Answer:
![3 \frac{4}{5}](https://tex.z-dn.net/?f=3%20%5Cfrac%7B4%7D%7B5%7D%20)
Step-by-step explanation:
1) Add the whole numbers first.
![3 + \frac{1}{5} + \frac{3}{5}](https://tex.z-dn.net/?f=3%20%20%2B%20%5Cfrac%7B1%7D%7B5%7D%20%20%2B%20%20%5Cfrac%7B3%7D%7B5%7D%20)
2) Join the denominators.
![3 + \frac{1 + 3}{5}](https://tex.z-dn.net/?f=3%20%2B%20%20%5Cfrac%7B1%20%2B%203%7D%7B5%7D%20)
3) Simplify.
![3 \frac{4}{5}](https://tex.z-dn.net/?f=3%20%5Cfrac%7B4%7D%7B5%7D%20)
hence, the answer is 3 4/5.
These equations seem tricky, but aren't as hard as you think. Just solve it like you are regularly adding fractions.
Your common denominator is 9x + 9, so
1/(9x+9) = 36/(9x + 9) - (5x + 5)/9
1 - 36 + 5x + 5 / 9x - 9
30x - 30/9x - 9
10x-10/3x - 3
10(x-1)/3(x-1)
10/3
Hope this helped!
Answer:
3
Step-by-step explanation:
To solve this problem you must apply the proccedure shown below:
1. You have the following parent function given in the problem above:
![f(x)=x^{2}](https://tex.z-dn.net/?f=%20f%28x%29%3Dx%5E%7B2%7D%20%20)
2. And you have the function ![g(x)=5(x^{2} )](https://tex.z-dn.net/?f=%20g%28x%29%3D5%28x%5E%7B2%7D%20%29%20)
3. By definition, if you have the function
and
it is a vertical stretch.
4. Therefore, you have that:
![|a|=5\\ 5>1](https://tex.z-dn.net/?f=%20%7Ca%7C%3D5%5C%5C%205%3E1%20)
Therefore the answer is: It is a vertical stretch.
Answer:
<em>A) The reference angle should be </em><u><em>
,</em></u><em> and the sign of the value should be </em><u><em>negative.</em></u>
Step-by-step explanation:
cos(
)
Remove full rotations of 2π until the angle is between 0 and 2
.
cos(
)
Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. Make the expression negative because cosine is negative in the third quadrant.
-cos(
)
The exact value of cos(
) is
