Answer:
Q#1.total number of T-shirts for total cost to be equal=10
Q#2.For the total cost to be the same for both companies, the volleyball team would need to purchase 10 T-shirts from each company
Q#3.total of $105 for each company.
Step-by-step explanation:
Q#1
two functions are given
y=10.5x
y=7.5x+30
where y represents cost and x represents number of shirts
we have to find number of shirts to be purchased from each company keeping cost equal
hence we will write
10.5x=7.5x+30
10.5x-7.5x=30
3x=30
x=30/3
x=10
Number of shirts to be equal cost price is 10
Q#2
two functions are given
y=10.5x
y=7.5x+30
where y represents cost and x represents number of shirts
we have to find number of shirts to be purchased from each company keeping cost equal
hence we will write
10.5x=7.5x+30
10.5x-7.5x=30
3x=30
x=30/3
Number of shirts =x=10
Q#3
total cost=y=?
for y=10.5x
put x=10
y=10.5*10
cost=y=105
and for other function
for y=7.5x+30
put x=10
y=7.5(10)+30
y=75+30=105

Answer:
Gene ran faster
Step-by-step explanation:
The fastest time is the smallest time since they ran the same distance
gene ran 90 meters in 16.3 seconds.
alma ran 90 meters in 17.2 seconds
16.3 < 17.2
Gene ran faster
I think isn't anyone of these alternatives because if we put number 15 in the place of y it is x-y=30. X-15=30
X=30+15=45.
X=45
Answer x=-2,-6
The roots (zeros) are the
x
