Answer:

10 times

Step-by-step explanation:

Let x be the amount of times you go to the gym

Option A would be 20+2x

Option B would be 4x


now the question is after how many trips would the cost be the same?


20+2x=4x

Solve the equation so

20=4x-2x

20=2x

X=10

It would take 10 times for the cost to be the same for both options

il63 [147K]

Answer:

Option C.

Step-by-step explanation:

Note: The question and options are  not in correct form.

Let the correct question is "Consider the formula for the average velocity, v, of a moving particle. In the formula, d1 and d2 represent the distance traveled by the particle at times t1 and t2 respectively.

v = (d2 - d1)/(t2 - t1)  

Which of the following equations is equivalent to the formula for velocity?

A. t1=v(d2-d1)-t2

B. d1=v (t2-t1)-d2

C. d2=v(t2-t1)+d1

D. t2=v(d2-d1)+t1 "

The given formula is  

v=\dfrac{d_2-d_1}{t_2-t_1}

On cross multiplication, we get

v(t_2-t_1)=d_2-d_1

Add d_1 on both sides.

v(t_2-t_1)+d_1=d_2-d_1+d_1

v(t_2-t_1)+d_1=d_2

Since, d_2=v(t_2-t_1)+d_1, therefore, the correct option is C.

What is the slope of (3,-20),(5,8)
fomenos
The equation for slope is <u>y² - y
</u>                                        x² - x

So it would be:                <u>8 - (-20)</u>   or    <u>8 + 20
</u>                                          5 - 3               5 - 3 

<u>28</u>
 2

Then, you have to reduce it, divide both by two.
 
 <u>14</u>
  1

Since it is over 1, then it is just the numerator.

Your final is:
<em>Slope = 14</em>

HURRYYYYYYYYY <br><br><br> What is the domain of the function y=x?<br> -00 0 0 0 1
Svetach [21]

Answer:

All real numbers

Step-by-step explanation:

The domain of the function is the set of real values that can be substituted into a function to produce a valid output. Any real number can be substituted into the function (y = x), and produce a valid output. Thus, the domain is all real numbers.

The distribution of actual weights of 8-ounce wedges of cheddar cheese produced at a dairy is normal with mean 8.1 ounces and st
Brrunno [24]
The mean of the weight is 8.1 ounces. 
So the means of the distribution of 10 sample will be 10*8.1.
And the mean of 20 <span>cheese wedges is again 20*8.1. 
(The mean of the addition of two normal law is the sum of the 
mean of each law)
Divide the above two numbers: </span>\frac{20\times8.1}{10\times8.1}=2

The distribution of the sample means of the weights of cheese wedges is multiplied by 2 in the new <span>batches</span>.
