Let's solve your inequality step-by-step.
−x−4xx>10
−4x2−x>10
Let's find the critical points of the inequality.
−4x2−x=10
−4x2−x−10=10−10(Subtract 10 from both sides)
−4x2−x−10=0
For this equation: a=-4, b=-1, c=-10
−4x2+−1x+−10=0
x=
−b±√b2−4ac
2a
(Use quadratic formula with a=-4, b=-1, c=-10)
x=
−(−1)±√(−1)2−4(−4)(−10)
2(−4)
x=
1±√−159
−8

The answer is 21, hope this helps.
Answer:
2. A 4√3
3. B -5/3
Step-by-step explanation:
Your solving for variable x
do move all the terms containing x to the left and all other terms to the right
so we going to add -0.5y to each side of the equation
0.2x + 0.5y + -0.5y = 4 + -0.5y
them combine like terms 0.5y + -0.5y =0.0
0.2x +0.0 =4 + -0.5y
0.2x = 4 +-0.5y
Divide each side by 0.2
x= 20 +-2.5y
x=20+ -2.5y
Answer:
1 ans: Zero is not positive or negative. Even though zero is not a positive number, it's still considered a whole number. Zero's status as a whole number and the fact that it is not a negative number makes it considered a natural number by some mathematicians.
2 ans: I don’t know
