We are given this inequality,
We will follow these steps to solve it:
Step 1:
First let us bring 10 to the left side.
10 is in addition on right, so we apply opposite operation of addition that is subtracting 10 from left side, we get
Step 2:
Next we have to eliminate -4 which is in multiplication with x on the right side.
So applying opposite operation of multiplication that is dividing both sides by -4.
We have to consider here that when we divide or multiply with a negative the sign of inequality reverses, that is ≥ becomes ≤ and vice versa.
x≥4
Answer is last option x≥4.

Answer:
b(x) = 1,000 * 2.15^x
Step-by-step explanation:
1,000 represents the intial colony size. An increase of 115% correlates to multiplying the said size by 2.15 to the power of the hours elapsed.
Common error: The factor is 2.15 and not 1.15 as an increase of 100% is doubling the amount. i.e. if the increase was 15%, we would multiply by 1.15.

Answer:
(0, ∞)
Step-by-step explanation:
The linear portion is the part that is a straight line. The hole at x=0 indicates that the function is not defined at x=0. Therefore, the domain of the linear portion of the function shown is (0, ∞).
