2x - 3 > -1
Three less refers to the negative 3, twice a number refers to 2x, and at least negative one is > 1.
I don't get what you mean by "with decimals" but it would be 1

Answer:
f(x) = 3x +5
Step-by-step explanation:
The x-values change by 1 from the first line to the second.
The y-values change by -13-(-16) = 3 from the first line to the second.
Then the "rate of change" is ∆y/∆x = 3/1 = 3. This will be the coefficient of x in the equation. The last choice is appropriate:
f(x) = 3x + 5
Start with x^2 + y^2 = r^2, where r signifies radius. Subst. 0 for x and 9 for y:
0^2 + 9^2 = r^2. Therefore, r = 9.
The std eqn is x^2 + y^2 = 9^2. this is a special case of
(x-h)^2 + (y-k)^2 = r^2 and is appropriate because the origin is at (0,0).
This equation does not have any zeros. Use the formula of (b*b)-4(a)(c).
