Answer:
Step-by-step explanation:
In the point (x, y), if x=0, then the point is on the y axis.
If y=0, the point is on the x axis
If both x and y are positive (greater than 0), the point is in quadrant 1
If x is negative (less than 0) and y is positive (greater than 0), the point is in quadrant 2
If both x and y are negative, the point is in quadrant 3
If x is positive and y is negative, the point is in quadrant 4
Taking (-3, 2), since 3 has a - sign before it (and nothing else), it is negative. Since the x value comes first, this means that x is negative. Since it simply states "2" for the y value, it is positive. As x is negative and y is positive, we know that the point is in quadrant 2.
I challenge you to do this on your own - good luck, and feel free to ask with further questions!
Answer:
Step-by-step explanation:
An exponential equation has the form
y=ar^x where y=final value, a=initial value, r=rate, and x=time, in this case
y=28000(0.73^x)
So the initial value is 28000 and r=0.73. Since 0.73 is less than one this is an exponential decay representing a 27% loss per year. So B and F are correct.
Answer:
He purchases a total of 6 tickets: $16 for the first and $5 each for 5 more tickets.
Step-by-step explanation:
Here we need an equation with a constant term and a variable term:
$71 total = $16 + ($11/ticket)*(t tickets)
Subtracting $16 from both sides, we get
$55 + ($11/ticket)*(t tickets)
Dividing both sides by ($11/ticket)
results in
$55
-------------- = 5 tickets (beyond the first one)
$11/ticket
