Answer: 6*(13+7) = 60
Step-by-step explanation:
6*13+6*7
6*(13+7) = 6*10 =60
Answer:
5x+2y =-6 ........1
3x-2y = 22 ........2
Add both Equations
we get
8x = 16
Divide both sides by 8
x = 2
Substitute x = 2 into any of the equations
3(2) - 2y = 22
-2y = 22 - 6
- 2y = 18
Divide both sides by -2
y = - 9
x = 2 y = - 9
Hope this helps
Answer:
(2,-17) should be the minimum.
Step-by-step explanation:
The minimum of a quadratic function occurs at
. If a is positive, the minimum value of the function is ![f(-\frac{b}{2a})](https://tex.z-dn.net/?f=f%28-%5Cfrac%7Bb%7D%7B2a%7D%29)
occurs at ![x=-\frac{b}{2a}](https://tex.z-dn.net/?f=x%3D-%5Cfrac%7Bb%7D%7B2a%7D)
Find the value of ![x=-\frac{b}{2a}](https://tex.z-dn.net/?f=x%3D-%5Cfrac%7Bb%7D%7B2a%7D)
x = 2
evaluate f(2).
replace the variable x with 2 in the expression.
![f(2)=5(2)^2-20(2)+3](https://tex.z-dn.net/?f=f%282%29%3D5%282%29%5E2-20%282%29%2B3)
simplify the result.
![f(2)=5(4)-20(2)+3](https://tex.z-dn.net/?f=f%282%29%3D5%284%29-20%282%29%2B3)
![f(2)=20-40+3](https://tex.z-dn.net/?f=f%282%29%3D20-40%2B3)
![f(2)=-17](https://tex.z-dn.net/?f=f%282%29%3D-17)
The final answer is -17
Use the x and y values to find where the minimum occurs.
