Answer: x < 4
Step-by-step explanation: When solving the inequality 3x - 3 < 9, just like an equation our first step is to isolate the <em>x</em> term which is 3x by adding 3 to both sides of the inequality.
On the left, -3 + 3 cancels and we have 3x.
Make sure to bring down the < sign.
On the right, 9 + 3 simplifies to 12.
So we have 3x < 12.
Now, divide both sides of the inequality by 3 to isolate <em>x</em>.
When we do that we get <em>x < 4</em>
So our answer is x < 4.
He has to drive around the track about 1.5 times.
We first find the circumference:
C = 2πr = 2(3.14)(1.6) = 10.048
We now divide 15 by this:
15/10.048 ≈ 1.5
The slope is -2 and the Y-Intercept is at 24
Move the decimal to the right 4 places to get 4 x 10^-4 which reads four times ten to the negative fourth power
