First, solve for zero
y2 - 4y > 5
y2 - 4y - 5 > 0
(y - 5)(y + 1) > 0
So where y = 5 and y = -1, the inequality solves for zero. We know that because the term with the highest power of y has a positive coefficient, that this is a parabola which has a limit in the negative, and is infinite in the positive. That means y is less than negative one or greater than 5.
{x | x < -1 OR x > 5, x ∈ ℜ}
This is called an inequality. If x squared is greater than or equal to 49, then x is plus or minus 7 or greater than plus 7 or less than - 7.
Since the question refers to "how much greater" rather than "how much as great as", the answer is that: t squared is (t-1) times greater than t.
You don't. There's no question there, and nothing that needs solving. "16 less than x squared" is written as (x2 - 16)
Yes. (If you subtract -17 minus -18 on a calculator, you get a positive number.)
no - nor less than minus 1.
None of the graphs that I can see!
It can't be solved because the discriminant of this quadratic equation is less than zero
This is called an inequality. If x squared is greater than or equal to 49, then x is plus or minus 7 or greater than plus 7 or less than - 7.
If X squared is less than 16, then the absolute value of X is less than the square root of 16. X will be greater than -4 and less than +4.
Your Problem: X - 4 = ?Current Problem: 3 [squared] - 4 = ?How: When a numbered is squared, it means you multiply it against itself. So, 3 squared equals 3x3.3x3 = 9So, you would then take 9 and minus it by 4, which would than equal 5.Answer:3 [squared] - 4 = 5or9 - 4 = 5
x >2 x2 - x - 6/(x2 - 4) (x + 2)(x - 3)/(x + 2)(x - 2) cross out x + 2 (x - 3)/(x - 2) this is the most simplified this can be
This is the same as 1 minus the probability that neither of them are greater than three. This is 1, minus the probability of getting greater than three, squared. Rolling higher than three has a 1/2 probability, so: P(at least one greater than 3) = 1 - (1/2)2 = 1 - 1/4 = 3/4
1.075 is greater than minus 1.90
Since the question refers to "how much greater" rather than "how much as great as", the answer is that: t squared is (t-1) times greater than t.
Yes, -10 - (-50) = 40 Therefore, -10 is 40 greater than -50.
Since 0.50 squared equals 0.25, 0.50 squared is less than 0.50.
2x2 + 2x - 8 = 2(x2 + x - 4). This can take any value greater than or equal to -8.5
