Answer:
The answer is below
Step-by-step explanation:
The question is not complete but I would show how this charges can be represented by an equation.
For health club A:
The graph (x, y) passes through the points (2, $136) and (4, $242). Let x represent the total months and y represent the total charges. The equation is given by:
For health club B:
The table (x, y) has the points (4, 173) and (6, 23y). Let x represent the total months and y represent the total costs. The equation is given by:
Let the number of text messages be represented by X.
Then the total cost of David's cell phone adds up to
Since the total cost of David's phone equals $91.40, we get the following equation.
Subtract 50 on both sides
Divide both sides by 0.45
Therefore David has send 92 text messages.
Answer:
T = 2w + 37
Step-by-step explanation:
Let T represent the total amount of videos Rachel has after w weeks
Rachel already owns 37 videos
She purchases 2 more each week
Therefore, after w weeks, the total amount of videos Rachel has can be represented by the expression:
2w + 37
Then the total after w weeks can be modeled by the equation:
T = 2w + 37
For this case we have:
Let:
x: number of points scored by Duncan
y: number of points scored by Eddie
We have:
(1)
(2)
Substituting (2) in (1):
Thus, Duncan could have scored a maximum of 62 points.
Answer:
points scored by Duncan.
