Have a look at the first elements of each point: {3, 0, 1, -2, 2}. Since these are all different, no one x value has more than one y-value associated with it, and thus (3,-2)(0,1)(1,0)(-2,-1)(2,-1) is a function.
6. You have to multiply the time it takes to fill up a tank by the number of tanks you have to
Fill up. The answer is 980 minutes
Given: 
Need: 
Solution: In order to solve for the unknown we must subtract 45 from both sides which would isolate x and given us the value.
<u>Subtract 45 from both sides</u>
After simplifying the expression we were able to determine that x is equal to 30.
Answer:
18. 84 ft² or 18.85 ft² when rounded to the nearest tenth
Step-by-step explanation:
2πrh+2πr²
2× 3.14 × 1 × 2= 12.56
2 × 3.14 × 1² = 6.28
12.56 + 6.28 = 18.84
Have a great day :)
