+0.125*0.2

Probability =0.105

Probability =10.5%

The probability that an accident results in a death is 10.5%.
