I think the answer for that is 9 (sorry if I’m wrong)
1/64, because if its a negative exponent you use the reciprocal and then 4 to the fourth power is 64
Answer:
3
Step-by-step explanation:
22 - 13 aka cost of bike so it leaves 9 dollars. 9 divided by 3 aka hrly cost is 3
Using linear functions, it is found that option 2 will need the fewest amount of ticket sold.
<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
For each option, we have that:
- The slope is the percentage multiplied by the ticket price.
- The fixed commission is the y-intercept.
For option 1, the earnings with x ticket sales is given by:
y = 9500 + 0.05x.
With y = 13000, we find the amount of tickets that have to be sold to earn $13,000, hence:
13000 = 9500 + x
x = 3,500 tickets
For option 2, the earnings with x ticket sales is given by:
y = 8000 + 2x.
Hence:
13000 = 8000 + 2x
2x = 5000
x = 2,500
x = 2,500 tickets;
For option 3, the earnings with x ticket sales is given by:
y = 4500 + 3x.
13000 = 4500 + 3x
3x = 8500
x = 8500/3
x = 2,833 tickets.
Hence option 2 will need the fewest amount of ticket sold.

#SPJ1
D=number of dimes
q=number of quarters
total is 250 coins so one equation is
d+q=250
dimes are worth 10 cents
quarters are worth 25 cents
I will count cents not dolars
total is 3925 cents
10d+25q=3925
we have
d+q=250
and
10d+25q=3925
multiply first equation by -10 and add to 2nd
-10d-10q=-2500
<u>10d+25q=3925 + </u>
0d+15q=1425
15q=1425
divide both sides by 15
q=95
sub back
d+q=250
d+95=250
d=155
155 dimes
95 quarters
