Answer:
1,2, and 4
Step-by-step explanation:
I attached a picture with the graph
y= -4 is a straight horizontal line (red line) and
y≤10 will give a horizontal line passing trough y=10 (blue line)
the solution is all points under and on the line y=10
1, 2, and 4 are part of the solution set
(the blue area is the solution of the system of equations)
90 degrees rotation about the origin
Answer:
The value of f(2) would be -40.
Step-by-step explanation:
Given function is,
![f(x) = 2x^3 - 3x^2 - 18x - 8](https://tex.z-dn.net/?f=f%28x%29%20%3D%202x%5E3%20-%203x%5E2%20-%2018x%20-%208)
Substituting x = 2 in the above function,
We get,
![f(2) = 2(2)^3 - 3(2)^2 - 18(2) - 8](https://tex.z-dn.net/?f=f%282%29%20%3D%202%282%29%5E3%20-%203%282%29%5E2%20-%2018%282%29%20-%208)
![=2(8) - 3(4) - 36 - 8](https://tex.z-dn.net/?f=%3D2%288%29%20-%203%284%29%20-%2036%20-%208)
![=16 - 12 - 44](https://tex.z-dn.net/?f=%3D16%20-%2012%20-%2044)
![\implies f(2)= -40](https://tex.z-dn.net/?f=%5Cimplies%20f%282%29%3D%20-40)
Hence, the value of f(2) would be -40.
Answer:
0.03
27
Step-by-step explanation:
Use the formula y=mx+b
m= slope
b= y-int
Rate of change can also be interpreted as the slope.
0.03
The initial value can be interpreted as the y-intercept.
