18.84

Since the formula of circumference is C = 2 pi r or C = pi times diameter, you can conclude that the circumference is 18.84.

Assuming that pi is 3.14 in this case rather than the full pi or just in terms of pi.

Hope this helps!

What is the solution of -2x-2y=4 and x+5y=10
AysviL [449]
-2x - 2y = 4
x + 5y = 10

It looks like the method it would be easiest to use to solve this system is substitution. To use substitution, let us isolate x in the second equation:

x + 5y = 10
x = -5y + 10

---

-2x - 2y = 4
-2(-5y + 10) - 2y = 4
10y - 20 - 2y = 4
8y - 20 = 4
8y = 24
y = 3

Now we can substitute back into the second equation to find x:

x + 5y = 10
x + 5(3) = 10
x + 15 = 10
x = -5

Finally, to check our work:

-2(-5) - 2(3) = 4   -->   10 - 6 = 4   <--True
-5 + 5(3) = 10   -->   -5 + 15 = 10   <--True

Answer:
y = 3
x = -5

Select the correct answer. For which quotient is x=7 an excluded value?
Lisa [10]

Answer:

\frac{7x}{x^2 - 10x + 21} / \frac{x + 7}{7}

Step-by-step explanation:

Given

See attachment

To answer this question, we start by equating the denominators of each option to 0; then, solve for x

(a):

\frac{7x}{x^2 - 10x + 21} / \frac{x + 7}{7}

This gives

\frac{7x}{x^2 - 10x + 21} * \frac{7}{x + 7}

Set the denominator to 0

(x^2 - 10x + 21)(x + 7) = 0

Solve for x

(x^2 - 7x - 3x + 21)(x + 7) = 0

Factorize:

(x(x - 7) - 3(x - 7))(x + 7) = 0

(x - 7)(x - 3)(x + 7) = 0

This implies that:

x = 7\ or\ x = 3\ or\ x = -7

From above, one of the values of x is 7.

This implies that x = 7 is an excluded value for this quotient.

<em>Other options do not need to be checked, since there is only one answer.</em>

Finding terms of an arithmetic sequence with a recursive formula <br><br>a1 =12 an= an-1+7
Basile [38]

Hey there!!

Recursive formula :

... a( n ) = a ( n - 1 ) + 7

The first term is 12

To find the second term, we will need to substitute 2 in place of ' n '

2 term :

... a( 2 ) = a ( 2 - 1 ) + 7

... a( 2 ) = a( 1 ) + 7

We know a( 1 ) = 12

... a( 2 ) = 12 + 7

... 19 is the second term and we will need to use this to find the other terms.

Hope my answer helps!
