On a very cold morning, it was -8°f. as the day went on, the temperature rose 2 degrees each hour. which equation shows the temperature over time? a) y = -2x + 8 b) y = -2x – 8 c) y = 2x + 8 d) y = 2x – 8

Step-by-step explanation:

In this problem, the initial condition is -8, because the start of the day, the morning, was -8 °F. This characteristic is really important, initial condition are expressed as y-interception, which is the constant term of a linear function.

So, in this case, the viable answers are B or D, it depends on the ratio of change.

The problem states that as the day went on, the temperature ROSE 2 degrees each hour, that expressed an increasing behaviour of 2. Mathematically, that means the independent variable must be negative.

Therefore, the right answer is D., because it has a positive rate of change, and it has -8 as y-interception or initial condition.

answer is c

step-by-step explanation:

x^(1/6) · x^(1/6) · x^(1/6)   ·x^(1/6) = x^(4/6)   since we add the exponents

4/6 can be simplified to 2/3

the simplified form is x^(2/3)
