Basically f(x)=5x means whatever number you plug in will be your x coordinate, and the result will be your y coordinate.
(1,5) (2,10) (3,15) (4,20) and so on. 1,2,3 and 4 are x coordinates plugged into the equation, the y coordinate is whatever 1,2,3 and 4 multiplied by 5 is.
Answer:
1 common solution
Step-by-step explanation:
Answer: 8.4 or 8 2/5
Step-by-step explanation:
3 1/2 for 25 minutes and 0.14 miles per minute so 0.14 * 60 since there are 60 minutews in a hour and you get ur answer.
In this item, we first solve for the cost of eating in a cafeteria. From the given it is stated that the cost of eating in a fancy restaurant is 3 times the cost of eating in cafeteria. Mathematically,
3x = 36
where x is the cost of eating in cafeteria.
The value of x from the equation is 12.
In a five-day workweek, she eats at the fancy restaurant once and four times in cafeteria. To determine the total cost,
T = 4(12) + 36
T = 84
Thus, the answer to this item is 84.
Answer:
They purchased 3 tickets for tier seats.
Step-by-step explanation:
From the information given, you can write the following equations:
x+y=12 (1)
45x+60y=585 (2), where
x is the number of tickets for floor seats
y is the number of tickets for tier seats
First, you can solve for x in (1):
x=12-y (3)
Next, you can replace (3) in (2):
45(12-y)+60y=585
540-45y+60y=585
15y=585-540
15y=45
y=45/15
y=3
Now, you can replace the value of y in (3) to find x:
x=12-3
x=9
According to this, the answer is that they purchased 3 tickets for tier seats.
