x = 0, 8
Step-by-step explanation:
Answer:
x > -1
Step-by-step explanation:
Divide the whole inequality by 9.
(+1)>
Subtract 1.
> - 1
> -
Multiply by 3.
x > -1
Answer:
6 ≤x<∞
Step-by-step explanation:
The inside of the square root must be greater than or equal to zero
x-6≥0
x-6+6≥0+6
x≥6
6 ≤x<∞
We can use point slope form to solve for this.
y - 1 = -2(x - 2)
Simplify.
y - 1 = -2x + 4
Add 1 to both sides.
y = -2x + 5
Now, we can input -3 for x and solve for y, or r in this case.
y = -2(-3) + 5
y = 6 + 5
y = 11
r = 11
