Hi!
Let's solve both inequalities and check the answer.
y≥x²-4
0≥0²-4
Solve
0≥0-4
0≥-4
This is correct.
y<2x-1
0<2·0-1
Solve
0<0-1
0<-1
This is incorrect.
The answer is D. No. (0,0) satisfies y≥x²-4 but does not satisfy y<2x-1.
Hope this helps! :)

Remember you can do anything to an equestion as long as you do it to both sides
2(x-1)=14
divide both sides by 2
x-1=7
add 1 to both sides
x=8
Answer:
area of one of the basses is 1.44 square feet
area of each lateral rectangular face is 0.96 square feet
SURFACE AREA OF THE PAPERWEIGHT IS 6.72 square feet.
Step-by-step explanation:
3x^3 + 17x^2 + 2x + 21
You simply put x+1 in all the places where x is present on the right of the equation and simplify using PEMDAS.
