Answer:
x-3 < 9
Step-by-step explanation:
if we know that the liters of milk are 3 or more and less than 9, we have
3=< x <9
where x are the liters of milk.
if we subtract 3 in inequality,
x-3 < 6 with x greater than or equal to 0 because we are talking about a quantity
to solve this inequality, we have to clear x
x < 6+3 = 9 So x < 9 where x belongs to natural numbers
Answer:
You have to substitute the x-value into the equation to see whether the solution gives the y-value.

Answer:
x=1.816298 or x=−1.162524
Step-by-step explanation:
Step 1: Multiply both sides by x^2.
x2=x4−3x3+8x2−16
x2−(x4−3x3+8x2−16)=x4−3x3+8x2−16−(x4−3x3+8x2−16)(Subtract x^4-3x^3+8x^2-16 from both sides)
−x4+3x3−7x2+16=0
(Use quartic formula)
x=−1.162524,1.816298
Check answers. (Plug them in to make sure they work.)
x=1.816298(Works in original equation)
x=−1.162524(Works in original equation)
