Answer:

20 is the greatest common denominator. You can find this by listing the factors of each number. The highest number that can fit into both individual numbers is the common denominator. Since 40 is just 20 doubled, and 20 is just 20 once, it fits into both numbers and is also the highest number that can fit.

Simplify: x+2/x2-6x-16 ÷ 1/9x
VashaNatasha [74]
\dfrac{x+2}{x^2-6x-16}:\dfrac{1}{9x}=\dfrac{x+2}{x^2-8x+2x-16}\cdot9x=\dfrac{x+2}{x(x-8)+2(x-8)}\cdot9x\\\\=\dfrac{x+2}{(x-8)(x+2)}\cdot9x=\dfrac{1}{x-8}\cdot9x=\dfrac{9x}{x-8}

Vanessa buys a strip of 25 postage stamps the stamps is 21 7/8 inches long how long is it after Vanessa uses on stamp
zloy xaker [14]
To get the answer we have to multiply 25 times 21 7/8. To do that we have to transform 21 7/8 into improper fraction and thn multiply 25 times numerator.
21 \frac{7}{8}= \frac{21*8+7}{8}= \frac{175}{8}
\frac{175}{8}*25 = \frac{175*25}{8}= \frac{4375}{8}=546 \frac{x}{y}  \frac{7}{8} - its the answer

Which statement regarding the function y=sin(x) is true?
REY [17]
<h2>Answer:</h2>

c. Reflection over either the x-axis or y-axis will change the graph

<h2>Step-by-step explanation:</h2><h3>a. Reflection over the y-axis will not change the graph since sine is an even function.</h3>

This is false because y=sin(x) is an odd function, not an even one. This means that sin(-x)=-sin(x), and a reflection over the y-axis will change the graph.

<h3>b. Sin(x)=sin(-x)</h3>

This is false because we said that sin(-x)=-sin(x)

<h3>c. Reflection over either the x-axis or y-axis will change the graph</h3>

This is true. Since sin(x) is an odd function, then reflection over either the x-axis or y-axis will change the graph as we said in a. So, for f(x):

<u>REFLEXION IN THE X-AXIS:</u>

h(x)=-f(x)

<u>REFLEXION IN THE Y-AXIS:</u>

h(x)=f(-x)

<h3>d. Sin(x)=-sin(x)</h3>

False by the same explanation as b.

What's 5 divided by 3 1/3?
Dafna11 [192]

Answer: 3/2

Step-by-step explanation:

We can start by converting 3 1/3 to an improper fraction. Since 3 is equal to 9/3, 3 1/3 would be equal to 9/3 + 1/3 = 10/3.

Therefore, we are doing \frac{5}{\frac{10}{3}}.

Dividing 5 by 10/3 is the same as multiplying 5 and the reciprocal of 10/3, which is 3/10.

5*3/10 = 15/10 = 3/2.
