For each tank explain whether or not there is a proportional relationship between the amount of water in gallons, and the time in minutes. If there is a proportional
relationship, identify the unit rate. Use specific features of the graph to support your
answer? Which tank is proportional and how do you know ?

Two times a number plus three times another number equals 4. three times the first number plus four times the other number is 7. find the numbers

If m∠abc = 70°, what is m∠abd? justify your reasoning.  using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°.  using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°.  using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality.  using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.

For g(x) = 5x - 3 and h(x) = [tex]\sqrt{x}[/tex], find (g · h)(4)
