Answer: Total cost of the models the town buy = $1050
Solution:
The science museum sells dinosaurs models to the town school and town library for $105 each.
The two library buys 4 models and cost of each model $105
Total cost pay by library = 4x105 = $420
The school buys 6 models and cost of each model $105
Total cost pay by school = 6x105 = 630
We need to calculate total cost of the models the town buys
Total cost = Cost buy library + Cost buy school
Total cost = 420+630
Total cost = $1050

Answer: x = 27
Step-by-step explanation:
x/3 - 11 = -2
Add 11 to each side
x/3 = 9
Multiply each side by 3
x = 27
x cannot equal 21.
21/3 - 11
21/3 = 7
7 - 11 = -4
-4 does not equal -2
Therefore, x cannot equal 21.
The x-intercept happens when y=0 which is at x=4 f(x)=0=y so the x-intercept is at (4,0)
the y intercept happens at x=0, reading from the table f(0)=-200 so the y intercept is (0,-200)
so the second option
x-intercept = (4,0)
y-intercept = (0,-200)
is correct
