The plan for a gym membership will be a linear equation, in the form y=mx+b, where b is the base fee, m is the cost per month, and y is the total cost. As long as the graph of this line for both gyms intersect, this point of intersection is where the cost for both gyms intersect. If you have two parallel lines, however, there will be no point of intersection.
For example, Gym A charges a $20 base fee plus $20 for each month. Gym B charges a $25 base fee plus $20 for each month. These are parallel and will never intersect.
8.2 grams = 1 mol
Na ________
22.99 grams
First multiply the value of 8.2 to 1. Then divide by the value of 22.99 to determine the number of moles of sodium present in the 8.2 gram sample.
Then use the following equation to solve for sodium atoms.
Number of moles of Na • Avogadro Number = Number of sodium atoms.
0.3566782 • (6.02 X 10^23). = 2.1472 X 10 ^ 23. Or 2.15 X 10 ^ 23.
The answer is the second option - 2.15 X 10 ^ 23.
Answer:
160
Step-by-step explanation:?
Equation of a line is -> m= y2 - y1 all over x2 - x1. Therefore, -1 - 7= -8 and -3 - 1= -4. -8 divide -4= 2 so the gradient is 2.
