Answer:

Step-by-step explanation:

Given the equations:

4c-d = f  ....... 1

d = c-e....... 2

f = d + e....... 3

Substitute 2 into 1

4c -(c-e) = f

4c -c + e =f

3c + e = f ......4

Substitute equation 3 into 4:

3c+e = d+e

subtract e from both sides

3c+e-e = d+e-e

3c = c (Proved)

Answer:

lunch was $20.90

Step-by-step explanation:

Using it's concept, it is found that the domain of the function y = tan(x/8) is given by:

All real numbers except [tex]x \neq 4\pi + 8n\pi[/tex], where n is any integer.

It is the set that contains all possible input values for the function.

Tangent of an angle is sine of the angle divided by the cosine of the angle, and the cosine is 0 at:

[tex]\frac{\pi}{2} + n\pi[/tex]

Hence, supposing a composite tangent function [tex]\tan{[f(x)]}[/tex], the domain is given by:

[tex]f(x) \neq \frac{\pi}{2} + n\pi[/tex]

In this problem, we have that [tex]f(x) = \frac{x}{8}[/tex], hence the domain is:

[tex]\frac{x}{8} \neq \frac{\pi}{2} + n\pi[/tex]

[tex]x \neq 4\pi + 8n\pi[/tex]

All real numbers except [tex]x \neq 4\pi + 8n\pi[/tex], where n is any integer.

Answer:III/ 0.98

Step-by-step explanation: if you multiply a number by a decimal (not like 1.55, since that would increase the value since there is a whole) it will decrease.

Answer:

0.98

Step-by-step explanation:

because if you do 6 x 0.98 you get 5.88

Answer:

The probability  is  [tex]P( p  >  0.585) =  0.044565  [/tex]

Step-by-step explanation:

From the question we are told that

   The population proportion is p =  0.50

   The sample size is n = 100

Gnerally the mean of the sampling distribution is  

          [tex]\mu_x =  0.50[/tex]

Generally the standard deviation of the sampling distribution is  

              [tex]\sigma  =  \sqrt{\frac{p(1- p)}{n} }[/tex]

=>            [tex]\sigma  =  \sqrt{\frac{0.5 (1- 0.5)}{100} }[/tex]

=>            [tex]\sigma  =0.05[/tex]

Generally the approximate probability that the cable company will keep the shopping channel

[tex]P( p  >  0.585) =  P(\frac{p- \mu_{x}}{\sigma }  > \frac{0.585 - 0.50}{0.05} )[/tex]

Generally  [tex]\frac{p- \mu_{x}}{\sigma } = Z (The  \  standardized \  value  \  of  p )[/tex]

=>  [tex]P( p  >  0.585) =  P(Z > 1.7 )[/tex]

From the z-table the probability of  (Z > 1.7 ) is  

       [tex]P(Z > 1.7 ) = 0.044565[/tex]

So [tex]P( p  >  0.585) =  0.044565  [/tex]

Answer:

2y + 2x

Step-by-step explanation:

I assume the question was to simplify/combine

Answer:

83

Step-by-step explanation:

All sides of a triangle combined equal 180 so you would add the values you have and then subtract it from 180

Step-by-step explanation:

We know that:-

All angles of a triangle sum up to give 180°.

So, According to Question,

[tex]20 + 87 + x = 180[/tex]

[tex]107 + x = 180[/tex]

[tex]x = 180 - 107[/tex]

[tex]x = 73[/tex]

So, x = 73° is the answer.

Step 2: Solve for x

Step 3: Check

Plug in x to verify it's a solution.

3(3) - 10 + 4(3) = -2(3 - 4) + 9

9 - 10 + 12 = -2(-1) + 9

Answer:

After 7 weeks from now you will have ​$185 in your bank​ account.

Step-by-step explanation:

We are given that you have ​$70 in your bank account. Each week you plan to deposit ​$7 from your allowance and ​$10 from your paycheck. The equation b = 70 + ​(10 + 7​)w gives the amount b in your account after w weeks.

The equation is given by;

b = 70 + (10 + 7)w

Now, in the question, it is given that you have ​$185 in your bank​ account, that means;

$185 = $70 + $17w

Finding the value of w(weeks);

$17w = $185 - $70

$17w = $115

w = [tex]\frac{\$115}{\$17}[/tex]

w = 6.76 weeks or 7 weeks (approx).

Hence, after 7 weeks from now you will have ​$185 in your bank​ account.

Answer:

When you input 8, the output will be 40

When you input 14, the output will be 9

Step-by-step explanation:

let the function = fn

If    fn < 10,       then output = 5(fn)

If    fn  ≥ 10,   then, Output =  fn - 5

When you input 8 ( 8 is less than 10, then multiply by 5)

fn = 8  and 8 < 10

Output = 5(fn)

Output = 5 x 8

Output = 40

When you input 14 ( 14 is greater than 10, then subtract 5 from the input)

Output = fn - 5

Output = 14 - 5

Output = 9
