Check the picture below.
something worth noticing 
so, we're really graphing x+2, with a hole at x = 3, however, when x = 3, we know that f(x) = 5, but but but, when x = 3, x+2 = 5, so we end up with a continuous line all the way, x ∈ ℝ, because the "hole" from the first subfunction, gets closed off by the second subfunction in the piece-wise.
Answer:
The balcony seat costs $9, the orchestra seat costs $9 + $6 = $15.
Step-by-step explanation:
Let x is the cost/price of one balcony seat, in dollars.
Then the cost of one orchestra seat is (x+6) dollars, according to the condtion.
The total cost of tickets is
250x + 400*(x+6) = 8250.
Simplify it step by step.
250x + 400x + 2400 = 8250,
650x = 8250 - 2400 = 5850 ====> x = 5850/650 = 9.
Answer. The balcony seat costs $9, the orchestra seat costs $9 + $6 = $15.
Check. 9*250 + 15*400 = 8250. Correct.
Answer:
8. C=131.88 mm
9. C=40.82 ft
10. A=254.34 in²
Step-by-step explanation:
8. diameter of 42 millimeters- circumference?
Radius is half of 42, so 21 mm
Circumference=2πr
C=2π21
C=131.88 mm
9. diameter of 13 ft- circumference?
radius is half of 13, so 6.5
Circumference=2πr
C=2π6.5
C=40.82 ft
10. radius of 9 in- area?
Area=πr²
A=π9²
A=π81
A=254.34 in²
