Answer:
For the First one, 2 + 9 = 11. And 11 - 3 + (-19) = -11
Step-by-step explanation:
Answer:
$30.50
Step-by-step explanation:
b = bagels
c = cream cheese
<u>Given</u>
b = 30
c = 2
<u>Work:</u>
0.85b+2.5c
0.85(30) + 2.5(2)
25.5 + 5
30.5
Answer: Second option
Step-by-step explanation:
You need to make the multiplication of the function
and the function
. Then:
![(cd)(x)=(\frac{5}{x-2})(x+3)](https://tex.z-dn.net/?f=%28cd%29%28x%29%3D%28%5Cfrac%7B5%7D%7Bx-2%7D%29%28x%2B3%29)
You need to apply the Distributive property:
![(cd)(x)=\frac{5(x+3)}{x-2}\\\\(cd)(x)=\frac{5x+15}{x-2}](https://tex.z-dn.net/?f=%28cd%29%28x%29%3D%5Cfrac%7B5%28x%2B3%29%7D%7Bx-2%7D%5C%5C%5C%5C%28cd%29%28x%29%3D%5Cfrac%7B5x%2B15%7D%7Bx-2%7D)
Therefore, the domain will be all the number that make the denominator equal to zero.
Then, make the denominator equal to zero and solve for x:
![x-2=0\\x=2](https://tex.z-dn.net/?f=x-2%3D0%5C%5Cx%3D2)
Therefore, the domain is: All real values of x except ![x=2](https://tex.z-dn.net/?f=x%3D2)
