Hey I have posted a picture the method I use to solve simultaneous equations is change the sign and follow the new sign.
This involves changing the sign for the second equation and solving it
Answer:
1 real solution
Step-by-step explanation:
y=2x^2−8x+8
We can use the discriminant to determine the number of real solutions
b^2 -4ac
a =2 b = -8 c=8
(-8)^2 - 4(2)(8)
64 - 64
0
Since the discriminant is 0 there is 1 real solution
>0 there are 2 real solutions
< 0 two complex solutions
Answer:
C) Volume
Step-by-step explanation:
Volume of any three dimensional figure is defined as its capacity.
Here, if we take the figure of a 3D Prism,
Here,
Perimeter = Sum of all sides
Total Area = sum of Area of all triangles
Volume = Length x Breadth x Height = Product of dimensions
then Multiplying all its dimensions will give us its volume.
Answer:
The answer would be B
Step-by-step explanation:
The reason that we know this is because the line is falling and because it is a solid line then we know that it is ≥ and not just >. the solid line already gets rid of C and D. A is a positive number which would cause the line to go the opposite direction. Therefore B is your only answer left.
