The x-intercepts are -6 (put the radical over the 6) and 6 (put the radical over it) or if you need the simplified version they are -2.44 and 2.44
Simplify 2/7b to 2b/7
-1 × (2b/7 + 9) - 8
Simplify 1 × (2b/7 + 9) to (2b/7 + 9)
-(2b/7 + 9) - 8
Simplify brackets
-2b/7 - 9 - 8

<u>-2b/7 - 17</u>
Answer:
Step-by-step explanation:
1 .
- x - 8 < 13
- x < 8 + 13
- x < 21
2.
- x - 8 > -13
- x > 8 - 13
- x > -5
<u>Combined answer</u>
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
