Answer:
-1 * (-3)^2 - 12 = -1 * 9 -12 = -9 - 12 = -21
Step-by-step explanation:
To find out how many Salmon Filet's were served, knowing that 80% of the specials were Salmon Filet, and there were a total of 70 specials in total, we need to find what 80 percent of 70 is. That's because that will lead us to our answer.
Since a percent is something over 100 (per 100), 80% is 80/100 which simplifies to 4/5. That means that we have to multiply 70 by 4/5. 70 * 4/5 is equal to 280/5. Since 280/5 equal 56, there were 56 Salmon Filet's served, or C.
Answer:
(1) For x = –12, g (x) = -9
For x = –9, g (x) = -3
For x = –6, g (x) = 3
For x = –3, g (x) = 9
(2) The principal amount of money is $80.
Step-by-step explanation:
(1)
The expression of g (x) is,
![g(x)=2x+15](https://tex.z-dn.net/?f=g%28x%29%3D2x%2B15)
The complete table is:
x g (x)
-15 ![2(-15)+15=-15](https://tex.z-dn.net/?f=2%28-15%29%2B15%3D-15)
-12 ![2(-12)+15=-9](https://tex.z-dn.net/?f=2%28-12%29%2B15%3D-9)
-9 ![2(-9)+15=-3](https://tex.z-dn.net/?f=2%28-9%29%2B15%3D-3)
-6 ![2(-6)+15=3](https://tex.z-dn.net/?f=2%28-6%29%2B15%3D3)
-3 ![2(-3)+15=9](https://tex.z-dn.net/?f=2%28-3%29%2B15%3D9)
0 ![2(0)+15=15](https://tex.z-dn.net/?f=2%280%29%2B15%3D15)
(2)
The formula for simple interest is:
![I=P\times r\times t](https://tex.z-dn.net/?f=I%3DP%5Ctimes%20r%5Ctimes%20t)
Given:
I = $40
r = 10%
t = 5 years.
Compute the value of <em>P</em> as follows:
![I=P\times r\times t](https://tex.z-dn.net/?f=I%3DP%5Ctimes%20r%5Ctimes%20t)
![P=\frac{I}{r\times t}](https://tex.z-dn.net/?f=P%3D%5Cfrac%7BI%7D%7Br%5Ctimes%20t%7D)
![=\frac{40}{0.10\times 5}\\\\=80](https://tex.z-dn.net/?f=%3D%5Cfrac%7B40%7D%7B0.10%5Ctimes%205%7D%5C%5C%5C%5C%3D80)
Thus, the principal amount of money is $80.
Answer:
yes
doing problems like these you should always worry about the numbers underneath the X instead of the Y.
